God, those wheels look sexy. I like the black, But I know it'll just be a matter of time before they are black with little streaks of silver showing thru..

There was something about starting this thread that just changed my life, I cant seem to get a moment to make it over to the shop. I want to start wrenching already!

Hopefully Saturday evening I can get started, but only time will tell.

Yeah, we got powers.. You get sum too when you join up.. The black Excel rims on one of my Husabergs doesn't show silver - Well, I say that but could that be right ? (It's out at the Ranch 50mi away..)

Its a big old YET, just wait until you're spooning a tire after riding in rocky, and muddy conditions!

Things I learned from that occasion..
-Don't forget the factory tool kit..Duhhh (luckily some others guys were out riding to, why I have no idea.. the rain was literally coming down sideways.)
-Bring a couple extra shop rags
-WD-40 works wonders when re-seating a D606

I haven't been wrenching lately. Finally found some time this weekend!

So, the last time I tore into the bike I was having starting issues.... I have now sorted that out, in the process I took the time to check & adjust the valves, and put in a manual CCT.

The starting issue turned out to be a bad starter Idler gear..I bought a 2010 KLX two weeks ago, so I was able to pull that part out of that bike, and put it in this one (for quantification purposes).

Now I'm trying t sort out its carb issues.

It starts, and idles great (after drilling out to .018").

My shop is at 250' above sea level. Ive got a 128 main, 35 Pilot, Needle is set at 3rd clip from top. Running FMF Q4, and the FMF mega bomb. No cover on the air filter.

I had a 40 pilot in it, but when I went up in the hills, around 1,000ft it wouldn't idle / start for crap. So I went back to the 35.

Which brings me to my next question.. After switching back to 35 (which is what it came with) I went and test road it. It seems like it would surge past 3/4. So I drop the clip on the needle, this made the bike pull really hard down low, and it would run in the upper rpms without surging, but would completely cut out after letting off the gas.

Which place are most of you guys setting yours, I know its different for everyone based on sea level.

Your exhaust system + lidless airbox can make huge power but no one has data to verify proper fueling with your components.

I do know exactly how to properly fuel your bike with DynoJet components.

The #40 pilot jet needs to be put back in and the fuel screw set to half way between idle drops, at your altitudes.

Pilot jets have nothing to do with fueling at 3/4 throttle. You may have something going wrong internally - what is the float level set to ?

I'll check on the float level tonight.

When I got the bike the lid was off, and the jetting was the same as it is now. 128 main, 35 pilot.

And it ran great at sea level, and up in the mountains. I've had the bike above 5,000ft alot.I only need to ride a few hours to be up that high, so I'm thinking its still a needle setting.

I was reading one of your post (Klxster), and you said not to drill the slide hole out to 7/64ths. Could this be causing the midrange power issues that I'm having? What's the stock slide hole size?

I'm trying to adjust the are between 1/4 & 3/4 throttle.

I've got an after market needle, with two washers. I'm not sure which needle it is exactly. It had two washers on it... I should have been taking a little bit more time to see what the exact placement of these washer was, and then recorded it.. but I didn't.

After reading the dinojet sight, per there instructions it sounds like the washer go on-top of the need clip, for storage. Unless you need to make fine increment adjustments, then they will go below. Essentially making half clip positions. Please feel free to correct me if I'm wrong.

You are correct about the washers. The only rule is that both must be used at all times. The normal usage is to put both above the clip. "Advanced" tuners can vary the washer placement - I'll turn you into an "advanced" CVK needle tuner : Once the proper main jet is determined - providing proper AFR at WOT between 8k and redline, the needle and its' clip will control fueling from around 3.5k to about 7.5k at WOT... With any given needle, the top notch will produce the least amount of fueling in that range, and the bottom notch will produce the most fueling in that range.. Each notch will enrich or enlean(lol) that range of RPM @WOT ABOUT 1 point of AFR. So, while normal usage is to put the washers on top of the clip, if you put one above and one below, you are using a half notch setup on the needle.. For instance, clip on 3N(3rd notch down from the top) w Washer below and above = 3.5N , both washers below = 4N.. You tune for best WOT operation and then ride it to test all-around performance..

An interesting sidebar is that for those running a full performance exhaust with the airbox lid off (as it should be) , the stock needle with 2 DJ washers below its' retainer + a DJ144 main jet with a drilled slide or a DJ slide spring will fuel the bike "well".. at or near sea level..

If you have a drilled slide, you certainly could have abberant slide behavior IF you are also running the lighter DJ spring or a shortened/weakened stock spring.. You see, the spring and needle have to be matched up properly as they work as a team..
