Not my work but kind of interesting.

Hmm, the transferports on the left and right arn't that big. Only the transferchannels are big. I dont think that it will make a big difference.
I think the upper transfer ports make the biggest difference in performance

living on the edge!

curious if it'll break or not, so thin on the sides
also I think the pistonrings will have a hard time with the topports,
looks like the hallway goes way lower than the rings

hardly any place for the gasket

I wonder if/how it runs


EDIT: it also needs some crankcasings to fit with it, wich may cause some problems

is this gonna be fitted on the "notso-special"?

Not sure yet may have to get some weld along the bottom edges and start again, this came from the guy in the U.S who gets 85mph out of his 73cc G7s so would be nice to try it but my cases are already on trhe limit.
