I tried to make this work on my kinetic tfr and could not get it to perform. Up for sale vespa malossi 43mm 64cc cylinder kit - 12 pin - ciao head.
This sells for over $135 at treats. All you need is the case gasket. I can throw in three main jets too. pm me if interested. Of coarse I'll sell it for less, still in like new condition.
