MOOSE offers a spring-loaded exhaust valve kit designed to ensure reliable, long-lasting refurbishment of the timing system, replacing wear-prone original components on 4-stroke engines. The kit typically includes high-strength stainless steel exhaust valves and reinforced springs, providing significantly longer service life than original titanium valves. Black Diamond-type valves are designed to offer greater resistance to high temperatures and wear, while improving engine performance and gas flow.
