    I've heard that the piston rings on the 66cc are a little small to allow some blow by. Does anyone know of a replacement ring that's slightly larger? Or a piston and ring combo?

    the end gap is too large. any 47mm piston and ring combo with the right wrist pin height will work as long as the ring isn't chrome plated

    getting sizes in these is hard - just had a customer order a set & they were too large by just enough to bind the piston, had to file end gap a bit
