wheel shake

[sleeper06]

This is the first time I have ever experienced this with american racers, I know the tires are growing but how do I fix it? It was smooth from launch thru 4th then just about to click 5th started to death wobble. Im thinking of high speed balancing or more air. Tires are ar 20.5/10/10 . This was with 7psi and no clutch tune yet it was maidin voyage. It spun tires for about 15ft. As it is . I can get the clutch to handle that but the wobble is terrible

Did someone put slime in tire?

Axle isnt bent is it?

Wheels been drilled to fit yamaha?

No slime all brand new shit , meant for yamaha, now the axle im not sure of but I have had many bad axles come thru, this is def a wheel shake issue , goes back n forth side to side. Does anyone know acceptible runout on an axle? Yes rob this shit was fast it will toast my bike on alky

We bubble balance ours, most take a lot of weight to get them balanced.

Yep, American Racers are usually way out of balance. Bubble balance using stick on weights and they'll be smooth as silk.

I guess ive been lucky all these years thnks guys, this is a customers bike first real ride, everything was flawless didnt even have to change a jet ran perfect. I gotta do a lil clutch tuning to make it more user friendly and I might have to put a steering stabilizer in it for him

[sleeper06]

Thnks again for all responses

That big of tire also compounds the problem.

Def not my first choice of sizes but tires were bought off a part out at a killer price I would of liked 19/8/10 but is what it is

Who can balance the smaller tire/wheels? I need a set of tires balanced and the folks at the bell tire might as well told me to go stick my mini tires where the sun don't shine.

We have a smaller Snap-on wheel balancer we do the ATV and motorcycle wheels with.

My local guy stuck them rite on his road force balancer , put a lil pressure on em, checked rim runout . He had to use a bunch of diffrent spacers to get er sitting rite but worked great, as soon as it stops raining here ill report back
