Re: Noob attempts a Felt MP build: Have mercy on me.
Hope that Comet TAV-2 works out for you, but I'll be honest with you: I think that's too much gearbox for a Huasheng.
I remember reading about another member who tried bolting one to a Huasheng and it was said that the HS doesn't make enough torque. The TAV-2 is also not designed for the high RPM that a HS will run. You're also going to run a jackshaft, which incurs additional losses to the drivetrain. You obviously have the need for speed (a folly of a thing to have on a motorized bicycle, IMHO) but I feel your part choices are gonna let you down.
Just my thoughts. I really hope it works out to your liking, that's a beautiful bike!
