Thanks for the relies!!!
I found this:
KLX Needle Kit
For 1987-2008 KLR650
The small brass collar/spacer goes above the circlip. Do not install it below the circlip. It will make the bike too rich.
Needle clip position numbers are counting from the top down. The top or #1 position, is full lean. The lowest position, or #5, is full rich.
Be very careful not to damage the carb slide diaphragm. Inspect it carefully. Replace it if you find any tears or pin holes. A replacement is available through Harley Dealers for much less than the Kawasaki part.
When reassembling the white plastic needle retainer, make certain it is not obstructing the slide lift hole. When seated correctly, there wil be very little vertical play in the needle.
The KLX Needle is much richer than the stock needle. If nothing else is changed, it requires a smaller main jet, and leaner mixture settings that a stock needle. It is also slightly richer than the Dyna Jet Kit.
A good Baseline setting for a total stock KLR.
o #140 Main Jet
o #2 Clip Position
o 1 Ύ Turn Mixture Screw
Removing the airbox snorkel may require a #142.5 main jet, and/or using the #3 clip position.
A less restrictive exhaust system, and/or air box mods, may need a main jet in the #142.5 to 150 range. The stock main jet (#148 for 87 to 07, #145 for the 08) often works well. It may also need the needle circlip in the #3 or 4 position.
Exclusive use at higher elevations, over 5000 foot, may need a main jet of 1 to 2 sizes smaller. A stock bike may need a #135 or 137.5. Removing the snorkel is highly recommended for all KLRs, but more so when used at altitude.
It is not required to re-jet for occasional use at altitude.
Mixture screw settings will vary greatly from bike to bike. The effective range of the mixture screw is 1 to 3 turns. The greater the number turns, the richer the low speed mixture.
The mixture screw and needle position overlap to a far greater extent than most people realize. (As does the pilot jet.) In general, the richer the needle is set, the leaner the mixture screw should be set.
A small #4 washer can be used under the needle circlip for fine needle adjustments. A .020 thick washer will give you a 1/2 clip richer change.
Opinions will vary but you might start with this, given that your exhaust is a bit freer flowing and the snorkel is out:
I'm going to try it out with a KLX needle that I already have. Seems to be the way to go after reading many and finding a common theme.
