does the airbox have any restrictions? Or in the carburetor?
...dunno about your specific airbox, but yeah, some of them do...
..it's a disc, that can be removed...there's pics of it somewhere in th' forum....
..the restriction that's in your carb is the main jet...
..with a race cdi, and an aftermarket exhaust....you should be around 90, i'd bet...
..get rid of that airbox, and install a free flow, K&N type filter, and you would probably need to be around 95...
..that would open your scoot up, and you would get better performance overall...
..from acceleration all the way up to top speed...
..with good cvt tuning....
