HOT CAMS Stage 2 intake camshaft for Yamaha WR 250 F

This intake camshaft from HOT CAMS is intended as a Stage 2 version for targeted engine conversions. The manufacturer's camshafts were developed on test benches and tested by leading teams. Within the three-stage product range, Stage 2 is aimed at more extensive engines.

Function and coordination

In order for the Stage 2 camshaft to achieve its intended potential, further changes to the engine are required. HOT CAMS specifically mentions a high-compression piston and a larger carburettor. The selection is therefore suitable for a coordinated tuning concept and not as an isolated individual measure.

• Inlet camshaft in Stage 2 design
• Designed for further modified engines
• Developed on test benches and tested in use by leading teams
• Two sets of valve shims included for proper adjustment
