Hey guys, I think Im gonna go ahead and put a top end on my 03 yz450. It is all original inside. She still runs good and makes good power, but until it is warmed up, a blip of the throttle will give a little puff of blue smoke. Since it dosent do this if I leave the throttle alone for 1-2 minutes, Im assuming its the rings and not the valve guide seals, right? I figure I will redo it with OEM stuff from the TT store. I know I need rings, piston clip rings, a piston, and a headgasket. I'll do the cam chain at the same time. Anything else I need? Any tricks or words of wisdom before taking the plunge? Thanks alot guys!
