I have an older motor, BM130 where the last time my dad ran it 33 years ago it shattered the top of the piston, cylinder, head, and crank are all good but I'm having hell finding anything related to this motor. All the spare pistons in storage are oversized and I can't find anyone in my area(yet) that still works on 2 strokes. The piston is stamped 56 but measures at 55.753mm. the closest spare I have measures at 56.032mm. Is there anyone who still makes pistons for these or what? I've been told that TKM pistons work as well but I can't seem to find the right one of them either. Another thing is I don't know the ring gap they ran on these, or what the side clearance was.

Is there anyone who still works on these out there?
