Has anyone had success using the dynojet kit on a 250ex. I have read for some time people complaining about it. I got one with a package deal for a t-4 slipon, K&N filter w/outerware, DynoJet kit, PRM front bumper, A-arm plates, modified air box lid, & moose shockcovers for $250 used, but in excellent condition. Personally, I wouldn't have got the dynojet, but the price was right, whether I use it or not.

The problem is with the needle. It's shorter than the stock needle, thin with no taper. In the short time I played around with it I have come to the conclusion that it won't work unless MAYBE I use the smallest mains they provide ( which is definately not what the instructions say ). As soon as it gets into the needle circuit it's instantly rich. Rich enough to foul plugs. I started with stage 2 instructions for no lid, and dropped 6 sizes before I gave up and put the stock needle back in with a oem 102mj.
I did a search on this and I know some of you know what I'm talking about.
Is it worth screwing with, or should i throw it in the trash? If I'd paid retail for this I'd be mad as ****.

You already figured it out, the new needle is too small for the quad. I tried and tried but never got it to run right with the dyno-jet needle. I ended up paying 40 bucks for one jet. Just use the jets and chuck the needle .
