Usually, the motorcycle should be cleaned and maintained once every 30,000 kilometers to 60,000 kilometers. However, the cleaning and maintenance of the throttle valve is not the more frequent the better. Excessive cleaning and maintenance of the throttle assembly will damage the special coating of the throttle chamber. If the maintenance details are not paid attention to during cleaning, the coating will be damaged and cleaned away, and the inner chamber will lose the coating, which will cause greasy adhesion, accelerate the aging of the throttle valve or cause poor engine idle failure.
