I have a Birky built 131 w/Buller Duals, and was wondering what I had to do to make it a 150cc. I know it has to be bored, but what piston do I need to use and is it worth the extra effort. Does the temp become more touchy to maintain or about the same. Does it effect the durability off the engine,, or would something like a 141cc be better , or go on too the 150cc.
Opinions, ideas, and advice would all be much appreciated or any other direction worth going!
Thanks Stephen#24
