UPDATE: So after much speculation, we finally attempted to put this on a puch, and we are sad to report it is not an easy bolt on. It could be done, but the issue is in the raised portion on the bottom of the stator as it is larger then the indentation on puch cases. It could be done if you dremmeled the indentation off, but its not easy bolt on, bummer. That said, the bottom of the stator is plastic and easy to size to fit.
this cdi is sweet. easy to set, great construction and probably the coolest ground strap you'll ever find on a moped. This made my derbi/polini go pretty fast. Also can work on puch/others with slight modifications. Only downside is the spark plug wire is glued in and the connections have short wires, so you don't get a whole lot of mounting options.
