Make sure every bolt is tight with loctite  :-D

I heard one the other day ,cant remeber who but, fill you're bars with silicone to dampen the felt vibes.

Motorrad is right though balancing the crank is best, lighten up that piston & pin while youre there , so theres less weight causing vibes

I lightened the piston and pin in order to balance mine..  Sure beat adding weight to crank..

Also..   Pipe mounts need to be in good order.    Pipe needs fresh orings, and copper crush..  If jug is worn..  Some copper rtv also..   You wouldn't believe the vibes that can come off a poor mounted spanny

X2. a properly fitted pipe makes a drastic improvement, but a well balanced crank is the best bet.

to be honest with you ... to a certain extent they are going to vibrate anyway aren't they ?? will they ever be as subtle as say a kx250 ?
