ATVs have changed the approach to off-roading by broadening the range of possibilities for many adventure seekers. As in every other vehicle, the engine is the very core of your four-wheeler, and its top shape is essential to ensuring a safe and exciting riding experience. Most ATVs are equipped with two-stroke motors, which are less refined but more effective than four-stroke engines. Within two-stroke engines, the delivery of the air-fuel mixture to the crankcase is controlled by reed valves.
The operation of a two-stroke engine involves the differential of pressure and the cyclical opening of the intake and exhaust valves to perform its cycle. A reed valve allows the blend of air and fuel to flow in just one direction – from the carburetor into the crankcase. Over time, its petals can get cracked, chipped, and may not close tightly against the block. This results in poor engine performance and can cause rough idle, reduced power, and other issues. We have a large selection of ATV reed valve systems and related components such as gaskets, replacement reeds, clamps, and spacers. Their quality, durability, and performance are ensured by reputable aftermarket brands such as Boyesen, Pro Design, and Moto Tassinari.
