I've been a lurker for a long time but this is my first time posting as I cannot find and answer to my problem. I have a 2007 drz400sm with a stock exhaust and yesterday I attempted to do the 3x3 mod and rejet the carb. I used the JD kit as I had heard it was the most complete. The I installed it as per the instructions on the first page of the master 3x3 thread: - 150 main jet - 25 pilot jet - 2nd clip on (blue) needle from top - 2.5 turns out on fuel screw After I was finished and got the bike back together I can't start it without pulling the choke all of the way out and once I push it back in the bike dies. Could I have made an error while installing something in the carb? Does the description of my problem help narrow anything down? I'm in Kelowna, BC which is 344m in elevation and the temperature has been around 60-65 degrees f.
