ATV Valves & Valvetrain Parts

The valves and valvetrain mechanism as a whole are responsible for the main engine characteristics, and even minor malfunctions can seriously affect performance. Meanwhile, the valvetrain gradually wears out, and after certain mileage, it needs repair. Some of the most common signs of it needing attention include clicking noises, similar to the sound of a sewing machine. The valves can get coated in varnish and carbon formed from the burnt motor oil. Lots of bluish smoke coming from the tailpipe is another sign of problems with valves or seals, although they can also be caused by the worn-out piston rings.

If the guides and seals are nearing the end of their service life, then you’ll have plenty of motor oil seeping through and combusting in the cylinders. Besides, another tell-tale sign is considerable power loss throughout the whole RPM range, with the motor giving out down to two-thirds of its output. For you to avoid any and all of the aforementioned issues, you need to maintain your all-terrain vehicle’s engine with quality parts.
