[Fot] 89MM piston question

Bob, 
It is definitely necessary to make that modification to the liners. The relieve 
should correspond to the shape of the combustion chambers : about 4 mm wide on 
a 89mm engine.

Do the guys running the 89MM pistons and liners need to relieve the liners to 
clear the intake valve, or does the extra MM make the difference?
