I have searched and searched and cant find a actual answer for this. Is all i need to do is buy a new OEM cylinder and new OEM piston and rings slap it together and go or does the cylinder and piston need to be matched like we did with the old steel sleaved machines? I really do feel stupid asking this question. Iv built several engines but this plated stuff and all my options with plated cylinders im still behind the times. Please bring me up to speed a bit here. This is on a 2000 WR400.
