Hello. I am interested in racing next spring but am not sure of what type of racing I want to do. Can someone explain what should be done to a stock yfz if a person wanted to race motocross, crosscountry or TT? Thanks for the help.

You could pretty much do whatever you want to for any type of racing. From a XC (cross country) standpoint. Skidplates all the way around and then I would definitely get the rear shock re-valved and re-sprung. It's way to stiff. I think Yamaha loaded it up with Viagra before they left the plant :D Itp XCR tires all around. Handlebars would be my next option with a longer steering stem. You can buy an aftermarket one or get a OEM (stock) Raptor one. It's right at 1" longer than the stock YFZ one. Then I would get a steering stabilizer. The front end is a little wide if you race "Mid South" harescrambles but for the GNCC's I think it should be fine. The front shocks seem to be OK for the woods. Just take all the pre-load out and it'll ride much better. I would do all of these things before I would worry about the motor. The YFZ has plenty of power all ready and if you're just starting to race, it can be a handfull in the woods!! :O Now if you really want superb handling and kick ass power. Just throw the air box lid in the trash, add a KN style filter, re-jet!!!, get a aftermarket pipe and hold the Frick on!!!!!! Get a weight for the flywheel or try an aftermarket one for the really tight stuff. Get yourself some ArsFx a-arms (you'll need some 4+1 offset wheels for these and long travel Axis, Elka, TCS or PEP shocks all the way around. That's pretty much it! This thing rocks right out of the box! and lookie there, I'm a poet and didn't know it :lol :lol

any suggestions on a aftermarket flywheel weight/ and how much of a job is it to change one. i just bought mine 2 days ago and i race in the wnyoa harescramble series(super tight tracks) and the gncc's. any help would be great.
btw,thanks for the heads up on the raptor stem. i have a burgard =1 stem on my raptor i think i'll try. :D

Trailtech is supposed to be making a second run of these (flywheel). You'll have to get a flywheel puller also, or have a dealer do. I'd get the puller and the manual for the YFZ and do it myself. Then you have the puller and it'll probably be a little cheaper. My mechanic is currently working on some weights for the stock one but it'll be a couple of months probably. Also, make sure your idle is at or a little above the stock setting, which I believe is 1700 rpm's. I've got mine around 1800 and it helps. Get ready to work the clutch in the tight stuff! O yeah, what is wynoa? We've got a race tommorrow and I can't sleep. Just got AXIS all the way around! The rear one is soooooooo plush!! It definitely lowers the ride height.

Hmmm, I agree and disagree with some of the recommendations for xc, first of I had no problems killing the engine, its set slightly above stock. The tire recommendation also differs, I would use xc fronts in 22" size, the ground clearance and ability to soak up bigger ruts/bumps is worth what they lack in looks, the new xcr front push horribly in the mud, and have to hard of a sidewall so they ride like w00ter. If you a tall rider 6'ft range get a stem and good set of bars. Wheels from the factory are better than aftermarket red labels or itp's, but i would get a reinforced wheel, or beadlocks if they are in your budget. If your having trouble in tight woods, drop the front sprocket one tooth and that should help. Skidplates are a must at least on the rear, the belly skid holds up well, and a-arm skids might be a good idea since the stock a-arms are make from wok metal.

ricky stator tierods and ends are a must for any yamaha quad that is racing in the woods. i had them on my raptor and now will be using them on my yfz.

fly wheel weights make it so it dont stall so damn much a slow tight trails , plus cummin up over jumps it wont stall either, but i find if u run the clutch just right it dont stall, just adjust to how the yfz is, oonce u get it youll be fine..just my.02 im no pro!!! :rock :yfz

Asher,
You are right. Learning the clutch is cheaper! I've gotten better at it myself. Practice, practice, practice! The flywheel would just be my preference. It'll save on the clutch plates, also it will help with that hard neck breaking hit the motor has when you stab the throttle WFO in third gear!!! When I mentioned tight woods, I mean tight woods. Not GNCC tight but 1st and 2nd gear for over half the track. Hell, usually we have to run over trees on the first lap just to get through. Good luck on your choice man.

Thanks for the luck. I finished second in the ATV Sport Pro class. I got a bad start and was 8th off the line, zig zaged through a field and went in the woods 3rd. My buddy got the holeshot on a 86' 250R and kinda' checked out. It was bad dusty and the guy in front of me was stirring up so much dust I ran off the course four times on the first lap. Finally past him 1/2 way through the first lap but couldn't guy my buddy. He won on the holeshot. We had the same interval every lap. It's just a local series at Durhamtown Plantation (www.durhamtown.com) I finished 5th for the series and only raced half of the races! I love this Quad! What part of NY do you live in?
