my little brother bought a 89 suzuki rm 250 and i had pretty much no compression. so i figured we will ring it and it will be ok. well that is not the case. :bang: the dude that had the bike before put the piston in wrong so the rings gouged the hell out of the cylinder wall and the piston. well the cylinder has never been bored out. so i dont really think that we should bore it and have it chromed. the shop told us 400 dollars. do any of you guys know where i can get a cylinder either new or used and what years will work?
Check Eric Gorr's website. He has cylinders listed for the '89 RM250. If you don't want to buy a used one, then send your parts to his shop and have him look at the cylinder and decide what is the best coarse of action. He has done lots of work on my bikes and I will continue going to him for service as long as possible.
