Hey guys, I have a question for you. When I was installing my Dyno Jet kit I ran into a problem. Well here goes...When I took the blck plastic slide out of the top of the carb to replace the needle with the one in the kit everything was good. But when I went to put the gray plastic piece that the little spring sits under back into it's place, one of the little black progs broke off. There is now only 3 of those prongs holding that little gray piece. The only thing I can think of is that the cold must have made it brittle to break so easily. Do you guys think it will be alright through some hard riding or will it pop out and give me trouble out on the trail? By the way, I ended up using a small pair of vice grips to get the phillips head screws loose because they were too tight.

 

Does the gray piece still snap in? ie. I have to use needle nose to insert it and remove it when I make adjustments to the needle. If it still is secure and snaps in with the remaining prongs you may be okay for a while. You still have the long spring that applies downward pressure on the gray piece so it shouldn't go any where, unless the prongs are not even slightly securing it. If you worried about being stranded somewhere, buy the piece of mind and get a new part.

 

Thanks for the reply Majorecho. Yes the plastic gray piece does still snap in, what I was afraid of though was that it might lean to the side missing the prong that holds it and eventually pop out. You are right about the spring giving the downward force, I totally forgot about that spring pushing on it. That jet kit did cure my bogging down problem in the snow. Now my DS throws one heck of a roost compared to before.

 

Yeah ,the kit made a big difference in bottom end & now I can p/u front end,never could before kit.

 

My experiance was very similar, once I piped and jetted the bike wheelies were a piece of cake, prior to those mods I had to clutch the crap out of the thing to get the front end up -and that was on asphalt! Now I've made some gearing changes ( taller front and rear) just to keep the bike from coming back over on me when I hook up too hard.
-quick story and then I'll end,
about 2 mos ago I went out to the Bonneville Salt flats with a friend of mine that has a 400ex, it had been about a year since we had ridden together. He had done some extensive mods to his bike and so he wanted to race me. I had never raced on the flats before and they looked fairly soft and loose, so I thought I'd be fine to gun the thing off the line(no clutch jus gas) anyway the next thing I knew I was on my back and my DS, still in 1st gear, was chasing after my buddies 400ex-gotta love that bike! So there I was in full riding gear running full tilt after my bike. I guess it's one of those things you'd have to have seen. My friend latter recounted he was ecstatic when by the time he hit 5th I still had not blown by him. He was a half mile away before he even turned around to see where I was. Needless to say that only happened once, but, in order to launch the bike off the line I still had to put all my weight from the waist up over the bars just to keep the bike from coming up too high . It was still lifting me and the front end up about 2 feet but I was getting one heck of a hole shot every time.
So I decided to gear up to broaden all the gears out a little- when you dial the DS in it is such a rush to ride!

 

Great story.
You have to love an ATV, That knows what to do, Even if your not behind the wheel.
