squirly rear tire

10 posts in this topic

i just got my 99 yz400f running. first time on a big race four stroke and i notice that even on pavement(worse on dirt) that the bike tire goes a little squirly while accelerating. do i need to just deal with it or put more weight on the real wheel? any suggestions? i tried the search thing and didnt find anything. thanks

What tire? What pressure? What condition is the tire in?

Also check that the wheel is properly aligned.

new tire not sure what brand. when i put the tire on the side with the chain is a fraction of a fraction of a inch to far back. will that change anything? and do i want less pessure for more traction or what?

You have to much air pressure in the tire. Put only 12 psi in the tire and you should be fine. Run both front and rear tire at 12 psi.

Put the bike on a stand. Try to wiggle the rear tire back and fourth. If it wiggles then you need new bearings. If it doesnt then try what everyone else has said. My .2 cents.

Also try running a gear higher than your used to. It's not a 2 stroke so it will pull w/ torque rather than revs. :ride:
