Did something happen recently to change the jetting specs ?
- new gas type ?
- colder weather ?
- could be you have some blockage in one of your air jets...did you recently run in some high dusty environment ?
Anyway, take the carb apart, clean all and blow compressed air throught all the jets (be carefull of the washer & spring in the fuel screw recess...make sure you have them in your hand before blowing air into anything !
- bk mod malfunctioning ... ??

another question...last spring i was doing some woods riding and got a branch wedged agaist my engine...when i pulled it away, the wire that goes in to the spark plug cap came out...i just pushed it back in... since then i have done dozens of rides. Could that be a contributer to my problem? maybe the connection is corroded or arcing...causing a misfire prob...in-turn fouling the plug...

Did MD recently start mandating oxy fuel in your area for
this time of year?
I have had more trouble than you'd believe running oxy fuel
in my '01 YZ426. I switch to race gas in the winter and the
problem goes away.
