Dial-A-Jet...

[Joel85350X]

Has anyone ever used the Thunder Products Incorporated "Dial-A-Jet" kit for their atv? It really sounds interesting. I will be putting everything back together on my 350X soon and I was somewhat concerned about jetting and carb tuning (I hate it). If it is as good as they say, I may not have to rejet my X after all. I am running a 352cc cylinder, a K&N Filter, and a Krome Power megaphone exhaust, and I don't think the stock jet will hold up. I had the pipe on before the rebuild, but it ran pretty hot and I think it was lean. Let me know what you think. They have a model specific for my trike.

This sounds like quite a good thing, the principal is there, I would think It'll be quite effective, I might consider getting one for my 110, $70 isn't too bad, if it stops you from melting your piston!

Thats what I was thinking. And if it doesn't quite solve you jetting blues, (too lean still) upgrade to the dual jet kit and have even more fuel atomized for the engine to use. I think it sounds like a great new idea, and the magazine reviews seem to like it, too. It is basically a mechanical fuel injection for a carb.

If you do buy it It'll be a much better investment than a "RoostBoost" (don't start this debate again people! They are useless) Remember if you put it on a trike you need to fit the snorkel Kit witch is another $10, unless you just ride on the road!

i believe dial a jet is a bunch of crap
there's no way a line coming from the floa bowl drain up to a little box on the carb.. will give it more response and increase performance

i dont see how it keeps you from rejetting... or how it works... or how it knows the amount of fuel to inject

will someone clarify this ???

[plkmonster2]

i think it works by how much fuel/ suction there is. if there is too much suction, i think it pulls fuel up the tube, but i wouldn't buy it, because if your airfilter becomes plugged, it will pull so much fuel that the engine will become hydrolocked -aka, too much fuel in the cylinder for the piston to turn over. that is worst case senario tho, most likely, it will flood and die.

[HypnotizeMindz]

yeah.. forget that.. i'd rather buy a bigger carb or just rejet it

[plkmonster2]

also, you must remeber that you have no bleed once you do that, and if your floats stick, and your intake valve is open, the gas has no way to get out of the carb, so it goes into the engine - flooding

I have a dial-a-jet on my 250r and have had no problems with it. As for hydrolocking your motor, it's not possible. It works on a priciple of vibration waves. It's hard to explain, but check out their website and read up on them more. It only adds fuel when it needs it. Another choice is tempa-flow, which uses temp of the air to create a vacuum in the float bowl only letting so much fuel go out of the main jet. Both systems work extremely well.

it's not that i dont believe you.... i just dont understand it....i read everything there is about it, maybe it's just something u have to have to understand it.. a trial and error thing

The way I unerstand it is that the air moving across the top of the tube in the carb siphons fuel through it. Just like every other circut in the carb. It uses different size holes on a dial you can turn. What I know it helps with is taking out lean spots mostly on two strokes. just by adding a small amount of atomized fuel. It was originally designed for snowmobiles. It installs in the drain plug on the bottom of the carb with a drill and fitting they supply. So you keep your overflow and wont cause the engine to flood out. I was thinking of getting one myself through work.

[Joel85350X]

Through work? Can you get a discount? Do I smell group purchase? :)

I am very seriously considering this product.

I've been using a tempa flow on my sled for the past 2 years, it works just like ski-doo's DPM except the tempa flow doesn't change for elevation. The benifit of using this on a sled is as the temp changes the tempa flow changes the vaccum pressure to make the sled run chrisp at 40 degrees or -20 with the same jetting. My mpg also increased.

[Joel85350X]

Evidently temperature change characteristics are what make the Dial-a-jet a good product. I think I am going to order one today.

[YTZ250N]

I could prolly work somthing out. We ship daily at the shop. We sell alot of stuff on ebay. We sell aftermarket and OEM parts and lots of Wiseco stuff from the store. Full service porting and cylinder boring.

[Joel85350X]

Private message me if you really think you can get a discount on the Dial-A-Jet. I am most certainly interested.

Also, if you deal with K&N I would be interested in getting a filter, too.
