I think that's the same guy trying to sell one about a year ago, calling it an 80cc. I E-mailed then, asking the diameter, and yeah, 46mm. Big disappointment. Do you know if the bolt pattern of the other garelli kits (scooter/motorcycle) on Ebay.it line up with those of the mopeds? I've always been curious but haven't had the guts to actually buy one.
