HOT CAMS Stage 2 intake camshaft for the Yamaha WR 250 F

This HOT CAMS intake camshaft is a stage 2 version for the Yamaha WR 250 F (CG 16) built between 2003 and 2004. It is aimed at engine structures where, in addition to the camshaft, other coordinated changes are planned. The camshaft was developed on test benches and tested by leading teams.

Execution and function

• Component: Camshaft for the intake side
• Version: Stage 2
• Brand: HOT CAMS
• Areas of application: engine, valve control and camshaft

The Stage 2 version clearly differs in its requirements from a Stage 1 camshaft. In order for it to achieve its intended potential, further engine adjustments are required. High-compression pistons and a larger carburettor are mentioned as suitable measures. This makes the product suitable for specifically planned conversions and not as an isolated change without taking the rest of the engine setup into account.

Vehicle assignment

• Yamaha WR 250 F (CG 16)
• Full year range: 2003 to 2004

Model code and year of manufacture should be compared to the vehicle before selection. The clear assignment helps to select the intake camshaft for the intended motorcycle.

Notes on assembly and coordination

The installation and the necessary accompanying engine adjustments should be carried out by qualified specialists and with suitable tools. Proper planning is particularly important as the Stage 2 camshaft requires further modifications to the engine in order to utilize its potential.
