I believe they're around $10 each so cheap?..yes

I got a couple of rings from Bowman for an SF46. Super service, replied to my emails real quick. Rings were perfect, did not have do any gapping. I've only used 1 of the rings so far. He included a list of all the rings he has specs for, which was a very long list. And yes, if provided the piston and cylinder he can custom make them. I think it was $20 shipped for the 2. A very fair price for a quality product, in my book anyway.

This is evident, especially with many four strokes when it is just rich of peak, yet smokes like a carton of Camels. The plug is too hot and the mixture must be set rich to quinch the plug to get the peak RPM for that plug, fuel, compression ration combo.

Dang !! What did I do with that 50 SF ? [X(]

OK, so I was wrong about the price.[:'(] It's been a long time since I saw the info.
