Hey, my YZ85 is acting like it's not getting enough fuel. Cleaned the carb cleaned the fuel filter cleaned the air filter checked the reeds, just don't know what to do. 2003 YZ85

Did you change the plug a lot assume it's okay because bike is running not the case with 2ts.

could be a cheap fix.

Check compression, could be time for a top end. If it was on its way out already, might have finished it off leaning it out as you ran out of fuel. How many hours on the current piston?

 

If it is fouling the plug, chances are its getting plenty of fuel, just not burning it.
