Our mechanic just got done Dyno testing our shop 300. We dyno'd it in stock form, and also with combinations of Leo Vince exhaust, Super Corsa Racing Power Booster, and Polini variator.
None of the modifications were very good on paper (only a combined 1 horsepower difference), but we got huge gains in top speed. We were able to hit a legitimate GPS verified 91mph (100mph indicated) on the freeway versus the stock machine redlining at 82.5 mph. The scooter does have a Faco midsize windscreen which I'm sure helped freeway speeds.
The Polini variator made the best difference in power. We used the 6 roller version from the GTS250 but put in 12.9gr weights instead of the provided 11.8gr weights.
I'll post dyno charts later today when I get them from my mechanic.
