Yamaha YFM 660 Raptor 2 WD [2001-2005] - Camshaft - Stage 2 Yamaha YFM660R

HOT CAMS Stage 2 camshaft for the Yamaha YFM 660 Raptor

This Stage 2 camshaft from HOT CAMS is intended for further modified engine structures. It was developed on test benches and tested by leading teams. Within the three-stage HOT CAMS program, Stage 2 is aimed at applications where additional changes to the engine are planned.

Function and coordination

In order for the Stage 2 version to achieve its intended potential, further adjustments are required. For example, HOT CAMS mentions hi-compression pistons and a larger carburettor. The camshaft should therefore be selected as part of an appropriately coordinated engine structure.

• Stage 2 version for further modified engines
• Developed on test benches
• Tested by leading teams
• Two sets of valve shims included for proper adjustment

Vehicle assignment

The camshaft is the Yamaha YFM 660 Raptor 2WD with the complete year range 2001-2005 assigned. This clear assignment supports the targeted selection of the corresponding vehicle.

Factual information on assembly

The installation and the necessary coordination should be carried out by qualified specialists using suitable tools. This is particularly relevant because the Stage 2 camshaft is used together with other engine adaptations and the included valve adjusting washers must be adjusted appropriately.
