Did some searching no luck. Have a 97 xr600, got it used a few months ago. Hard to start but a quick shot of starting fluid and it fires. Problem I am having is it will hiccup and die at idle. If I blip the throttle or rev it a bit it will stay running, let it down to idle and it will die after about 3-10 seconds. Happens when choke it off. Also it will slightly backfire one or two times on decel. Lean pilot? PO cleaned the carb I was told so I GUESS it is not a dirty pilot (to cold to pull it apart right now) Air screw? How many turns out stock (no manual to check)? What is everyone running for a pilot? I did take her for a quick hoot of a ride in 8" of snow yesterday. Runs great other than idle, cough, hiccup, decel pop what ever the "proper" name is for the condition.
