    dial-a-jet, does it really help?

    I read the previous threads and was asking myself, "ok so you have to lean out the carb and drill a hole in it for it to work, Why bother".

    Now how many of you put them on completely stock machines and never touched the jetting and saw a gain in performance? I'm especially talking about the utility trikes.

    If this thing acts like a fuel injection system i might buy it so when I change pipes and filters I dont have to worry about jetting. But what happens when it breaks ?

    this link will tell you everything you want to know. I had one on my tri-z and it worked great but now im running a different filter and carb setup so now it's not installed. Im not sure on how good they work on a 4 stroke though. I have one forsale if you want to buy one.

    If anyone can say that it works on a 4-stroke, and wheeliepop doesn't buy yours from you, I will probably buy it. I had to rejet my carb after putting on my Supertrapp, and then when it got cold I had to either rejet or take it from 12 discs to 4 or else it didn't have the power it usually does. Its a hassel. Anyone know of how it works on 4 strokes?

    It works very well.The performance mods i have done make it worth it.I have found 1 perfect setting for it.Throttle responce improved,power was a little noticable.The gas millage got alot better.It was already good enough.
    It was a little pricey.

    Is the snorkel required?
    And would the Tri-Z Dial-a-Jet fit the SX???

    So if I were to put 12 discs on my Supertrapp, take the airbox lid off, and ride it in the winter.. It would be fine? Thats awesome.

    Ok then. I'll just buy it. If it doesn't work on it, I can always re-sell it.
