Thanx for the compliments on the quad. Unfortunately, I wont be back from Iraq for a few more months, so getting some more pics will be a little tough. But with any luck, I'm gonna throw some paddles on it and try to get down to Little Sahara State Park in October. I added a pic of my kennels here in Balad, just for the hell of it.

The quad looks awesome. That's a big *** motor on there!
Take care over there...PB

Posted by: QIKLTR

absolutely awesome quad!! i would deffinately vote for it. how much modification was needed to mount the motor? it looks super clean and i cant really tell how it was done.

Posted by: rr outlaw

got my vote! Really nice quad.

Posted by: wunbadmp

The swingarm pivot-bolt mount is the only existing factory mount. Two tabs were welded to the upper section of the frame to accomodate the upper engine mount. Square tubing was added below the upper, rear shock mount. That, combined w/a removable bracket, accomodates the rear engine mount. The front tubes that support the 400ex's front engine mounts were shortened, shaved and relocated. The lower engine mounts were cut, smoothed, and replaced with a section of tubing to accomodate the 650R's lower engine mount. The factory oil tank mounts were replaced w/another section of tubing, w/ two 9/16 nuts welded to it, along with two rear tabs to accomodate the new oil tank. Two lower tabs were welded in place to accomodate the trx250r radiator. Also, the front, upper fuel tank mount has two 1" spacers welded on top in order to slightly raise the fuel tank and keep it from pinching the upper oil line that feeds the cylinder head.

Unfortunately, in order to kick start the bike, I have to remove the seat and the rear brake lever to get a full kick. It can be a bit of a nuissance. But in the end it's worth the wheelies on demand, the ablility to embarass your buddies on their 450's and raptor 700's, and all the double takes and rubber necks from complete strangers. I just can't wait to get it in the sand.

what sprocket sizes are you running on that? my swap should be done shortly.

Posted by: wunbadmp

I'm running 15-36 on 18" holeshots. It does great on tight trails and still screams down the logging roads. Sometime's I wonder if 5th will ever wind-out.

Posted by: wunbadmp

You should post some pics on here when you get it together.

Posted by: i_mangle_sht

i sure will, thanks for the reply.

Posted by: Caseys 300ex

That quad is bad *****$$$$$$$!!!!!!!!!!!!!!!!!

Posted by: wunbadmp

Thanx again for all the compliments. I'll be adding a thread for my quad in the QOTM poll. I'd def. appreciate any support.

Posted by: wunbadmp

The poll for the quad of the month is out. I would def appreciate any votes.

Posted by: pb_paulie_b

I voted for it

Posted by: wunbadmp

Much appreciated. I think I'm still hurting in the running though.

Posted by: pb_paulie_b

Yeah lots of people vote for the most blinged out looking quad. I like your because it does look nice and it's something you can't buy from a store.

Posted by: BamBamm13

Sorry I missed the vote.

Love the 650ex!!!

What did you do for an exhaust? What kind of oil tank did you use? Any fitment issues for the Carb and intake/airbox? No bodywork fitment issues after the spacer for the fuel tank? Thanks and the quad looks killer!

Posted by: wunbadmp

The exhaust is a Big Gun header and mid pipe w/a Barnumspro can. Not real sure on the brand of the oil tank, I found it on ebay. I run Maier front plastic, which comes with adjustable mounting brackets, so fitting the front plastic is tight, but comes together fine. The steering stem does make some minor contact with the fuel tank cover when I turn the bars to the far left or right, but it's not a problem. I use an aftermarket aluminum airbox that has the same geometry as the OEM airbox. To get the carb to meet with intake tube, I used a section of rubber hose (similar to what you would use on the plumbing for a turbo) with a small piece of exhaust tubing (to clamp the two tubes down to). If you got to: http://sandbros.com/v/sandbrosmembe...38_001.JPG.html

you can elarge the image and get a closer look at the carb fitment. Thanx for the compliments.

Honda is actually working on mass producing a 650 sport quad. They are talking the XR650 motor and putting it in a sport quad so it looks like your ahead of the game here. Its gotta be crazy fast! Looks awesome too

Posted by: tayyo789

estimated hp? im thinking of starting one of these builds and am accepting any help and info i can get

Posted by: wunbadmp

I have no idea on the HP. As much as I'd like to put it on a chasis dyno, I don't know of one around here. But to give you an idea; a friend of mine has a YFZ450 and another has a Raptor 700. The 450 has a K&N and a Two Brothers header and can. The Raptor has a K&N and an MSR programmer with the pipe uncorked. Neither one of them (admittedly) holds a candle to the 650. The 450 doesn't even come close and Raptor just doesnt quite hang on either. If you have any more questions just give me a hollar.

Posted by: tayyo789

what kind of struggles did you encounter with the engine installment or alignment with the sprockets, etc.?

Posted by: racernorris

if you will give me your shipping address i will ship you a set of paddle tires, i don't use them, there for 8 in rims. and when you get back you can roost a little sand.
and thanks again!!!!!!!!!

I wish you would've shot me that message sooner. I just ordered some ITP Sand Stars off ebay a few days ago. But I definately appreciate the offer.

As for the front sprocket alignment, there was no issue with getting it aligned (amazingly). The easiest way to line it up is to mount the engine to the frame and swingarm, through the swingarm pivot bolt location. It should line up just fine.

Posted by: racernorris

have you got some front dune tire, i have 4 sets here that i will never sell or use, i would be proud to send you a set of those?

norris

Posted by: wunbadmp

Yeah, I only ordered rears, so I could definately use some fronts for when I ride at St. Joe State Park. I'd hate to see you absorb the cost of shipping though.

Posted by: racernorris

pm ur address and don't worry about the shipping....

thank you
norris

Posted by: wunbadmp

Yeah, I could definately use some fronts if you dont mind sending them out to me. My address is:

152 Ellis St.
Ft. Leonard Wood, MO 65473

Thanks

Posted by: 450racers.com

That is one sick quad. Looks like a very professional and clean build as well.

Posted by: wunbadmp

Thanks.

Posted by: Rippin450R

I wanna buy this thing from you! I love it!

Posted by: wunbadmp

racernorris,

Got those tires today. Much appreciated. I'll post some pics of my next trip to St. Joe's. Let me know if I owe you anything.

Rippin450R,

Sorry, it's my baby and I don't think I could bring myself to sell it. It's too much fun to ride and great conversation piece when I take it out. It's a pretty easy build if you're interested.

Posted by: Rippin450R

Im very very interested in that build! Id like to def know more about it

Posted by: racernorris

keep the plastic up and th rubber down!!!!!!

norris

Posted by: wunbadmp

I'll do my best. That CRF conversion you got is pretty mean lookin.

Posted by: wunbadmp

Rippin450R,

If you look at the first page of this thread, there's an entry i placed for another guy interested in a similar build. It has pretty much all of the 400ex frame modifications listed in it.

Posted by: RoadRidin450r

Thats a really nice quad. I wish the new honda 700 looked similar to that insted of that thing they made. If you dont mind me asking what kind of suspension is being used and why is the ride height look like it cant get any taller?

Posted by: wunbadmp

The ride height is actually pretty tall when you see it in person. I'ts similar to stock height. The suspension is a set of Marvin Shaw coilovers. They look nice but they don't perform that well. I'll be scraping them for a set of Elka or Fox floaters in the future.

Posted by: RoadRidin450r

Oh alright I never heard of those shocks before even though you mentioned it is about as tall as stock it looks alot taller then stock. Maybe your shocks need adjusted or something but yea new ones would make it really nice.

Posted by: wunbadmp

Here's some pics from St. Joe's from last weekend. Just follow the link. Thanks again for the front tires.
