125-200cc Carb Needle for WR150

I have a 09 WR 125 with the factory 144 kit. Also I have a 38mm PWK Airstriker on it. I have the JD needles that came with it but am wondering what needles other have good luck with
The last few rides have been very similar in temperature. Here is what has happened.

I had JD Red #4 and it felt rich at ¼ throttle.
Went to JD Red #3 and ¼ was good but it was weak off idle up to about 1/8.
Went to JD Blue #3 and it felt good.

Next ride the bike was weak off idle again. Turned in the air screw a full turn and the problem disappeared.

The bike runs decent now but still makes a lot of spooge in the first quarter of the throttle but I don’t think I can lean the needle without messing it up off idle. I guess I could try a bigger pilot but I think it is about right. What other needles are people using?

CEL is working great for me so far. I took the opportunity to learn more about needles and am still playing.

Have you discussed problem with James Dean ? (not the one that died in 1955)

Geno said - " 48-dcf is what works for me" - Keihin needle
this is a richer needle apparently -
I believe blue needle was richer yet worked well even on a hot day what size is the blue needle? Until my next ride I am happy with blue needle

your not alone ! I have the same bike with the pwk(non airstriker) jd red#3 180 & 52p and air screw 1/4 out this has been my best set up yet! still have spoog but no off idle bog

Spooge means combustion temps are too low, from being fuel rich, it is usually unburnt fuel. It could also mean you need new packing.

Later,

I tried a DCL in the third clip today and it ran real well. I will have to see if it is still good from ride to ride.

whats a DCL needle?
do the mikuni needles work/fit in PWK s - gues not or someone would have tried

You will always have some spooge with a Spark arrestor....it is just what they do.
