Hey All. So today, with the warmer weather on the horizon (hopefully), I decided to install my JetKit. I did not take any pictures during the install...as this has been documented quite heavily already by other members. I used gummybear's install log as my guide:

I just wanted to share my results with everyone.
BIKE: 2008 Ninja 250R (EX250J)
MODIFICATIONS: Two Brothers slip-on, K&N air filter, intake snorkel removed.
KIT: DynoJet #2193. Main jet used was DJ098. eClip in the third position from the top, with the two supplied washers on top of the eClip. Mixture screws are three full turns out, both sides equal. I did not deviate from DynoJet's instructions, I followed them exactly.
So after getting the bike put back together (as much as was needed to start it up)...she fired right up. No choke was neccessary, bike had not been started since yesterday. Idle seems to be a perfect 1300rpm, and at idle I could already tell the difference. The bike did sputter for about 10 seconds...normal while the gas flowed back thru the sytem. Revving at idle was smooth and fast. The bike no longer dipped RPMs to "think" about revving. I let it warm up for 5 minutes and then took a quick cruise around the block. All hesitation is gone. The bike is so much more consistent now, throttle-on-demand if you will. I am so pleased with the results.
Total install time, from removing the first screw on a fairing to starting the bike was about 5 hours. I wouldn't call myself a mechanic by any means, but I've tinkered with cars since I was 16. As this is my first bike...I'm still getting accustomed to it...learning what hose goes where, and for what purpose. If anything...the only thing difficult about this install was the space confinments. gummybear was not lying when he noted an hour to wiggle the carbs out. Now that I know what hoses go where, and what to pull off...on a second attempt I would say this could go much faster. It's all about learning.
