will a stablizer stop my frontend from shaking at high speeds 100+ it does it when going over train tracks too at 30mph or so

 

If its just shaking that bad just going fast your probably have bent rotor or your front wheel isn't balanced correctly.

 

your suspension may also not be set up well.
with a properly set suspension, you'll get minimal head shakes. a damper shouldn't be used as a band aid for other problems.

 

well my rotor isnt bent. my rim is a little but it only shakes when im hard on the gas and the front end feels like it isfloating. but that doesnt explain why i get head shake going over the train tracks to fast

 

well, with a hard enough flick of the throttle you will make the front end come up. when you hit the gas real hard and your front feels like its floating its possible that you are popping a wheelies. i think you should just apply more weight to the handle bars and shift your position toward the tank.

 

what kind of bike?
