my thing is, i think you need ALOT of clarification on jet sizes. IF they use the same size, then it makes perfect sense why you are running lean cause well that would mean a 126 is actually a 126.....I also don't understand why they say your setup is untuneable. It isn't that drastic of a chop on the can. Also he misinformed you a bit concerning the plugged hole, if my memory on theory of cv carbs is correct. The plugged hole will actually cause the slide to move slower. So it would stand to reason, to me, it would not be so much for "flutter". Unfortunately, I have not come across anyone with good luck using dj kits. All say something about stutter in midrange ability. May want to call factory pro, or someone similar just to bounce feedback off of them and see what they suggest. Way I see it, a phone call to competitors is cheaper then new header/pipe.

I see JNS got me lol. I was trying to figure out how to politely put the throw away the dynojet stuff lol.

I feel the same way, I think the dynojet stuff is junk

Yea I can remove the glue, but I still have dynojet springs in there

All good points, I'm really unsure about the conversion stuff at this point

I forgot to mention, the guy at dynojet also said that at WOT the slides are already fully up by around 4000rpm. That just doesn't seem right. I thought the slides weren't all the way up until 10-11k. Anyone know?

Edit: gonna go remove the glue right now and see what that does

I have a special container that I would use for the DynoJet stuff, if I had any...

icon_beerchug: I've just heard too many bad things about them when I was looking at kits for my bike. My po luckily just tuned it with stock stuff and spacers. Easy to correct.

LOL I feel the same way right now

I've heard bad things about them too. I would have never purchased a DJ kit or a 4-1 header. They just came with the bike. Stock needles, springs, and stock header are my next step.

Well, I removed the glue from the slides, it didn't affect anything as far as I could tell (went on a 30 or so min ride). I'm getting a stock header, stock springs, 138 mains, and stock needles (with one extra washer underneath).

Do you guys think the aftermarket midpipe I have will fit a stock header?

Not sure about the mid pipe, but that should be an easy fix.... Have you tried calling factory pro or someone else? Also jetsrus.com sells needles springs and the like... Just thinking may be more budget friendly then redoing everything.

Thanks man but I already have a bunch of the stuff. I figure that after I sell the 4-1 I shouldn't be too much in the hole. If my mid pipe is a different diameter, then how would I adapt it easily (I'm out at school without my highspeed cutter and welder)?

Just tried my new setup: stock header, same slip on, stock air filter, stock needles with 2 washers 140 mains, 40 pilots, and pilot screws turned out 2 1/8. When its real warm it has a 6.5-7k stumble, and a 7.5-11k stumble. From 11-redline it pulls moderately hard. When not as warm (like a quarter on the gauge), the 6.5-7k stumble is intensified and it will barely get past 7.5k at all. So both stumbles must be lean stumbles.

I'm starting to think this thing has a big bore kit or aftermarket cams or something. It would make sense, I got it from a real sketchy guy who I think might have stolen it (maybe from someone who installed those parts), but theres no way to tell because it has a legit title.

I guess next I'll try the 150 mains I have laying around. Can't hurt huh? What do you guys think?
