Hey mate, it was just a random 80-100cc 2 stroke exhaust from a wreckers. Cut and welded to suit. There are many people who do the style much better, with a better platform to begin with - look up 'bosozoku scooter' in google and you will be shocked!
I don't have the scooter anymore, but it ended up ...

I'm guessing the rider's weight would also contribute to the varying tuning factors!
So all the above in mind, I'm going to purchase the following:

#32-40 Pilot Jet kit
6g-17g Roller Tuning Kit

Once I've run some tests with the GPS and get some noticeable changes, I'll report back!
In the mean ...

The graph leans towards your roller weights being too heavy. Once the RPM’s reach a certain point, inertia forces the rollers outward and makes the variator pulley open/close creating a “gear shift” if you will. The RPM threshold this happens is determined by weight of rollers. Heavier rollers ...

Ok, so I've put the cover back on and will go for a ride / report back!

I will definitely look into the pilot jet and try downsize it ...

On my CP carbs, I notice this happening if I have the air filter cap off. Needs a bit of back pressure. And like Meatball said, smaller pilot. On mine with the 48mm BBK (68cc), they are both happy with a #36. I'd imagine yours would probably want around a #38 or possibly even the #36 as well ...

I went through all the cleaning and tuning steps, but was convinced there was an air ...
