What brand of pistons are they? Quote
uwenr Posted March 3, 2009 Report Posted March 3, 2009 m&h Dont know that brand how did you know what size to order Quote
banshee_terror_ Posted March 3, 2009 Author Report Posted March 3, 2009 Dont know that brand how did you know what size to order i read my piston tops. i thought they said .20 but i just looked at them after you said something and they say .020 so i just read my old ones wrong but thanks Quote
sleeper06 Posted March 4, 2009 Report Posted March 4, 2009 You can also measure your cylinders with a mic 64mm=stock 64.25mm=.010over 64.50mm=.020over and so on be sure of what you order,also check piston to cylinder clearance,too lose is no good .003-.004 is good anything after that gets noisy runnable in somecases but will affect piston life due to moving in bore to much Quote
