[QUOTE="astroboy, post: 372901, member: 4527"] Alo! Your piston is not rubbing the cylinder sleeve la. Its the piston ring in between that's soak up all the friction and to keep the gap sealed preventing crank case oil from splashing up into the combustion chamber. The new piston rings need to seat in properly and the process is called "run-in" or "break-in" .. :D [/QUOTE]
