This is my first post so go easy on me!
I have a 1971 Vespa 125 GTR with everything original except for a 12v conversion. I am going to be using the scooter for commuting and touring so am looking to increase the power. I am tempted by the Polini 177 cylinder kit, is it reasonably easy to fit? Also not sure what carb to fit with it? Would I also need to change the crankshaft, if so what is a good reasonably priced one?
I am going to buy a new exhaust and am thinking of getting the Sito PLUS will this work well with the Polini kit?
Any advice gratefully received.
