Your scooter is running a little quieter, it would be interesting to know what the speed is on the propeller. I had a camera mounted on the body above the engine, so all the vibrations are felt stronger and the speed on the propeller is approximately 2800. If your scooter has a manual, read it
Not listed in the manual but I doubt it's above 1000rpm. I should get an optical tach and check for fun sometime.
