Thanks Jon
I am hoping the needles help the 2000-3000 RPM surge too. The bike is
a CA model with the "Special Needle". I backed the pilot jet screws
out 5+ turns and the idle kept going up. So far infact that one of the
screws fell out and I lost the spring while I was riding. The Screw
looks undamaged as it just sat between the starter and engine. I will
order a new screw along with the jets and needles.

Pilot adjustment should be set so that with the bike warm, there is no

The KLR needles are fine. Main jets only matter after 6000 rpm with

stock

airboxes the 122's will be spot on.....all you need to do is fiddle

with

needle height. Start with the needles at their lowest ( leanest) point.
They'll still be better than stock there but lifting them one notch

at a

time will get you to the right place. Look for improvements from

4000 to

6000 rpm...That's where the stock ones fall down once decent pipes are
fitted!

Good luck!

Hi Jon
I just got my bike, it was shipped from California to New Hampshire,
and so it took awhile. It is currently fitted with fish pipes but not
rejetted. I would like to have a go at it and would like some advice
on the best jets/needles. Based on your previous recommendations I
have located the KLX 300 needles and thought I would get a 122 and a
112 main jet in case I go back to the stock pipes. Would you recommend
going with the Kawasaki jet/needles or aftermarket like factory pro.
The Price is not much different when you start using combinations. The
bike still runs poorly during warm-up (30 minutes of riding) and I
have adjusted the pilot screw out to the point where the bike started
popping off throttle. I also checked the carburetors' synchronization
and it look good. I am hoping it is not the vacuum diaphragm. Anyway
thanks for your help.
Mike
