I pulled my topend today to do a topend job. When looking at top of the piston I noticed a piece of the piston missing between the ring and the top of the piston. It looks as it has been this way for a while, carbon build up ect., like it hit the variable exhaust or something and broke off. Vissual inspection of bottom end appears to be in great shape, but I am some what concerned about this. Any ideas or comments will be greatly appriciated. Should I pull bottom end and have rebuilt or put it back together with new top end?
