Hey Raptor 660 riders! Ready to wake up that engine and get some serious performance gains? This Hot Cams 4050-3 camshaft is a Stage 3 grind specifically designed for the Yamaha YFM660 Raptor models from 2001 through 2005. Important note: this cam is NOT for stock engines. It's meant to be paired with a big bore or stroker kit (like the Hot Rods kit) to really unlock its potential. It's a single-cam design that uses the stock auto-decompression mechanism, so that's one less thing to worry about. To run this cam properly, you'll also need to grab the Hot Cams valve spring kit (part # SKYFM660S2) – don't skip this, it's required for the higher lift and RPM. If you're building a high-performance Raptor for racing, dune riding, or just want max power, this cam is a top-tier choice from a trusted brand in the ATV performance world. Double-check your model year and get ready for a whole new level of throttle response!
