Vibration? Is my engine going to die??!!

[Skeldaw]

Hello, I noticed that my 400ex vibrate just a little on the peg ( Thing that you put the foot on that I dont know the name in english ),But not a big vibration that hurt on foot/hand. Is it normal? I have a oversized piston (402), Is it because of that ?

Check all motor mounts and the pegs before anything else.

Mine vibrates so bad your hands go numb, its the engine.

No me it's not that bad, It's just a little vibration at the pegs, And it's only at certain RPM, Not a idle or anything

Then Id check all the bolts and make sure they are tight, specially the pegs.
