Hey everyone, I'm working on a 2006 WR450F. The bike will run all day with the choke on but the second you push it in, the bike automatically dies. The bike was sitting for a while so I tore down the carb and cleaned it out. No change. So I pulled it down a second time, this time more thoroughly, and still no change. The bike is completely stock with the exception of a cut grey wire and the baffle removed. Jetting is completely stock: 165 main, 45 pilot, 50 leak, and the needle only has one position. I fiddled with the fuel screw and at three turns out, it would idle for about two seconds before it would die. I am completely stumped and starting to think that it's a jetting issue. Can anyone give me any advice. I want to make sure it is a possibility of lean jetting before I drop $80 on a JD jetting kit. Thanks for any info!
