You need to trim the thumb throttle so it can go full throttle I am too lazy to say where to trim but if you look hard enough I am sure you can figure it out. Also you can remove 4 balls out of the clutch(alot of people do 8 balls) also you can replace the Exhaust Cap/Spark Arrester with a non restricted one.

I trimmed the throttle lever plate today then did a test. 8.6 mph with the aftermarket procom cdi, 11.1 stock cdi. I started at 10.9 bone stock. It has zero top end right now with eiher cdi
