Can anybody tell me what exactly this is, how it works and what is does? I mean, the name kind of says it all...I think, but I just havent's seen it. Is it as easy at the east set fuel screw?

 

i dunno either sorry

 

My cuz has them on his shee. There really trick, I plan to get them.

Check em out

 

Go to www.thunderproducts.com. I've got them on both of my machines along with a few friends quads and we're all real pleased with them. I've got a set for a Raptor along with the jets if anyone is interested. I ordered them for a friend and he changed his mind. Brand new in the box.

 

Thanks for the info. Anybody installed one of these on a yfz450? Easy or a pain?

 

Would it increase top speed or acceleration on a Bruin 350 or not?

 

Has anyone ever installed them one a Big Bear?

We're planning a trip to the Rockies and I'd rather not have to rejet going and coming, but I don't want my quad to run badly either.

Will this solve my problem?

 

Dial-a-jet is to adjust jetting very easily. Tempature, altitude, and even humidity all effect how much "weight" is in the air. When it gets colder, the air gets thinner and when it gets hot or humid, the air gets thicker. For example, if the tempature drops and the air gets colder, then it thins out and more air gets suck in thru the filter with each crack of the throttle. This is why your jetting can be perfect one day and then off the next. When you install dial-a-jet you must lean out your mixture on the main jet which gives you movment on the dial. Then you can adjust it back to a perfect air fuel mixture, even tho the temp might change, you can use the dial to adjust the curve to be perfect at all times.
