Hi

I have just installed the #112 jets, N96J needles and larger snorkel. I have put back the original air filter as I wanted to keep everything within the original spec.

I took the bike for a short spin around the block and there definately is a great inprovement in the performance. It pulls stronger and revs quicker. It probably is not so fuel/air starved anymore. I set the air screw at 1 3/4 turns out. The spec says 1 1/2. The N96J needles are a lot thinner.

I will take the bike on a longer run this Sunday and see how it goes. From what I have felt on the bike so far this easy mod is highly reccomended if you have a newer "greener" KLE 500 and want to squeeze out a few extra ponies without too much fiddling and fuss. I am a bit two minded about re-installing the DNA air filter as I am not sure how this affect the air/fuel ratio's and the performance. I gave the bike a good caning (WOT) and there was not any stumbling or hesitation.

To sum up the parts to change are as follows: (Kawasaki OEM part no's)

14073-1481 Duct, Intake (larger air box air intake snorkel)
16009-1657 Needle-Jet N96J
92063-1117 Jet, Main #112 (main jet)

I will report back on my Sunday ride.

Forgot to mention. I got the main jets from another dealer. The main jet is not a genuine Kawasaki part. It is inscripted " 112 Factory K " I was wondering if the size shown on this jet (#112) is the same size as the genuine 112 jet. It physically looks exactly the same exept for the inscription. Any thoughts?
