am I wrong here? I thought you said the cylinder had already been re-sleeved by the past owner? is it sleeved or not? if not re-plate the darn thing. sorry I can't quote a price or that would be spam, and I can't say to call or thats spam also. but if your surfing around and you click the website button down there you might find a phone number on the site. also I just did a 97 CR250 cylinder that was trashed, blown crank & a broken piston, big rips in the cylinder walls, it was the worst cylinder I'd seen and that was $225.00 total cost to fix, welding, boring, diamond hone & shipping. if the cylinder has been sleeved then there no turning back. see ya!
