BansheeDan Posted July 18, 2008 Report Posted July 18, 2008 anyone?? also i brought the cylinders and pistons to an engine shop. the tech told me it looked like an over heating problem??? im runnin a cool head with a billet impeller also.. soo im stumped but i would like to know what i that rubber piece or quare plug is, at the bottom of the cylinder..... that rubber piece is the cylinder seal... it goes in the waterjacket in the bottom of each cylinder. if they are not there trust me the cyls will leak out of the base gasket,been there done that. if that seal was out of place it could let coolant in to the crankcase which would explain the overheating problem.

monster_energy06 Posted July 18, 2008 Author Report Posted July 18, 2008 uh??? well i gess thats what happend... first time i take off the jugs on this thing ..the bike has been running like this for over 2 years since the rebuild, wen my buddy had it.... the damn rubber piece is almost pushed all the way in..???? could my shee have survived that long with that piece pushed in?? cuz i have been riding this thing all the time since i bought it ....... or could somethign have caused this piece to push it self in?? sounds impossible really..... its bolted right down to the base gasket and right to the crank case??? tx for the info BansheeDan.. i wasnt really sure what that piece did but i kinda thought about it but wasnt sure...
