Weird? Scooter bogs at mid even with multiple main jet changes

Wassup everyone!

This really has me confused! My scooter sat for too long and I had to replace the carb...easy. Then I decided to change the air filter and rejet but now the scooter is acting crazy.

The scooter starts fine, idles fine but is crappy after mid throttle. Original carb had a main jet of 107. I switched to 120, 125 and 130 and with each jet (including 107) it sounded exactly the same as the video (below). Spark plug is black so I think I'm running rich?? But why?? With the new air filter I thought I needed a larger jet??

Hmmm any information would be awesome!

Thanks guys
