Hi. I have a strange problem with my 04 wr450. I have read the sticky thread and tried to follow it to adjust my fuel screw. The problem is that I need to turn the fuel screw about 3 turns out to get some kind of idle, without having to adjust the idle screw way in. I have tried several pilot jet's (48 std, 50, 52, 55), but strangely enough the behavior doesn't really change. I have tried cleaning the carb several times. I have checked every jet, and the only thing that is not standard is the main jet (a little bigger then standard) och the needle (raised one step). Those changes shouldn't have anything to do with my problem right? I have checked the float level, and I think it is correctly setup. Tps has been adjusted, but it doesn't mater if it is connected or not. I have replaced the cold starter (starter plunge) and the seal on the warm start. I have tried both the original fuel screw and an aftermarket screw (the o-ring, washer and spring are all there in the correct order). I have looked for leaks around the carb with start gas. Pulling the cold start raises the idle rpm. So does pulling the hot start when the cold start is pulled (doesn't really change the ilde rpm much when the cold starter is not pulled, but it still helps sometimes when I'm starting it warm). Does anybody have any idea what I might have overlooked? Other then this, the bike is running fine with very little bogging. Some loud bangs when coasting and lots of smaller bangs if I turn the fuel screw in and compensate with the ilde screw. I hope that by correcting this problem, I might get it a little bit smoother transition from idle to small throttle openings. It currently feels quite nervous.
