Dial-a-jet

[Jak400ex]

Anyone ever run a dial a jet system. I saw it in Rocky mountain atv. It says it's an external jetting system that's supposed to give you more fuel efficiency and less lag. Just wondering if anyone had any experience with the system. Good, bad, or ugly? It's 10 bucks more than a regular jet kit.

That would be Ugly from what I've read on several boards.

I recall you have to drill out a fitting passage in the float bowl or something for the kit to "re-circ" the mixture.

Good in theory, junk for pratical use. Another thing to break.

Guy tryed this in shifter karts CR125cc since modified 125cc are very picky on jets. He dyno'ed a dial a jet and regular Keihen carb with correct jetting. Stock Keihen had better performance.

Good way of blowing up your engine if you don't have EGT sensor and not familiar with reading plugs.

Thanks, that's what I hear.
