Scooter slow

[3lie]

I have a 79cc 2024 4t 4v typhoon I’ve basically done every modification I can to I changed the cylinder the cam shaft the variater even my gears and more and stock the scooter goes 65khm max and even with all the modification I’m only topping out at 72kmh the acceleration is fast tho but it’s not what I wanted idk what else to do the only
Things I haven’t done is change the air filter and jets and my carb. I’ve also changed my cdi and when I get to 72 km hour It like lags like it’s being restricted can some one help please.

You might need a longer gear set. Some only give you a 5% increase.
I would also check that it really is an unrestricted CDI. Do you have a tachometer?

Sell it anb buy a bigger machine. Just a suggestion when you have done about all you can and are not satisfied with the resulting performance. If you are maxing out rpms and not going fast enough, the only thing left is a final drive gearbox change to get longer legs. That will give your accelertion a big heaping of Slow Down, so it will not be as fast getting there. It's a tradeoff.
