i just bought a 2004 660 raptor and was wondering if there is anyway to tame the low end power. i have 2 kids and i put around with them, and the 660 does not run good at slow speeds. it is all stock at this time.

thanks

I'm not too familiar with the raptor, but I would look to see if there is a throttle cable with some adjustment and maybe a stop screw.

The best and cost effective way would be to change the gearing. Its recommended to change the rear sprocket before the front. For every 3 teeth in the rear that is about the equivalance on one tooth in the front. to tame the low end you would use a smaller sprocket on the rear sprocket or larger in the front. If you want to significantly tame it down, go up one in the front and if not go more. Front sprockets only cost approx 30-50 bucks depending on the brand. But remember by doing this you are increasing the top end speed. On my banshee there is also a throttle limiter screw on the stock throttle housing when i had it on that you can turn in that restricts the allowable throttle, acts as a throttle block. I am not sure if the raptors have this.

A friend of mine has a 660 Raptor, his seems to work fine for putting around, although I always feel like I'm putting around when riding a 4-stroke. The power delivery seems smooth and very managable to me, it does like to wheelie alot though, taller gearing would definately help that.

there is an adjustment screw... screw it in and then they can only give it so much gas...
