I need piston rings for my Sachs, and all I can find are the ones with the FG ends. I need the ones with GI ends. Any sugestions?
The engine is the square jug, and the piston is 38mm, with a 1.5mm groove. The pin is centered in the groove, not offset.
The standard piston for the sachs motor is supposed to have a 2mm groove.
Would filing a bit off the end of the ring harm anything?
Should I try to file the pin in the piston groove?
