Welcome to a great forum! Only one guy on here has said he has changed the gearing on his scoot and that is Yager200i (that's his user name). I think he had them made and at great expense. You might have better luck with changing the belt to affect different ratios. It certainly would be cheaper. I think a longer belt makes the engine wind higher all other things remaining the same. I would think a longer belt would also limit the range of ratios.

I found a Malossi set 16/32 primary on this site including installation pictures. I did the swap myself with a homemade bottle jack press. The Malossi set is available from Racing Planet and probably many others in Europe. The gears are supposed to be 15% taller than stock. I am looking for dyno results from the Fabrizi 80cc cylinder; your horsepower figures for Polini and Malossi are informative.
