150cc piston spec
	
	
		Does anyone know the specs of the 150 piston for the rmr125 style bikes (size, gudgion pin sze etc..)? Is it possible to buy the pistons seperately? I ask because i would prefer to get my current barrel bored out instead of buying a 150 one, because i can get it done free at a freinds workshop.
thanks
