Modern Vespa

Hello there good people. The sun has finally reached Sweden so its time to get my vespa parts ordered. I just wanted to get some opinions on my set up before I go and order parts. Here is what I am running.


Vespa 50N from 1967 or around there according to the frame number, engine number has a different number. (but all in all pretty slow)

I have:

DR75 kit
16/16 Carb and manifold
Polini banana exhaust
Gearing 3.27 (22/72) Wouldnt mind getting some opinions on this. I know im not going to break speed records with this bike but trying to optimise it
Crank: Mazzuccelli 87mm Conrod (conrod is bent so I will be buying a new crank, was going to buy the same but if there are better ones out there for similar price)

Wheels: Thinking of replacing the existing 9" with some 10"


Thats basically it, any other tips of squeezing an extra km/h out of it are of course more than welcome

Thanks people

Sorry slight edit, i just measured the cylinder bore and its 50mm so its a DR85 not a 75.

Cheers
