Fuck it. Do the Gila. If you can weld the cases or have access to having them welded and machined, then do it! You are gonna break a lot lot cluches. But you will get to learn how to fix them or make them better.
If your goal is to just have a bike to ride, then this path is gonna be frustrating to say the least. If you just wanna hot rod the heck out of a moped, then Gila that puppie up! Take chaces, make mistakes, get messy!
