HOT CAMS Camshaft - Stage 2 for Yamaha YFM350 Raptor (Manufacturer's part number: 4115-2). Designed by HOT CAMS and tested on dynamometers with the support of competition teams, this Stage 2 camshaft is aimed at riders looking to take their quad's engine preparation beyond simple factory optimization.
The Stage 2 modifies the valve opening curve to promote a more dynamic power range, but it requires additional adaptations to fully express its potential: high-compression pistons and a large-diameter carburetor are recommended. This product is part of a serious performance-oriented engine preparation.
- Stage 1: increases torque and power without major modifications.
- Stage 2: intended for significant preparations, requires other compatible parts.
- Stage 3: developed for specific uses (e.g., supermoto) or increased displacement.
Two complete camshaft adjustment shim kits are provided to allow for precise timing adjustment. Installation is recommended exclusively by a professional with the necessary skills and tools to ensure reliability and safety. Compatible with YAMAHA YFM 350 RAPTOR 2WD (2011-2013).
