what i would do is put in new frnt and rear bearings and check rod for slop and send piston and sleeve to rex welch (22racer) for pinch to be done or you can send him whole motor and he can go thru it . i think brian (mugen46) at pro twister mods is doing engine rebuilds also and has the bearings . i sent 2 motors to rex and they run AWESOME after fresh pinch thnx will g
