Engine vibration

Hi guys can anyone help? I have just bought a 95 dt125 and there seems to be a bad vibration on the engine that goes through the whole bike and it gets worst the higher you rev it.Im worried that the vibration will loosen bolts or break something has anybody got any ideas? Thanks Lee

Erm, not sure what to say mate... generally the engine does vibrate, just im guessing not as bad as your describing... :/ is your engine secured in properly? thatd be a good start. :) hope you get it sorted though.

all 2 stroke's vibrate mate....and it get's worst because most 2 stroke's dont have rev limiter's they just hit a flat spot in that gear! Which is why it get's worst....

I would'nt worry mate as long as there is no bad knocking noises or anything it should be fine biggrin
