Camshaft and valves

The camshaft and camshaft valves are part of a 4-stroke engine. The camshaft controls the opening and closing of the valves by converting the rotary motion from the engine into a longitudinal motion. The valve is responsible for letting in fresh gas and getting rid of burnt gases.

Generally, the intake valve separates the intake from the combustion chamber and the exhaust valve separates the combustion chamber from the exhaust. We carry camshafts and valves as well as accessories such as timing chains, bearings for 50cc scooters with 4-stroke engines and maxiscooters. Manufacturers like Naraku specialize in the 4-stroke market and offer a wide range of replacement camshafts.

Manufacturers like Malossi also offer tuning / sport camshafts with modified angles to optimize engine performance. The valve systems can be optimized as well, for example, with reinforced springs and valves with improved sealing properties and longer life.
