Hi,
I have a piaggio Fly50 2009 with a 80cc kit and the power cam from Malossi. I also have the Malossi Multivar 2000 variator with 6.1G rollers.
With my kit i drive over 1000 km and no problem.
The top speed is around 75~79 km\h (46~49 mph).

With the malossi kit i have, what is the best roller weight i need to install to have a better top speed?

Thank's

(p.s. i know my english is not very good because i speak french, i'm from Montreal!)
