Camshafts and Valves for Scooters

The camshaft and valves are located in the cylinder head of 4-stroke engines. They are part of the valve timing system / valvetrain and are essential to its operation.

This category includes all spare parts related to the valve timing system: camshafts, valves, shims, springs, timing chains, valve stem seals, rocker arms, and much more.

Parts are available for the most common models: Peugeot Kisbee and Django, Chinese GY6 scooters, Yamaha Aerox 4T, as well as Piaggio Zip 4T.

To offer high-quality components, we work with well-known brands such as Naraku or directly with manufacturers like Yamaha, Piaggio, and Peugeot.

Tuning and Maintenance of Valves and Camshaft

4-Stroke Engine Tuning

Performance camshafts are the most effective way to increase the performance of a 4-stroke engine. Modified valve timings allow for significantly higher engine speeds, more power, and higher torque. You can also install larger valves, although this requires machining the cylinder head or using a special cylinder head.

CAUTION: When tuning a 4-stroke engine, carburetor tuning with jets or fuel injection tuning with an ECU must be adjusted, just as on a 2-stroke engine.

Valve Maintenance

Like many other components, valves are wear parts. As wear increases, valve clearance decreases, leading to power loss and starting problems, especially when the engine is warm.
The shims can be replaced to correct the valve clearance. However, the valves will eventually also need to be replaced.

CAUTION: Replacing these parts requires extensive mechanical knowledge.

How to protect Valves and Camshaft

The following rules generally help protect the valves:

  • Allow the engine to warm up properly
  • Do not run the engine into the rev limiter
  • Clean the air filter regularly
  • Follow the specified service intervals (oil change and replacement of the filter)
