JUST BOUGHT BIKE , 5300 ORIGINAL MILES, SHOWROOM APPEARANCE. I NOTICED SLIGHT, WHITISH BLUE SMOMKE COMING FROM RIGHT SIDE EXHAUST. I REMOVED FIRST CYLINDER SPARK PLUG RIGHT SIDE AND WAS BLACK AND A LITTLE WET WITH WHAT APPEARED TO BE GAS. ALSO NOTICED OILY SUBSTANCE DRIPPING FROM CARB INTAKE AT AIR FILTER. MY QUESTION IS WILL DIRTY CARBS(SITTING TO LONG WITH GAS IN CARBS) MAKE THIS HAPPEN?
