Hi all,
Guidance needed in fitting piston rings to my kitaco piston 75cc Honda c50 1974.
The piston kit included detailed instructions but all in Japanese.
My dilemma is with the two compression rings, one is dark grey and marked RN on one side(the top?). It appears to have 4 square edges.
The other is lighter grey with no markings(either way up?) and the edges are possibly slightly chamfered.
Any idea which ring goes where?
Thanks
Paul
