Again, thank you for the help
Lately I have started to refine the 250 jetting a little more,and have been using a triple taper Kawasaki/Suzuki needle with a little leaner 1st taper than the Suzuki NExx series needles, and really like it. The setup is N3WK needle #4 ,http://www.partzilla.com/parts/detail/suzuki/SP-13383-37EQ0.html a 40 pilot and 175 main
I have been taking the useless stock jets (155, 158 mains) and custom bores on the lathe :D
The N3WK is another triple taper Kawasaki/Suzuki needle that is similar in profile to Suzuki's NExx series. IMO, bike seems to run even cleaner off the bottom than the NECJ and then revs quicker, but smoothly throught the middle and into the same topend as the NECJ. It's a nice clean setup for guys that are using the stock slide. As an added bonus for 90% of those that are using the NExx needles already, I find that it is a direct replacement for that needle meaning, I leave the pilot and main the same as the NExx needle and just replace the needle and go.
You can buy the N3WK needle through either Kawasaki (99' kx250) or Suzuki(00' rm250) , but the needle is cheaper when bought through Suzuki for some reason.

250's= N3WK #4, 40 pilot, 175 main, and startout at 1.5 out on the air screw.
300's=N3YK #3, 40 pilot, 175 main, and air screw @ 1.5.
These are safe starting #'s for the sx. I have run the 250/300's xc and xc-w's with a 38/40 pilots and 168 mains safely.
Also the 15's pipes still crac. Mine lasted 5 hours.
Pit Row
For those interested, the suspension on this bike is flat out awesome, no I am not crazy, nor are the guys ( who have spent big bucks on their bikes suspension) after they ride this one. What I discovered was that it takes a good hour of initial riding with the clickers set very soft to break in and then adjust the clickers to balance. I have 6 hours now and the settings couldn't be better for where I ride. 25mm static sag, 1 3/4 turns out on high speed comp, 12 clicks out low speed comp and 10 out on the rebound. front, 12 comp, 10 rebound. I am using stock springs, and I weigh a fluctuating 175-185 throughout the year. I also run the bars in #3 forward position.
I am just chomping on the bit to get out in morning. Thanks for all who contribute.
Cheers
