One way to look at it is to use the scooterhelp gear calculator to see what top speed to expect but changing only the clutch gear will decrease your speed.

Based on the calculator, now your stop speed with the p200 motor and 8 inch tires @ 6000 rpm is around 55mph. If you change the clutch gear to 21 teeth it goes down to 50mph and 20 teeth clutch gear is 48mph. Other teeth clutch gears will not fit.
If you open the motor you can put you vbb kick starter in there.

Are you sure about this?
DRT makes a 24 clutch gear cog that should fit the original 65.

I cannot calculate this in the calculator, since 24/65 is not an option in the calculator.
How much RPM does a broken-in P200E makes?
What's a confortable cruising RPM?
I was wondering how many MPH or KPH I would win at for example 5 or 6000 RPM by going from the standard 23 to a DRT 24 clutch gear cog.
Would the below be correct? Or utter b*llsh*t?
For example 23/65 is 55MPH at 6000 RPM.
20/65 is 48 MPH at 6000 RPM
What I did is=
23-20 = 3
55 - 48 = 7
3 tooth = 7 MPH.
So one tooth should be 2.33 MPH
So going from 23 to 24 would give 55 + 2.33 = 57.33?
I allready have a VBB kickstart

They now make them compatible to the PX kick start shaft.
