A four stroke motor doesn't respond as well as two stroke motor to mods. I'm surprised it got the horespower it did with out a jet kit or dyno jet kit.

 

why don't we just keep the airfilter thats in it or just by one for the hell of it. This is gettin old.

 

Here is some more food for thought:
[ol][*]TORS - Throttle OveRide System - kills ignition if throttle sticks. [*]Banshee rev limit-13000rpm- turbo banshee research confirmed this limit(I had no idea it was there) When "hit" ignition shuts down completely and does not resume until engine slows down to around 3000rpm. [*]38hp for the stock raptor is low for it's cc's
and technology (the yz426 makes 45-50hp). Quads are historically detuned so the claims by CT may not be all that far fetched.
