How Far Will A Big Bore Zuma Go On A Tank Of Gas?

So I wanted to see how far she could go before being completely empty. Unfortunately the whole tank never gets used and there’s always a small puddle of gas in the tank but not enough to start it or let it run.
I have a Charmo Racing 75.6cc BBK in this scooter along with many other performance parts.
I also installed my Polini 66cc Fuel Pressure Regulator to give it more fuel and switched my Digital Fuel Tuner to give it and extra 28% fuel while driving. On a tank I can get 102 miles before needing to fill up again. And fill up was only 1.05 gallons. My area is mountainous so this was flat roads and hills.
A stock Zuma 50 (4T) could easily get 130+ MPG. This has the same engine as the Yamaha C3 (AKA Vox and Giggle)
Parts installed:
Charmo Racing 75.6cc Big Bore Kit

Beast Mode (Rolling Wrench) Fuel Tuner

Question: I had terrible removing the clutch cover where the transmission belt and varistor variator is located. I removed the plastic cover and I think 6 bolts but it was stuck. Is there any hidden bolts or do I just need to mallet the metal casing? Thanks, great video

2 stroke or 4 stroke?
