(Click here to view the original thread with full colors/images)
Posted by: chad502ex
Hello again peeps!
First and foremost, Thank you Harlen, site owner, for agreeing once again to permit another exclusive DRG450R TT build up thread on ATVRIDERS.com...
Also, xsc_racing28c has agreed to show the peeps an inside look of what it'll take to win on TT race circuits... (hopefully WOT).... not just from an engine perspective, but from what i understand, a complete utter-amazing suspension package too.. Maybe, xsc_racing28c will enlighten us along the building process with photo postings and decriptions of his suspension installation..
The last build up thread was a great sucess and logged over 12,500 hits and still counting... Many ppl participated in questions and comments that were constructive to everyones learning process. Thanks.
All is encourage to participate, and I would hope that this can be another thrill to contribute.
Now, let's start out with a decription of the buildup....

Posted by: chad502ex
Since TT racing is all about top end muscle, I recommended to xsr_racing the following for his 450R:
1. full high velocity porting
2. taper bored FCR carb
3. high compression piston for stock bore
4. superior wet flow intake valves, OE exhaust
5. stiffer valve spring (kit)
6. new head/cylinder
7. programmed ignition curves
8. top end cam selection with retarded cam timing
9. high output exhaust (purchased by xsr_racing28c)
So, along the way we'll go over these one by one...
best of both worlds... wahooo!

so r u doing any crank shaft mods? or is that out of his price range?

that modification is not going to be a measureable power producing mod (in stock stroke configration) and was not discussed.
For the most part, this build will be all top end- literally... 
Posted by: eganracing
wasnt czriders a stock bore and stroke engine to? i thought the these cranks need to be balanced to create true power. I've been talking to local engine builders and they all reccomend balancing the crank and getting a "knife" style rod. they claim it helps the engine reach its potential power faster. im not questioning your work by any means im just trying to learn more about these engines.

czrider263 had a Falicon blueprinted crank with Knife rod. Whenever possible, I do recommend cranksaft work, but it's not necessary to make "true" power. I usually only perform when case is to be spit, or the customer wants to go all out. Crank work can be quite expensive, with the labor in the crankshaft such as balancing, polishing, chamferring, lightning, knife rode installation, the labor to split the case, the time involved in shipping and installation. The adventagous part of blueprinting a crankshaft is that you can have it balanced to the piston pack to reduce harmonics and reduce unnecessary stresses on the bearings.

Chad,
Wow, i'm glad that we got permission to put this build up online here. I'm very excited to start this build and see how it comes along.
As Chad stated, we talked about getting my machine to be as competitive as possible in the EDT National Circuit next season, and this is what we have come up with so far. I chose not to go with a lower end at this point partially due to the major amount of money already going into this project with the motor and suspension, but also because i am only 20 years old and am somewhat on a budget ( meaning I have no parental help in this build).
I wanted to keep my machine as reliable as possible, but also having substantial power to get my quad down the track. I've decided to go ahead with all of the mods above for now and i'm sure i'll end up sending the motor back to Chad after next season, for a freshen and some more intense lower and upper end work, but for now, i'm sure i'll be more than pleased.
As of now, I have pulled the motor and all of the current suspenion out, and am waiting for my new suspension to arrive and be built. The motor will be crated and shipped to chad this week, where he will disassemble it and begin the process above.
I as well as Chad will be updating this thread with both suspension and motor modifications and descriptions as they are completed and I can assure everyone will be liking what they see!!!
Lets get this thing rolling Chad!!!! I will be contacting you soon, and giving you a tracking number on the motor~!!!
Later Guys, JAY

Hey Chad, I may have missed it but, what year motor is this? 04/05 style or 06/07?
Posted by: chad502ex
04/05...
Posted by: TMSmx47
Now see THIS is what I wanna see Chad! Thanks xsr_racing28c for lettin us see the build.
Posted by: czrider263
LETS GO DRG!!!!!!!!!!!!!!!!!!!!!!!
Mine will be hitting the track on the 8th.
will be posting results after.
xsr_racing28c you have made a great choice going wtih chad! he does great work and is a really nice guy. and of corse his motors put out serious power.
like i said my quad is just a monster and is really hard to control.
I suggest a DASA pipe great top end.
Posted by: xsr_racing28c
I am thinking about going with a DASA pipe later on, but for now i'm considering keep the exhaust i currently have.. It gave great top end and has made a sustantial power increase on the seat o the pants dyno...
I currently have an M4 Full System Exhaust.
I'm gonna get everything drained and boxed up later on tonite and throw it in the cooler... I'll talk to you tommorow Chad and let you know the update on the motor.. I'm waiting on the piston, but i just may have them drop ship it to ya. Let me know the scoop on the carb also. Later guys, Jay
Posted by: xsr_racing28c
Chad,
It looks like you should have an 87 lbs package sitting on your doorstep
I'll contact you later on today, just to make sure everything is ok..
Thanks, Jay

Cant wait to see this build. Your builds are probably one of the most informational tools on this whole site...Thanks to Chad, Harlen, and the quad owners for allowing this.
Posted by: xsr_racing28c
I'll let Chad explain more on the what exactly the wet flow valves are, but for reference we are using Ferrea Valves... They are all going to be standard sized valves as well.
I can't wait to get this thread jumping a little more as well.. I'll be having some suspension pics and stuff up very soon.. I just recieved 80 % of the suspension last nite..

haha 80%? Ferrea valves were used on CZriders build too.
Posted by: chad502ex
a valve may assist in flowing high cfms (air only), but its what a valve can flow with fuel mixture is more important.
Flow benches only show part of the story. Flow benches are just a tool, like a monkey wrench is to a bolt...
wet flowing a port or a valve is using 'wet' flow conditions to see the components ability to flow in real world conditions.

Thanks for your positive comments. Comments like this is importtant to me, but equally important to xsr_racing28c and Harlen. Lets hope that this will be a positive learning experience too...
Posted by: xsr_racing28c
I really appreciate everyone putting interest into this build. I'm very happy that we got to post this up for everyone to see and can't wait to get it going further with more information and pictures as we move along on this project.
Chad, start taking some pics as you tear it down.. I can't wait!!!!!!
~Jay
Posted by: mic 902
The last build posted on here helped me learn heaps. This one should be just as good and i think the small differences in how things are done for a different dicipline will be interesting. Keep us posted. 
Posted by: chad502ex
I have received the engine.
I'll be picturing the engine before any teardown. Also porting will be this weekend.
Posted by: xsr_racing28c
sounds good, Can't wait to see some progress. ~Jay

Reasons like this is why I am glad we have these discussions. Something so simple in theory yet I never really thought about it. So far from what I've seen flow benches really aren't even all that useful. According to moto man from mototuneusa a flow bench doesn't even show results on the important cycle of the engine. Any thoughts on this chad?
Posted by: chad502ex
very true. There are other strokes in the Otto cycle that are just as important to consider when porting.
For instance, after in take stroke, where the piston is in downward motion and reaches the bottom of the stroke, the intake charge (with mass) still contains inertia and fills the cylinder even after the piston has already been making its way towards TDC for ignition.... after BDC filling is critical to 'ram' the charge into the cylinder.... the more fill the more 'potential' energy...
there are other positions in the Otto cycle that most porters dont really consider either... but that will be explained when the next generation DRG porting is realeased.... 
Posted by: chad502ex
OK, got the engine.
This is how xsr_racing28c shipped the engine to me to Maryland...
good to go when received...
Posted by: chad502ex
here's the engine, before teardown...
Posted by: chad502ex
I already had a new HONDA 450R on the bench; so, I used it for this build... when the HONDA order arrives I'll replentish my inventory... 
here's typical stock OE porting.. before DRG that is..
Posted by: chad502ex
the stock exhaust side...
many of these most have seen beofre...
Posted by: chad502ex
here's the new compression chamber stock look...
Posted by: chad502ex
i've already started the porting process. Here's the finish of the compression chamber with Stainless steel 36mm superior wet flow Ferrea intake valves and OEM exhaust....
Posted by: chad502ex
I also sunk the intake guides in case in the future xsr_racing28c wanted to put the largest cam profile available...
Posted by: chad502ex
here's the sweat SS 36mm intake Ferrea valves...
picked these up from WPP Racing. Thx Brian.
love em...
Posted by: wppracing
Glad I could help you...
They are the only intake valves I use...
Posted by: chad502ex
compression chamber shaping:
compression chamber shaping is about unshrouding the valves to permit low lift flow and increase the flame front effiiciency. The valves make/break contact with the seat twice so its important that good flow exists not just when the valves are at max lift but also when the valve is near the seat too.
Posted by: xsr_racing28c
Looks awesome Chad!!!! Glad to see your started and on a roll.. I can't wait to see some more progress and hear what you have to say on your ideas
..... Hope to hear from you soon bud, i'm getting the clutch sent out monday for ya to look at.. ~Jay
Brian @ Wpp Racing: I'll be giving you a call monday to talk about possibly getting a new exhaust system from ya..

Are these valves made from a two piece design?
I always though that two pieve valves were not as "strong" or reliable. They are welded together by spinning the two separate pieces in opposite directions and mechanically welding them together. Is that how these are made? Thanks.
Posted by: wppracing
No,
They are a solid one piece design.
Posted by: chad502ex
^^^^^^^ what he said.
Posted by: 400exrider707
Ok thanks.
Posted by: xsr_racing28c
Well I promised I would be showing you all some of the other modifications going into this all out TT build, and here is the latest I have for you. Last week I recieved most of my suspension components. I am currently having the a arms built by JB Racing, so they will be another couple weeks.
In the pic, you'll see: ~PEP Big Bottle ZPS ARC Rear Shock
~JB Racing -1 3/8" Swingarm
~Janssen Billet Carrier
~Lonestar Axle w/ SRP Locknut
~Custom Made Rear Link
Posted by: chad502ex
ok here's the last picture of the compression chamber before porting
then I'll show the exhaust guide chamferring...
Posted by: chad502ex
here' the exhaust guide chamferring..
Posted by: ZRider400
awesome pictures.
any way you would be able to post a pic of the porting tools that you use for certain "hard to reach" areas.
Posted by: chad502ex
OK, before I post the next picture I want to introduce my next generation porting technology dubbed SSAR.
Single Stage Anti Reversion
there will be a DSAR too, but not in this build....
: Stay tuned this month for DSAR
What is SSAR?
SSAR provide a reversion trap and works in cooperation with DRG porting. When the piston completes the exhaust stroke and the gasses are being pushed out the exhaust port/pipe, the piston begins to draw on the intake stroke pulling some of the gasses it just pushed out back into the cylinder contaiminating the fresh charge. Anti-reversion prohibits and decreases the reversion amplitude for every step it tries to climb back into the cylinder.
Anti-reversion porting is about one-way porting, not flow that works both directions as most port jobs pictures show. Nect time you see a picture of porting, imagine if the port works one direction equally as the other....
Posted by: chad502ex
here's what i mean...
drag a finger from the valve to the exhaust port header flanger and it'll roll easily over the ridges.....
but,....
push you finger inward into the port and you'll catch each ridge....

here's xsr_racing28c leak down test before teardown...
looks like he was ok with valve seal and ring seal...
Posted by: chad502ex
interesting enough was the condition of the plug when I pulled it to perform a leak down test...
looks like aluminum on the plug...
Posted by: chad502ex
this will be for a DRG 43mm taper bore FCR carb.
Posted by: chad502ex
of coarse since XSR_RACING28c will be getting a build, I mentioned that I would upload DRG curves for him.....
Posted by: xsr_racing28c
Man you just made my day!!!! Those porting pics look great!!! I can't wait to see more....
Here are my front shocks i'll be using.
~PEP Big Bottle ZPS ARC Front TT shocks
(Pep Shock Covers)
Posted by: chad502ex
xsr_racing28c
please explain why you selected those shocks and components....
What is required for TT suspension?
Posted by: chad502ex
Baldwin piston to be used...
Posted by: xsr_racing28c
Alright, well basically I decided to go with PEP shocks all around is because of all shocks i have used, I think that PEP shocks are probably the best quality. They are a little leighter weight than my previous Axis and Elka setups, and the adjustability on them are amazing.
I use the ARC (adjustable rebound and compression) shocks because it gives you a very wide range of adjustability for various track conditions.
TT racing is not only about having a big powered motor, but also how to keep that power planted, and with these shocks I am expecting to put the most power to the ground as I can.
All three shocks use ZPS ( Zero Preload System) which allows the shocks to have alot of sag and also they give a sort of slack when under acceleration, so that your front end isn't up in the air, when you should be controlling your steering.
Each shocks is specifically valved for TT racing and they each use larger reserviors to dispurse the heat easier.

Yea the plug does look to have a little bit on it.
The jetting didn't seem to be too lean, but who knows. I havn't run the quad for about a month before i sent you the motor, so i can't even tell you if i noticed anything, but i check everything before i go out... I think i used a 190 main.. but i dont' know for sure.
Posted by: czrider263
Looks sweet chad!!!
Posted by: xsr_racing28c
For this build, I will be switching over from my current long travel setup, to a standard travel TT suspension package.
I've decided to go with JB Racing products not only because they are quality build components, but also they have great customer service, which means alot to a racer.
Up front I am going with JB Racing +2 TT a arms built from chromoly steel, which make them strong and also lighter weight which is importants for this type of racing. The arms feature two tabs on each lower arm to accomidate for the lower shock mount, and also it gives me a place to easily mount my Rath adjustable Swaybar.
Back in the rear, I am using a JB Racing Tubular Chromoly Swingarm that is 1 3/8" shorter than the stock swinger to along more weight to be transfered over the rear wheels, thus allowing more power to be put down to the ground.

I'll take you up on that offer, the money tree that I planted in the spring is finally blooming some bills, I should have TT setup in the next.....oh......20 years.
LOL! I would love to make it to a TT Race with you next year! We will have to check our schedules and see what we can work out!
Posted by: xsr_racing28c
Sounds good bud, Well forsure we'll get a ride in sometime next year. I am keeping the YFZ for now, so i'll still have a quad to ride off the track.....
Posted by: patrickj75
jay,
where did you get your shocks from? how long did they take? price? thanks!
patrick
Posted by: xsr_racing28c
I bought them off of a pro rider (Zac Willet) and they were setup by SF Racing. I'm not sure what the shocks cost new, but i'm guessing around $1300-1400.
Chad,
Anything new?? I'm anxious to hear from you on some of your ideas, just wondering what your thinking on what we talked about the other nite. Thanks, JAY

working on the intake now. it takes the longest to work.
hopefully tommorow night it'll get done and setup for pouring. your valve spring kit will be here on thursday, so, i want to have the head complete by them for spring installation. Once the head is done, i'll tear into your engine and measure what we have with your new cylinder, your new piston, your cam, and the clearances available to consider our talk the other night...
I'll fill everyone else in as we continue..
Posted by: xsr_racing28c
Alright sounds like everything is moving in a positive direction!!! Can't wait to hear from you on the other things we've talked about, it kinda makes me giggly talking about how badass this motor is going to be!!!
BTW: I sent out the clutch kit today for you to check out, you should be getting it within the next couple days.. TTYL man, JAY
Posted by: xsr_racing28c
Chad,
Just a heads up, I have a DASA on the way!!!! I figured that you would like to hear that!! I'm not sure if i'm getting the specific TT header pipe with it, but i'm waiting to hear back from them on it.
~Jay
Oh yea, and i have Hardcore Engineering Front and Rear Hubs on the way also for the 450r just to touch up the rough edges on this build.

DAY 5:
very cool with the DASA exhaust and the other goodies....
i'd need to get the parts for machining out by friday (goal)...
Posted by: xsr_racing28c
Sweet Deal Chad!! I'm so glad to see this all going smooth for us. If you don't mind, i saved that picture of the head to my computer.. that thing looks so bad ***!!! Can't wait for the intake side pics to be posted 
Posted by: kfx008
can u post a pic pf the dasa tt pipe please
Posted by: xsr_racing28c
I will be sure to post a pic of the DASA TT pipe once i recieve it. They told me that it was gonna be shipped out monday of this upcoming week, because the need to build a special header pipe that is specific for TT.
Chad also called me tonite and informed me that all of the parts were in his hands and ready to be machined and installed. The only thing he is waiting on yet is the FCR Carb to show up at his door, but we are thinking it should be there tommorow.
This build is going along very smoothly and I'm thrilled at the amount of time Chad has spent on the phone and through emails carefully planning each phase of this build. DRG is truly a great company to work with and I can't wait to be able to have the finished product in my hands!!!
Thanks a ton Chad!!! ~Jay
Posted by: patrickj75
i watching this build closely. i'm hoping to have Chad do some motor work for me before next season starts.

Day 6:
WOW, thanks JAy. I appreciate your good words. Your correct, everything is going extremely well thus far and I have just about all the parts, except for the carb to aggressively begin. We'll see the inners of your engine when i disassemble her tonight. Lets hope i dont find any surprises when i take her apart. I'll be dry fitting and measuring clearances for machining...
I love your avatar picture of the SSAR and sig.... thx.

Don't say that Chad..
I'm sure everything is good, because this motor really doesn't have many hours on it, and it hasn't been pounded like alot of other machines out there.
About the Avatar, man it looks tight.. thats my favorite pic yet!!!

the concept will work equally well on all heads had the porting not been fudged up.
exhaust port shape with SSAR is critical though...
spacings between steps were determined for tuning, as with port shape,...
I usually do not prefer to try to port after someone else has ported because sometimes the material may have been removed were i can't get it back...

Dave,
Are you unhappy with the porting you have??
You could always just buy a new head and start from scratch as i have. If anyone is wondering, we decided to go with all new upper end components just to be sure that we are starting fresh. This means we have a brand new head, Valves, Spring Kit, Cylinder and Piston. I just figured if i'm going to go ahead with this build i might as well go the extra step and just buy all new components. Plus, i'm sure Chad is much happier working on new, clean parts...haha..

Hey Jay,
I honestly can't tell you about the porting, I have yet to ride it, 8 days and counting......LOL! I have ridden it once at the track and it was before the rear shock was set up properly so I was more worried about that. The previous owner said that it was kicking out 53ish HPs so that is good for me, but the SSAR intrigues me~!
Dave

I just wanted to say that this thread is awesome and very informing and when its time to get my motor done Chad will definately be getting it.

I see... Well I promise that i'll let you jump on mine once its done, and just see what the power feels like. I have never been on a quad with this amount of motor work done to it, so i'm sure i'll be amazed at how much extra i'm gonna have under me. I'd also like to feel the 06 power, so maybe you'll let me jump on yours??
We are hoping for 35 hp outta mine
so stay tuned for a dyno report... haha..
MR BIG: Thanks for the compliment!!! I can assure you that you'll be happy working with Chad!! Keep an eye on this build and see what the finished product will be!!!! There may be some suprises later on, we're not sure on what the finished product will be yet...

Sounds like a plan! I just need to get some flat track tires wheels and a sway bar and I should be good to go to a race with you! You know I will let you ride my turd!

Well, we should pick a date and a race to go to! Are there any in the IOWA, ILLINOIS, MISSOURI, or KANSAS area that you plan on making a trip to?
Posted by: xsr_racing28c
I'll check the National Schedule for next year and we'll pic one out.. I'll keep you posted on that..

????
Whoa.....I guess I better find a TT Track to practice on! LOL! 
Posted by: xsr_racing28c
haha..
I'll try to find a smaller one in Illinois somewhere where we can meet in the middle and race. That way you don't have to jump in a National right away.. ~Jay

inpection during teardown..
Posted by: chad502ex
on the head side.
not a bad looking burn IMO.
Posted by: chad502ex
You see what i see?
here's signs that the ol' JE piston had piston skirt rub. not bad just exists...
Posted by: chad502ex
here's what i mean...
Posted by: chad502ex
no signs of underneath discolorings from excessive heat.
plenty of lubrication, even though the JE wrist pin seems binded on removal...
Posted by: chad502ex
not excessive but generally looser than most builds i've done, but still in tolerances by another .014"...
Since I got thing available, I always take a few extra minutes to check what i can for the customers.
Posted by: xsr_racing28c
Chad,
I just got your message on my phone and everything sounds pretty good. I will be able to call you back but not until about 10 my time, so if its ok if i call you i will, but let me know. I just want to discuss a couple of things, but i don't want to bother you late. Just let me know bud.. Thanks , Jay
Posted by: chad502ex
OK the good stuff now.
Here is the piston to valve (P-V) clearances with a 04 crf camshaft, Baldwin 14:1 piston...
As you all can see plenty of room.
What's rather impressive is the measured squish on the Baldwin. With the stock 0.027" thick OEM gasket and the "in-the-hole" or "below deck" measurement of 0.020", the total squish will be the sum of the two at 0.042"...... not bad at all.... I was hoping to sqeeze for less squish and machine the cylinder, but honestly 0.035" is about perfect... I don't like getting more that 0.015" below deck- so we'll go with that cylinder height.
we could deck the head and get more compression? what ya say xsr_racing28c?
either way- I think twisting the camshaft back to adjust the P-V clearances will be required... Whats great is I already sunk the intake valve guides to allow for larger profiles down the road if desired... but if we decide to deck the head, i'll be decked in for the crf so i need to know now if you ever have the desire to get more top end cam with more overlap... it's up to you.
0.372" in lift
0.312" ex lift
a Web 208 is the following:
0.408 in lift
0.342 ex lift
the bigger the valve lift on another cam selected will decrease the P-V clearance pictured. A 208 would decrease intake P-V to about 0.055". you dont want to less than that!!!!!
...but were not doing the 208 on this build, we are doing the 04 crf cam

Posted by: xsr_racing28c
Sounds good, I'll talk to you then.. All the pics look good and it looks like your coming along really well.. Can't wait to figure out our next step... Talk to you tommorow..~Jay
Posted by: chad502ex
Well, I've been pushing the math a bit for the xsr-racing28c build..
conservatively speaking-
A. looks like we can sit at 14:1 and probally dyno at about 52-54hp.
B. we can deck the head 0.020" and get near 54-56hp at 15.25:1
C. we can deck 0.030" and get near 56-57hp at 16:1
D. sqeeze everything out with decking 0.040" and get 57-60hp at 17:1...
Hopefully this demonstrates to all the peeps how the Pro's are getting 60hp....
BTW: this is static compression ratio, not dynamic compression ratio with cam overlap specifications included...
xsr_racing28c, you did say you want a reliable build, right? now, the choice is yours.. the more of an edge you want the more you must roll the dice with reduced P-V clearances...
Posted by: MR.BIG
So many choices I would chose option A!
With the 14:1 piston what is the minimum octane you can run?
Posted by: chad502ex
DAY 7:
well, if he goes with option "A" i could probally complete the build this weekend if I work Saturday and Sunday on it (minus the carb getting machined).
Posted by: xsr_racing28c
Chad,
I'm gonna want to talk to you on the phone about the options, so i plan on calling you a little after 5 your time tonite. We've talked about it all before and i'm leaning towards doing a little bit of machining, but want to talk to you..
Thanks man, Jay
Posted by: czrider263
Chad this winter after the season i might be up for squeezing my motor a little tighter IDK...
Let me know about this weekend on you being there to help dyno tune.
3 1\2 hours on web 208 still good and crossing my fingers LOL.

kewl. I want to get with you too real soon to dyno, just not this weekend.
Glad to see your build is going well and you were able to do well your last race. We'll have to discuss some options. I'll talk to you about it soon.

Great. I'll start the case splitting this weekend after I complete the head.
Be sure to get the crank balanced to the entire Baldwin piston pack weight. You'll have to tell the weight to Falicon so they can harmonically balance your piston to the crank...
wahooo!! 
Posted by: xsr_racing28c
Will do Chad, Janssen told me that they are contacting Baldwin tommorow for the weight to notify Falicon. I'll make sure everything goes smoothly so we get it back and installed asap..
Man this build just keeps getting better and better!!! ~Jay
Posted by: xsr_racing28c
Alright i have a couple of questions:
What kind of fuel do you think i'm going to be needing to run with the setup that we discussed tonite?
Also,
When you said you found deposits on the spark plug that looked to be aluminum, did you find out where that came from??

nope, the piston had some shinny scrath marks. maybe this is where it hit the piston and removed some shavings that collected on the plug... it could have been something entered the cylinder, but it doesn't matter- it looked fine.
Posted by: xsr_racing28c
Alrighty cool..
Well let me know how the rest of the weekend goes with teardown and all.
For all that don't know: Today I've decided to go ahead and throw down for a whole new lower end. We are going with a complete Falicon Supercrank Assembly which has been balanced, blueprinted, welded and trued to reduce all harmonics that will cause the crank to be out of balance.
Chad and I discussed doing the crank and we just thought that by putting down this much power, a lower end to withstand the extra demands of power was a good idea though essentially it won't give any power gains, but will just make the motor more reliable.
We also are just going to keep the motor at 14:1 compression for now to see how it dyno's out, and at a later time the head will be sent to DRG again, to get some more elaborate machining done to the head to put out some more usable power!!
Thanks to all who are interested in this build, Its a first for me, so i'm very excited to be working with DRG to make this motor a monster and keep us competitive on the track.

Chad,
If you could do a full list of mods and new parts and work going into the motor portion of the build including the lower end that would be awesome.. I would rather you do it, since you know exactly what is going into this puppy..
Once all of the new parts come in here for the rest of the quad, i'll get a list going for suspension and misc items..
thanks, Jay

carb teardown for 43mm taper bore....
the throttle body is ready for machining.
the NOSS adapter is welded on prior to taper boring so that the NOSS adapter has smooth transition into the bore of the carb.
Posted by: chad502ex
xsr_racing28c,
I'll be sending you another parts list for the bottom end parts like gaskets, seals, new bearings. We'll need to order the HONDA parts on Monday.
Posted by: xsr_racing28c
Sounds good, just invoice me through email like you have done in the past. I will get you money over right away.. ~jay
Posted by: chad502ex
OK, I' will have the bottom end order invoice sent to you by tommorrow night.
Also, your carb is at the machinist.
Posted by: xsr_racing28c
Alright sounds good Chad!! i can't wait to see it done when it comes back.
Have you started on the bottom end teardown yet??
Posted by: chad502ex
no. probally wont spread parts arounf for a bit.. 
Posted by: chad502ex
ok, now that the build has been delays due to xsr_racing28c's desire for a blueprinted crank while I have it in my possession, I've gotten the list of small HONDA parts that we'll need to complete the crankshaft installation....
xsr_racing28c- I'll send you the invoice tonight for the new HONDA parts order plus labor.
Also, I'll be finishing the head this week, assembling your carb, programming your ignition, splitting the cases in prep for the arrival of the Falicon crankshaft..
Let me know if you have any further questions...
Posted by: xsr_racing28c
Sounds good Chad, Once i get the invoice, i'll have a money order out to you right away.
The only thing is that the stock crank is gonna have to be sent back to Falicon for the core..
Otherwise, all sounds good!!!

caint wait to see the dasa tt pipe

Talked to Janssen Motorsports this morning and the Dasa exhaust should be here late this week or early next.
I'll post pics when it arrives
Posted by: kfx008
sweet thanks
Posted by: Chino886
Hey Jay/Chad,
I might have missed it in the thread somewhere, but what is the difference in the DASA TT pipe as opposed to the DASA "shelf" pipe?
Thanks,
Chinerweiners!
Posted by: xsr_racing28c
Dave,
Here is a really really bad drawing of what the TT pipe looks like incomparison to the regualar mx style header.
The TT pipe is essentially shorter than the normal style, because it bends alot quicker and heads back to the silencer as the regular style makes a more horseshoe style bend off the head to build more low end power. This isn't that good of a analysis of the differences but for now this is all i can give ya. Once i get the actual pipe here, i'll show the differences.
Posted by: slosh13
That is such a good drawing

Posted by: xsr_racing28c
Thanks man!!!!
I think it at least gives a little idea of what the difference is.
~Jay
Posted by: slosh13
this is a great thread going with you and chad. Be sure to keep up on the progess!! Seems like he's taking care of you very well
Posted by: chad502ex
OK wahoooo! back on track... just finished pouring the intake DRG..... Hopefully, tommorrow I'll finish the head to post pictures for everyone... I really like what i've done thus far on this SSAR.
Friday night, I get to pick up the carb from the machinist. He's been real busy building his jet-shi's too... The carb is real sweet all brand new looking out-of-the-box and all.... I'll bore in the intake boot against the head and the carb for absolute smooth flow transitioning...
TT headers are smaller in length to build more top end power. The longer the intake tract, or the exhaust, or both the more low end it develops....as, the shorter the more top it'll develop.. and since this build is all about top end, that's what will suit the build the best. xsr_racing28c was right... except that drawing will go down in history Jay LOL!!!
Posted by: xsr_racing28c
Yea Chad is definatley a great person to have build your motor!!! I'm really looking forward to seeing him build the motor up once to crank arrives at his door. It should be a week or so, and then the assembly process will insue...
Thanks Slosh13 for the comments also!! ~Jay
Posted by: chad502ex
Thanks I appreciate you good comments.
Here is the infamous SSAR signature. Kinda like sstamping a serial number on the side...
DRG on the other don't worry..

Posted by: xsr_racing28c
Looks super sick Chad!!! You just need to figure out how to change that first S to a D once I sent back my head next year for the DSAR..
It'll be a stealth DSAR in SSAR skin...
Anyways, Great Job and glad to hear the head is pretty much summed up!!! Oh yea and thanks for the help before on the phone Chad.
~Jay
Posted by: chad502ex
hey xsr_racing28c,.... on another TT note, I just purchased a set of 20 x 10 x 10 soft American Racer rears on Douglas Black label, ...
you have any thoughts as to what most TT racers use?
Has most TT racers thought about tire diameter and tire roll-out advantages?
just wondering your thoughts on these topics...
Posted by: MR.BIG
Thats the size I use to use. I use to use hoosiers, Mccreary, and american racers came out towards the end before I sold my bike.
Posted by: xsr_racing28c
Chad,
What compound are they?? sd23, sd33, sd38? also, yea TT'ers also check rollout to make sure that they are using the same tire size on each side. What did you get them for?? Dyno?? I use 10x10 American Racers as well...

Yea if you could ship it back with the motor that'd be great, only because i can use them for spares if i even need them.... ~Jay
If you send me the old head, i'm only going to get more depressed

the return of all your spare parts could add to your return ship weight significantly... I'll send the spare engine.. hehe.
Posted by: xsr_racing28c
It's up to you how you wanna do it. You can send the stuff back now if you want, i'll just paypal you the money for shipping.
About the clutch stuff... Do you think that the clutch i sent you is gonna be an improvement?? You said something about barnett springs, are the DP ones i sent good enough?
Also, the falicon should be to you as soon as next week.. Probably the following week early though.

ok we'll work it out...
the HONDA bottom end parts will get ordered tommorrow so next friday hopefully i'll have them to assembly your build next weekend..
barrnett springs are stiffer. your springs were about 5% stiffer than stock.. we have more than 5% more power putting through the setup/// 
Posted by: xsr_racing28c
sounds good chad! I will keep up on the crank and keep you posted.
I heard from jb racing today and my tt arms are done,so I should have the chassis back on the shop floor by next weekend hopefully.
overall,the build is going nicely! I'm getting very anxious though!
-Jay
Posted by: xsr_racing28c
Just wondering if there has been any further progress on the motor or carb Chad??
Posted by: chad502ex
i pick your carb up tonight from the machinist.
waiting on the new crank and bottom end parts to arrive...

Jay I can't wait to see it all put back together, and Chad you never cease to impress me sir! 
Posted by: xsr_racing28c
You can't wait to see it put back together??? How do you think I feel??
I'm so excited to see this quad up on all fours and with a motor installed. Its been bare frame for the last month and a half..
The bottom should be there hopefully later on this week or early next.

At the moment, looking at redoing the whole bottom end. Because of the crank finally seizing. So new piston, cylinder, crank, possibly some modifications to my current FCR.
Posted by: xsr_racing28c
Eeeekkk sounds like a horrible scene!!! Well I'm glad i decided to just go all out and replace my whole bottom end as well instead of sticking with the stocker, cuz i would hate to do all of this upper end work and then lose it all due to a lower end blowout.

Yea thats one reason why I may even put a new transmission in it while its taken apart. I'd rather just rebuild my current motor, and know for a fact everything is new, than buy used, and be screwed.
Horrific is an understatement, pulling a oil filter out covered if shavings, about brought a grown man to tears.
Posted by: chad502ex
OK xsr_racing28c, I've got a 'core' all boxxed up for your crank. I'll ship one of my old cranks in my spare parts bin so you can get your 'core' money back as soon as possible.
Posted by: chad502ex
and you knew I had to assemble your sweet new carb tonight... i just could let it sit there ready to be assembled so i did it...
wahhhooooo!
this picture is just after i picked it up from getting machined...

here's the new DRG 43mm taper bore carb with integrated NOSS adapter machined into the throttle body for smooth transitioning...
wahhhhooooo!!!

Ahhhhh it looks SICK!!!! That carb looks wicked Chad!!
I'm glad to see now all we're waiting on is the crank..
JAY

any new news on the build??
Posted by: xsr_racing28c
Well after all, we are still waiting on the crank to arrive at DRG, but i did get word Thursday that the Falicon was to be shipped out Friday at before noon, and should arrive at DRG mid next week.
Other than that, the motor is at a stand still for now being that the crank is in transit. As for the chassis and suspension, the a arms havn't showed up yet, but i have gotten some progress on the other components of the quad.
I did get to install my new DG ProPeg nerfs w/out heelguards, and also a couple other things have shown up like a CRF perch and lever(clutch), a 3.2.1 Carbon Fiber Gas Cap, and also today i just picked up my Front Hardkor Tapered Hubs....
Originally i was going to go with front and rear Hardkor hubs, but due to some flaws in the rear hubs, Hardkor is suspending build on the rears until they have fixed there current problem with a few hubs that have come back with cracks.
Here are the fronts.....
Posted by: chad502ex
Since this build has SSAR, and I'm waiting for his crank to arrive next week, I thought I'd finish my DSAR this weekend...
here's a sneak peak of DSAR as 'DRY FIT'- before pouring:
Posted by: chad502ex
hey XSR_RACING28c:
tommorrow I'll finish the logo on your carb, and flow the intake into your head and carb..
I'll take pictures too..

Posted by: 400exrider0004
woah!!!!
Posted by: GPracer2500
Woah is right!
What are we looking at there?
BTW Chad, did you ever get that sample magazine issue?
Posted by: chad502ex
no copy of the periodical of the DLC coating, but i've found out that it is super hard coating, DLC, that we used on czrider263 custom "FLAT" Ti intake valves.... You'll see real soon that "FLAT" is out with my next product release.... 
DSAR is Dual Stage Anti Reversion that uses SSAR technology along with intake anti reversion technology to help 'store' the pressure at the intake valve backings to 'ram-air' the intake charge into the cylinder upon valve opening. Because of the intake valve is closed during ~450 degrees of crankshaft rotation, a pressure builds at the back of the intake valve due to the ramming effect known as rarefaction intake waves.... These rarefaction waves are elastic in nature and have a damped oscillatory nature with energy. DSAR 'stores' this energy within the 'traps' of the intake porting and inhibit backward pressure flow out the intact tract... As opposed to the stepped design on the SSAR, the DSAR intake port has integrated 'traps' that permit forward flow but 'traps' outward flow to the air filter. Without DSAR intake 'traps', the reverse pressure at the back of the intake valve can easily flow back to the carb where it stalls fuel flow out the carb metered fuel circuits. DSAR intake anti-reversion uses the energy of the refracted waves to constructively interfere with FORWARD waves theoretically provides an entire RPM gain throughout the power curve.

Very interesting. What do you mean by "dry-fit" before pouring? What are you pouring?
I'd be curious to see the reaction from the crew over on the org. Although, I'd understand if you're not too keen on sharring over there--with the drama, tension, agendas, and the rest....I bet it'd be entertaining though!
