ok took my quad apart after a miss hap anyways a part of the piston was cracked and broken off some where into crankcase
so know im wondering if i have bottom end damage( the quad ran low on oil ) maybe im being stupid asking this question
but is it safe to just rebuild top end or just take the bottom apart
and inspect it since im halfway there , any one know , how to make sure main bearing is ok , reason i ask is cause the piston is aluminum and get more than likely got smashed ????? help
i have problems
