My Banshee Overhaul!!
(Click here to view the original thread with full colors/images)

Posted by: Hondamaster5505

Ok guys, this is officially gonna be my build-up thread. Keep in mind, we arent made of money, so this build might take all summer and might not.

What im starting out with:

1988 Yamaha Banshee
UFO Plastics
New Holeshot tires
Electrical is shot
Motor is tired 75/95

Rear rims are slightly bent, and the whole bike is missing bolts.
Heres some before pics:

Plans:

1) Yellow full Fenders

2) Gloss Black Frame

3) Yellow J-arms

4) Yellow Swingarm

5) Wiesco Pro-lite .030

5) Toomey T5 exhaust - Just Got

6) Milled Head

7) YFZ Shocks

8) Boost bottle

9) Stainless Steel Bolt Kit

10) Douglas .190 front rims

This is going to be a fun build. We are first going to straighten out the electrical so we get spark. After I know we are going to get spark, we are tearing the entire thing down to every last bolt. From there, we are doing the power-coating and engine rebuild. We will slowly re-assemble after that. I can't wait for the end product.

This will be my main ride as far as riding in the coalmine areas and other wide-open areas. It will also serve as my TT bike on the weekends. This is exciting.

On a side-note:

The plastics are going to be cleaned up and for sale or trade. We want yellow uncut plastics, but might take other colors as well.

If you want to trade, we can try to work something out. They are aftermarket.

It's always fun to have a quad to build up, and pics are even better

Oh, and in my opinion..if you already have a boost bottle kicking around then I guess you could install it. But if you don't and you plan on buying one...that will just be a waste of money...

Posted by: Hondamaster5505

Update:

We found a nice guy over at bansheeHQ who had a load of banshee parts.

For $150, we bought the following:

(2) Wiring harness's.

(1) Coil

(3) CDI Boxes

(1) High-Output Stator

Plus, there was some more I think. He gave us a good deal. The stator alone is worth that much. now when we recieve it, we will put all new electrical components in and hopeflly get spark. All the stuff we bought off him works, it was off his own personal bike that blew up. After we get spark, we'll begin the tear-down process.

Dinner:
I am buying a boost bottle. My dad bought his banshee the way it is, and it pulls so awesome and has so much power, im duplicating his engine. His just happens to have a boost bottle.

As long as you don't hope all that power comes from just a boost bottle....

No no no, of course I don't. Like I said, his runs so damn good, and was dyno'd at 52hp without porting, so I want to make a clone of his engine.
He happened to get one that was done by a professional at yamaha who actually knew a LOT about banshee's. The guy before him dropped it off with $1800 and said make er fly.
Well, after they bolted on FMF Fatty's with PowercoreII's, Milled head, and a boost bottle, then jetted it spot on, they dyno tested it. 52hp. Thats pretty good for a damn near stock engine.

So yeah, thats the reason for the boost bottle, lol.
I can't wait till the electrical's here so I can start disassembling this beast!

Dinner, wheres your build-up thread? lol.

I noticed in your sig you put undergoing build-up.

Thanks for the help offer.

Once we get the electrical straightened out, it'll be a breeze. The motor isnt a problem at all for us. Once we get the new electrical stuff, the rest should be a breeze.

If we do encounter any problems with electrical or something, ill be back

IMO i wouldn't run the J arms. they're a bit scetchy.

IMO, I kinda like the J-arms.

They ARENT gonna break with my kind of riding. Maybe if you race MX and beat the hell out of them they might.

Actually, they probably handle better than A-arms, because its less mass that has to travel up and down.

I mean, yamaha raced the baja on the damn thing and they didnt break.

The only downfall, BUSHINGS. It'll eat em like a mother f'er.

That you will,lol. One of the reasons I'm switching over to an a-arm frame. And because I'll probably run YFZ A-arms and shocks..

Posted by: Hondamaster5505

UPDATE:

Just recieved all of the electrical last night. When I get a chance, im gonna start installing all of it and see if I get spark.

Posted by: Dinner

Should go pretty easy for you, hell I have my electrical harness on my shop floor, cutting certain wires I don't need anymore and making it look a lot better.

Good luck, and get some pics

Sure will!

I may or may not put it on tomorow. I know it'll be easy, but I dont want to leave it half done.

We're drivin our quads down the street tomorow, because our neighbor has a huge field, but some trails next to it in the woods. Then further down the street theres a sandpit.

After we get back, I might start.

Which actually a boost bottle doesn't give the motor jack for power to start with.. they just vibrate around and cause the intakes to crack and cause air leaks.. I'd just leave the stock cross over tube and run 10mm reed spacers instead.

The one on my dads hasn't vibrated or cracked AT ALL. Plus, if you look them up, it does make sense. It stores some air so when the motor goes to suck more in there's some right there to compensate for the air missing in that split second.

So anyways, im making a clone of his engine. He has a boost bottle. Even if it doesn't so anything, ill find a cheap used one anyway.

And reed spacers don't do anything either, guys just run them to clear clutch arms when they are running larger carbs...

Posted by: Hondamaster5505

Installed the harness and....

NOTHING!

We're almost positive its the stator now. We are getting an aftermarket one soon, so that should be that. We needed a new harness anyway, this one is real nice and has all the plugs.

Posted by: 400exrider989

dude trust use banshee guys when we say boost bottles are a waste, search them up on BHQ they crack, cause air leaks, and make the motor run some what lean for that split second you are talking about, that is why they eat up rings and cause confused jetting problems, leave the stock cross over tube on and you will be fast then your dads because it weighs 1 pound lighter, those that think boost bottles and reed spacers are power upgraders need to research it, you'll be happy you didnt spend the 30 dollars on the boost bottle and buy some gas and oil for it instead, BTW just wondering whats your name on BHQ? and who did you buy the parts from?, stick with the j-arms its cheaper then switching and they are lighter and still strong, also add to your list a T.O.R.S eliminator, they are banshee owners best friends, if you save the money from the poop bottle you could almost but the T.O.R.S eliminator kit, and get rid of the parking brake it also causes some problems with electrical, actually that brings me to maybe figure out your no spark problem it may be the T.O.R.S acting up on you, also if you are on a budget dont buy the VF3 reeds they work good but are expensive, buy the boysen carbone reed petals, they work just as good for lower power motors, also i recommend cometic gaskets, i like your color choices too, Dinner how far are you on your build now? i seen it was down to the frame, what colors you going with?

i love builds, take lots of pics, good luck

I know, i know, boost bottles are a waste. I don't care. We havent had any of those symptoms with my dads at all. I know they dont add anything.

I was always planning on keeping J-arms, no matter what people say. Less traveling weight= better suspension actions. Plus they are just as strong.

The TORS are unplugged and they are disconnected right. We know lots about banshee's and that some go wrong, some dont. My dads still has the originals from 99 and they work great. We know the stator is probably the problem.

No money for VF3 reeds

I cant wait to get the stator.

My name on BHQ is bansheeb0y5505 and Im getting the parts from yam_fan i think.

Posted by: 400exrider989

thats fine, its your build do what you want, you'll see though, just trying to help out

i would just remove the TORS if you have them unplugged thats cool but it makes the throttle stiffer then without then , harder to jet, and dirt can easily get past the caps because they dont seal worth **** and its extra weight, best to get rid of it, dont want to get dirt in the engine because of stupid tors caps not sealing, bloody things

also i might have missed it but you should get the clamp on style filter from pro design, they save many engines lives, stock filters dont filter **** and they dont seal around the edga, like everything else

oh BTW im 350BANSHEE350 on bhq, i know i know very creative name

Still down to the frame. Polishing things right now, waiting on my motor to be finished, waiting for my frame to get here. So basically I can't do anything until I get those parts. And im not sure about the colours yet being as I am getting plastics painted by "theshee"....

HondaMaster, hopefully you figure out what is wrong with your shee. Generally they are pretty easy to diagnose and trouble shoot so good luck!

Posted by: Hondamaster5505

Yeah, we are gonna get rid of the TORS eventually, but its not at the top of our list.
Also, forgot to mention, the parking brake IS disconnected, and takin off.

And I have a question:
When you unplug the TORS system, do you have to jump out any wires to get spark? Just curious, because we just have everything unplugged, not jumped out.

Also, a change to the mods list:
Instead of SS bolts, im gonna buy the zinc coated bolt kit.

Posted by: 400exrider989

where did you unplugg the tors at? there is a small black box under the tank on the left side of the bike, if you unplug that then it will have spark if you dont then it wont, you need to unplug that and take it off beat it with a hammer, burn it, and beat it again and then throw it out LOL, yeah i like zinc coated bolts better then ss, but ss is nice too, anything that doesnt rust

good luck, yeah theshee is amazing , his polishing and plastic painting skills are really "booming" i love his stuff and he is a one in a million kinda guy

yeah dont you just love waiting for parts, looking out the window every 20 min to see if a brown truck comes around the corner, or do a lap around the house to make sure the driver didnt hide a nice box in the back! i love USPS deliveries!

imo the boost bottles are kinda nice because when i had my blaster i got one and it just evened out the throttle response so i didnt have the anoyying up/down throttle. but it did crack my intake manifold. the only reason why is it was a vitos one and its in such a wierd position plus the hose was almost bent at a 90 degree angle \ that it had alot of pressure on the manifold. but there are easy fixes to that. and by the way the reed spacer actually did give me more power it was worth the money to me. just my 2 cents

Was this on your Blaster or a Banshee that you used reed spacers on? Was it a seat of the pants increase in power, or did you dyno before and after? And did you have the reed spacer before or after the reed?

Posted by: fasterz69

it was on my blaster and it wasnt on a dyno i could just notice the power increase with the reed spacer and it was after i already had boyesen reeds. it was mounted before the reeds closest to the motor

Juist wanted to offer some axle berrings if ud like to refresh yours wile youre rebuilding (( or any of u other guys need a set))i have two new in box sets with seals one set is all balls the other is moose racing
they fit banchee and blaster

Actually, we could use them. The banshee was sitting in storage for 10 years before we picked it up.

ill talk to my dad.

UPDATE:

Traded my white fenders for a full exhaust- Toomey T5's. I figured id give them a shot on a decent running bike.

Replaced and checked everything, and we're almost 100% its the stator.
When we get another stator, and we get spark, tear-down shall begin

(Side note: If anyone has a working stator they can sell me, please shoot me a PM)

Posted by: Dinner

Soo any new pics or progress?

Once i get a stator, ill do another update with pics

Posted by: Hondamaster5505

UPDATE:

Bought a stator for $30 from a guy off BHQ. I think he either shipped it priority yesterday. Should be here by maybe tomorow/firday.

I'm going to install it and see what I get. Wish me luck

God I hope I get spark. If the stator doesn't do the trick, then im gonna say screw it, part it out, and buy a complete running banshee. lol.

Also, instead of completely tearing it down after we get spark, im making a little change.
If we get spark, we're going to rip the engine out, split the cases. Get new crank bearings, or possibly another crank, and re-seal the case properly. Then the cylinders are off to get a frest bore and wiesco pro-lite pistons.

Once the motor is 100%, were gonna throw it back in the frame, break it in, and then install the t5 pipes and tune it.

So, we're going to do a complete teardown when winter comes around again. For now, we;re gonna professionally paint the plastics i have, get the motor 100%, then ride it for the season. powercoating and such will be done over winter.

Posted by: Dinner

Who are you getting to paint your plastics? Are you getting a design done, or just certain colours?

We're doing the job ourselves

We're gonna do black so we can have the black fenders and gray tank/seat/radiator cover. I think it's look cool.

We're gonna sand the plastics, use laquer thinner, flex paint, etc. By using the flex paint, we dont have to worry as much about the plastics bending and chipping the paint.

Ill get some pics as it sits this weekend, then as we go through the motor and such.

Posted by: 400exrider989

dyno proven that reed spacers and boost battles decrease horspower and some rpms on the banshee, i think it gained .2 hp at 3000rpm and lost 500 rpm up top and lost 2 hp in the powerband

check it on bhq

Posted by: Hondamaster5505

!!!!!!!!!!!!!!!!!!!!!!!!!!!SHE'S ALIVE!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Okay. So we got the stator today. My dad brought it home with him, so we sat down and installed the whole set up. We were having bad thoughts, being the stator that was in the banshee looked to be better shape.

So, we installed it anyway, figuring, why not? We installed it, kicked her over, and...... HURRAY! She got a strong spark. It was the stator this whole time.

We got some fresh mixed gas, hooked everything up, and kicked her. After 2 kicks, she roared to life! After sitting 10 years without running!

Now, we had to shut it right off. The carbs are so screwed up from sitting, that one side wasn't getting fed, and the other was stuck wide-open, so it tried screaming. We're gonna pull the carbs off tomorow to try to straighten them out. Ill take it down the driveway then tear the engine out of her for the complete rebuild of it.

IM SO HAPPY
