2003 650 Piston. Which one???

ArdsBerg · May 13, 2015

Hello all,

I am looking for a high compression piston for my 650, wossner?

I know you can get a 2mm dish, 1mm dish Tall Boy or a flat top, which is going to be best for my bike

Regards
Stephen

If you have a 644cc motor (2003 shud be 644 unless sombody has already installed a pork chop crank which will make it a 628) then the best piston for the job is a standard compression piston due to the inherint weakness of the crank.
if you already have the updated crank then more compression is good.
