I previously posted my plugs were black and the low end was hard to control.

There were errors in my post, my mechanic friend looked at the plugs and there were ok, I was not looking at them right. My low end was way too touchy. I just crack the throttle just a hair and I could cruise around the city, but if I moved it back a hair, I would lose power. Very hard to control. Middle range and Top end pull hard and was EXCITING!!!!

I moved the clip to the 2nd spot from the top, below is my current results and other notes.

YEAR: 2009 250R

INTAKE MODIFICATIONS: K&N KA-2508 Similar to stock, De-Snorkeled

EXHAUST MODIFICATIONS: Stock

JET KIT OR STOCK? Jet Kit

BRAND OF JET KIT? DynoJet

MAIN JET: DJ 98

Pilot Jet: Stock

NEEDLE AND CLIP POSITION: clip set 2nd from top with 2 washers on top

MIXTURE SCREW SETTINGS: Tried 2.5 to 3.0

ELEVATION: Toronto, Ontario 246FT 75 Metres to 686 FT 209 Metres

MISCELLANEOUS INFORMATION ABOUT YOUR BIKE’S JETTING SETUP:

Currently using 2nd clip from top.

Top End: Pull better than stock not as good when the clip was on the 3rd position.

Middle Range:
Pull better than stock not as good when the clip was on the 3rd position.
Stumbles at 9000 RPM, I did not have this problem when it was on the 3rd position.

Low End:
Easier to control, better than stock, easy to ride in town, not as fun as before when I had it in the 3rd position.

Misc Notes:
I no longer have the strong smell of gas from the exhaust when it idles, or people smell gas behind me. My idle drifts from 1000-1200 no matter what I do, I had this idle drift before I re-jetted. I'm going to clean my carb, and try choneofakind advice. I am not going to place the clip in the third position like before, I going to add washer to try to make in 2 1/2 position. I will let you guys know if it helps.

Cheers!!!
