i have a 2001 raptor 660. not much done to it other then lrd pro 4 series full exhaust, k&n filter, geared down on front sprocket. anyways i been looking at other things to buy for it and ive come across this rev box cdi. says it bumps the rev limitor up to 10,600 rpms, few diff timing curves, better throttle response, and all that. my question is is this cdi worth the money and will i notice any difference in how it runs. also do i have anything to worry about with the motor being able to twist that high of a rpm? any info would help me out. thanks

 

Spend the money elsewhere, you're nowhere near the state of tune you'd need for it to be worthwhile. I'd be saving up for a new trans, rod, and one-way clutch and gear though.

 

thanks i was just wondering what afew people thought. i dont really want to go into the motor and start doin anything to it until it needs it. when it does i think im gunna end up going with the 686 kit and while im in the motor ill replace that weak second gear that i been hearing is a problem on the 01's
