So what I have done so far.
Replaced Boss
Replaced Variator with Polini high speed (using stock smooth boss) and 6.9 gram rollers
Replaced original 80 jet with 82 jet (this came with the scooter when I purchased it)
Replaced stock exhaust with Technigas Silent Pro
Removed washer from intake valve.
What I noticed from test run.
Better acceleration, holding 37 mph on flats (was a quick test ride so motor never got warm)
I was getting a popping noise before I took the washer out. When driving it with that I did hit 43.5mph on a down hill
Next I am going to try a lighter roller, maybe 6 or 6.5 grams
