yeah, its so crazy, i was literally sketching this exact setup in class last week...
great minds think alike or something like that. i dont know what people are paying for these, but as they were saying in the 'av10' thread, its probably worth a good penny just because its balanced so well. its always a good idea to use somebody else's expensive engineering and mass production, i.e. sourching the scooter clutch parts.
i dont know exactly what gy6 stuff looks like, but it says TGB on the stamped clutch bell, and i know thats a pretty popular tiawaneese minarelli-clone.
its an awesome idea because you've got super cheap readily available shoes, springs, everything. I would assume they are using either the stock TGB shoes, or a preexisting TGB aftermarket part.
fucking brilliant, i cant believe it.
