I've got an 04 300 EXC that has just recently started to give me some grief when it stalls out on me pretty frequently now. I'm pretty certain that it is jetted very well including the slow/pilot/idle circuits as I've not had this issue before and it runs flawlessly other than this issue. The problem seems to be that it will not idle in gear with the clutch lever pulled in. I did not realize this at first and simply increased the overall idle speed. But... It idles very high (now) in neutral but once the bike is in gear (1st or 2nd typically) it will most likely die (i.e. clutching in slow tight downhill sections, etc). Has anyone run across something like this before? I'm now thinking it's more a clutch issue. Or tranny? Since it idles fine in neutral (when set properly) but it just will not idle in gear. And the clutch does seem to "grab" a little when I try to start it in gear as well as being more difficult to start in gear sometimes. Would this be cause by a worn out clutch/plates? Or maybe the hydro system? Or old fluid needing changed? I'm just not sure what would cause something like this. Any help or suggestions would be greatly appreciated! Thanks!
