pinning a piston?
I have a 25cc piston that I want to pin the ring so I can take the blockage out of the exhaust port. Can a stock ring be pinned? Anyone have close up pics of the process?

Yes Frank can do all that...but it sounds real easy to do it for myself. He is quite busy making piston rings now. I do not think adding a 2nd ring is going to help that much. Two rings will create more drag and cost twice as much I suspect. The aplication on certain engines, may make 2 rings worth it. Capt,n

I can't give you a perfect, "before, then after with no other changes" comparison, but it very definitely increases the power noticeably and is a very good modification to do. I do it to any Homelite 25cc I convert, whether it is for me or someone else....
