I was reading about these on www.thunderproducts.com and I also read about them in a recent mag. Anyone tried them yet on their Raptor? If so, what were the results?

 

Wouldn't this be a little complicated on the Raptor because there are 2 carbs, that have different jetting???

 

Apparently not, they sell a kit for the Raptor for around $130.00 or so. They sell kits for up to 4 cylinders. I think it was in last months ATV SPORT mag. It sounded pretty easy and inexpensive. No, changing jets. It has an externally mounted setup.

 

The multi-cylinder kits include a dial-a-jet for each carb.

 

The dial-a-jet leaned my raptor way out with a K&N and airbox lid flap cut out. It does make big changes in the jetting with a turn of the dial but since it leaned me out I'll probably have to increase my main jet size when I get a pipe.

Good product, not a miracle worker, @ss dyno tells me raptor seems to rev a little faster with a little more torque. Comes with 2 for both carbs. paid $130 + shipping.

 

According to what I read from reviews on their site(atv connection & motorcyclist magazine) the dial a jet richens the mix it adds atomized gas/air mix to carb. They said if you have a rich condition it want help, you need to get leaned out then the dial a jet does its thing sounded impressive.
