yeah, i want something a little bigger than a 440 if i can find it.. but if i could find a 440 for a deecent price i would think about buying that.. is there any difference in power between the 04 440 pro XR motor and a 07 440 IQ motor?
Yes, the IQ is a stronger motor.
If you get another 440 you need to do the crank oiling mod. Search HCS for the "ripperd" mod. There's basically no such thing as a trail ridden 04 thats still on it's original, unfried, motor.
