Check to see if the drive variator has been changed to a de-restricted one. The drive boss should be smooth and not have a washer on it. See the attached drawing the boss is part 22105.

Hey!

It may or may not be restricted by CDI, de-restricting usually requires cutting a wire, unplugging a wire or cutting a back side of CDI off with hacksaw...
Where are you located? I'm guessing you have a DC ignition and I have Naraku derestricted CDI for Yup/Dink/People, bought it for my Super9 but it has AC ignition so it didn't work.

I've seen a washer welded into exhaust near the motor acting as restrictor, but I can't remember what scooter it was.

Also as mentioned above Variator may be restricted, some have a ring that is removed, mine had a whole sleeve that I ended up replacing because it has a shoulder on it that keeps it from moving all the way in.

Also ALL CAPS no bueno
