UPDATED WITH NEW INFO

Previous had it set up for cold weather from -5/25F to 10C/50F, now testing at +15C/59F to 20C/68F

YEAR: 2009 250R

INTAKE MODIFICATIONS: Kleen air delete. Uni filter Dual Foam 6 inch UP6200ST with PVC pipe as intake runner. The Pod filters are about 1 inch away from the battery box. I wanted to make sure the back of the pod filter airflow was not blocked by the battery box. The bracket back/under the gas tank with the four bolts, I had to grind down, because it had tabs for the old airbox, and was pinching my 6 inch pod filters

EXHAUST MODIFICATIONS: Stock

JET KIT: Dyno Jet

BRAND OF JET KIT: Dyno Jet Stage 3 #2393

MAIN JET:
DJ114/Keihin 120

PILOT JET: Stock #40

NEEDLE AND CLIP POSITION: 3 1/3 DJ needles with clips at the 3 position with 3 washers on top, and 1 washer under clip, which would make it needle position 3 1/3. Previously had it on 4th position but when it got warmer mid range bogged..

MIXTURE SCREW SETTINGS: 1.25 turns out.

ELEVATION: 75-646 feet.

Temperature: +15C/59F to 20C/68F

MISCELLANESOUS INFORMATION ABOUT YOUR BIKE’S JETTING SETUP:
Installed block off plate, Removed Air injection into exhaust to get rid of backfiring.

Had DJ112/Keihin 117 and Plugs were white at WOT. Switch to DJ114/Keihin 120 Main jet and #40 Pilot Jet. Bike pulls a tiny bit harder than previous. Might Try A DJ116/Keihin 122.5 to see what happens.
