I just purchased a new P500... I'm wondering if there is anyway to increase the engine performance and make it a bit faster. 40mph seems to be tops and at that speed it wants to force you to slow down with some kind of rev limiter... Just wondering.... I love its size and the fact that I can take it on almost all of the trails here in Michigan... And that's why I purchased it instead of the P1000...But would love to go just a bit faster
