Question about Yamaha YZ 450 F Motorcycles
Posted by Anonymous on
Sounds like the carb floats are sticking.
Allowing more fuel to enter the combustion chambers than can be burned off. Have the carbs checked/services asap.
The air/fuel ratio must be right for the engine to perform at peak performance. Hope you are changing that oil too!
