82cc "Hoca BBK" on '13 TaoTao Upgrades and Help

[ShotnVA777]

Here's my mods.... as of right now! Anything that has a "*", is already done. Anything that has a "-" hasn't been done YET. Anything that has an "X" will NOT be done!!!

I'm running around 43-45mph (GPS Verified)... It's pretty quick up to about 30-35, but then takes a few to get up to "TOP SPEED". Who can help me get to 50mph?!?!

2013 TaoTao 50cc Scooter

Mod List:

* Hoca 50mm (82cc) Big Bore Kit
* Hoca Performance Head
- Cheap, Digital RPM Gauge (7500RPMS MAX!)
* Lighter Performance Cooling Fan
- Kevlar Belt
- Performance roller weights (5 g's in stock variator now - Buy Roller Tuning Kit - 5 & 7's seem "average" for a BBK)
* Performance carb (Jet Size(s)?)
- Carburetor Main Jet Tuning Kit (#88 Main Jet "recommended" for BBK)
* Direct air intake (Add hose for CAI)
- Iridium spark plug
* Performance CDI (Moved "trigger pick-up" to advance timing curve)
- Performance coil (Ground directly to engine block instead of through the wiring harness)
- Performance exhaust (port and polish stock pipe, check exhaust port for any blockage and modify muffler or swap for "Briggs and Stratton Sausage Muffler")
- 1.5k RPM Clutch Spring(s)
- Shave drive boss down to 36mm(+-) (AFTER CHECKING RPM's and PERFORMANCE!)

What y'all think about the 5 gram rollers? I'm about 185-90 lbs and it averages about 43mph. Do I need heavier weights and also what size Clutch SPRINGS and what size MAIN Clutch SPRING?
