My buddy grabbed this moby for our nascent moped gang here in Toronto.
Anyway, he's not keen on doing much work to it (as you can see, it's in immaculate condition).
I'm having trouble identifying the engine. I believe it's an Isodyne, but I don't know where to find the identification on the engine. All I see is TUM-143.
Is it Isodyne? Super Isodyne? Could it be AV7?
The reason I ask is because we want to improve the speed of this thang. It's not the best. 40k on flats! The nice part is that he gets to bask in the glory of our four-man gang as he lags behind and gets occasionally honked at.
I'm not optimistic about making it any faster if it's an Isodyne. Can anything be done?
