Hey all, I have recently finished rebuilding my 1990 250R quadracer. For some reason, when i give it some throttle it shakes the steering to the point that it feels like my arms are going numb. I have checked all steering linkage to make sure it's tight, it was, and am clueless at this point. The motor was rebuilt with OEM parts, back to factory specs (OEM piston, rings, bearings, etc.), the only thing that isn't factory is the "hotrod" kit. I am not sure what is causing this excessive vibration and it is driving me nuts. Can anyone help me out?

 

sounds like somthin in the engine is out of balance. I put my crank balancer in the wrong way once and the machine shook so bad u could have used it as a dirt tamper lol.

 

Sounds like I am taking it back to the shop that rebuilt the motor for me. Thanks.

 

mine vibrated alot and i had my rear shock serviced and it went away

 

thanks it only vibrates bad while moving
