Alright, so my bike is a ripper, but it has low enough miles that the bottom end doesnt have to cracked. thing is, its got a stock crank with the brass bushing. I remember reading a post a while back with some dude who put a 12x12x15 needle bearing in the piston end of the conrod. is this possible? i've heard the bushing is a bitch to get out, and when you finally do, the needle bearing wont fit. help save me my engine, and about 150 bucks
