I am actually driving with this config :
102 DR kit with 19/19 reed valve, 2.86 Primary and polini banana exhaust .
When we are 2 on the vespa, it's fuckin' slow and it takes 30second to go to 40 km/h.
I want to get more power but without opening the engine .
I am hesitating between 115 Polini kit and 112 Malossi . It's for a city daily use and small week ends travels .
Wich one should i choose ? Thanks
