Wiz I agree with you that is what they do. My line of thought was that they would not build a smaller version, so how would an individual go about doing it on his own?
I would probably snatch up something for a 80cc engine size range.
Heck I already have a Mike McConville designed bipe in the Midwest Super Stinker pitts bipe. Would love a larger all out ultimate bipe, I think, LoL.
