hi
well it appears my new nsr is is need of a top end rebiuld as i can see some scratches on the piston and rings when looking up the exhaust port .so i really need some advise on how to go about it.my first question is can i remove the cylinders without removing the whole engine from the frame as you can on other bikes?what do i need to know about removing the power valves?do i just undo the cables or is there more to it?
i really would appreciate any advise you can give me as i would really like to get this thing on the road and enjoy the bike,just hope the cylinders are ok.
