I need to know the ring gap for a 250 (mid 80's) Bultaco Sherpa. If no one knows, is there a general rule of thumb of gap according to diameter of piston

I thank you Gents

Cheers Kev. Used the same ratio when I machined a Golf Diesel piston for a 4 stroke bike.

I've spent an amusing afternoon plugging the crankpin and padding the cases
