polini still do a 2 port 177cc kit i think for the sprint/supers , depending on age an origin of cases some can be altered to take other 3 port kits. theres not enough ali on older italian cases to open them up to a degree were it would be worth it .very late italian's an piaggio/lml ,lml an baja cases are thicker ali an can have a 3rd transfer port carved into them .
with the polini 177 kit you can just unbolt head an barrel ,switch pistons an put new barrel head on a away ya go, but to get most out of kit it needs to be matched to cases an set up right .change carbs from the 20/17 to a 20/20 an re-jet to suit the kit.and get a decent exhaust like the sip road2 at least .H
