Top end kit selected

I plan to make minimal mods to my TV175. The biggest one will be in the performance and reliability department. I am still researching my options, but I have pretty much settled on this set-up:

Casa Lambretta 186cc Kit
GP Crank
Dellorto 25 PHBL Carb
12V Elec Kit (may use Scooter's O)
Big Bore Exhaust
