Who has thin rings for the early Mac pistons - 2.125?
I have a few STD, but really need .030

Terry,

A set of standard rings from any of the 100cc model engines will work with just a small trim of the ends.
Stock bore on the 7,8,9,30,40,45,90, 91 and after are all 2.165
If they are a little used that is even better.
If you can't find any let me know and I'll dig some nice used ones out of my inventory.

Steve,
Thanks - I'm gonna try hard to get the real thing. May have to take a suggestion to check with Otto's - he makes rings!
