Modern Vespa

I have a new Lx150 and when its up on the centerstand and the motor is running, the rear wheel spins. Is this normal? I would expect it to turn a little and with barely any torque. But mine spins pretty good and there is definity some power behind the wheel. It has been to the dealer twice for fast idle / hard start issues that have not been resolved yet. It is going back yet again tomorrow. Thanks for any info.

Have you ever overfilled the gas tank?

It shouldn't spin too much, just a few RPM's. Make sure your throttle isn't sticking. This happened to us a few times, then I noticed that it would only occur when I was squeezing the front brake then hitting the starter. If I did it this way I was inadvertently applying some throttle.

I switched to holding the rear brake and it stopped happening. Make sense?
