Does the motorcycle secondary air valve need cleaning?

[OEvangeline]

Motorcycle secondary air valves generally do not require cleaning. During use, they rarely encounter issues. As long as there is no air leakage, including the valve body and its connected rubber hoses showing no signs of aging, cracks, or air leaks, it should function properly. Principle of secondary air intake: Secondary air intake utilizes the vacuum pressure difference in the intake manifold. By connecting an adjustable air intake device externally to the engine's PCV valve (Positive Crankcase Ventilation) pipeline, an appropriate amount of fresh air is introduced to improve volumetric efficiency. Key points for using secondary air intake devices: The most crucial aspect of a secondary air intake device is maintaining an appropriate air intake volume. The key to quick performance lies in controlling the amount of air introduced. If the air intake is too low, the effect will be poor; if too high, it will reduce vacuum pressure, affecting the assistance of the brake vacuum power booster and making the braking force required heavier.
