After riding my buds 450 now for several weeks, the biggest diff. I think is just how fast it revs. I love it but yet I hate to spend 10/12,000.00 to get it race ready, which my raptor is. How can you make the Raptor rev faster in short bursts like the 450. I have a nine mile track and I can run about 45sec. per lap faster on the 450 and I think I would attribute that to immediate reving which equates to being able to get to top speed much faster. I haven't done any motor mods on the raptor. What can I do?

Thank's

 

lighten the flywheel.

 

The 450 has less rotating mass and lower geared than a rappy. Maybe gear down a bit, you have a high rev cam and that kinda stuff right?
