GY6 150CC Scooter Performance - 0-60 Time, 1/8th 1/4th Mile Time, Top Speed

[gmcjetpilot]

Does anyone have some data to see how I am doing. I recently tried for top speed and was disappointed at 50 mph. There are some reasons I can think of:
Lean Main jet too small
I have a big windscreen too much drag.
Still breaking in at 150 miles on OD.
