It depends on the market. Where are you and how fast is it going now?

I am in Vancouver Canada.
top speed is about 65 km/h on a straight, downhill goes up to 70km/h and keeps cutting out, seems like wants to go little faster but CDi is cutting out the RPM - I am assuming is the CDi.

With the speed you are getting, the scooter isn't restricted. But if you are hitting the rev limiter, you can either get a cdi with a higher limiter, or try slightly heavier rollers to carry the belt higher before the limiter kicks in. Take the variator apart and see if the belt is riding at the top. You can paint the variator face with a sharpie, then ride it around a bit. It doesn't matter if it occasionally goes to the top, what you are looking for is where it usually rides when you are at full throttle, and you will see more wear of the color off the plate there. If it's not right at or close to the top, heavier weights might get you a few mph. But it's an air cooled four stroke, and in the real world, they don't go much faster than 40 mph.
