Running lean

Forums

Bikes been running well, left it for a month with the battery on charge, upon starting the engine is running hot and lean (popping and plugs white) 

Plenty of fuel getting through and no apparent air leaks, I will strip carbs down and check blow through and clean.

Bike is fitted with electronic ignition 

Any thoughts please?

Drill out the pilot jets with #78 or 16 thou drill, the jet is so small carb cleaner and air will not dislodge the crud, also check the pilot fuel passage and the 2 small holes on the engine side of the spray tube on the floor of the carb venturi are open.
