I HAVE A 05 GRIZZ 660. I HAVE A BIGGUN SLIPON AND K/N FILTER. I HAVE ALL THE BOTTOM END IN THE WORLD WITH STOCK TIRES. BUT IM LOOKING TO GAIN SOME MID AND TOP END FOR THE LONG STRAITAWAYS. IM THINKING OF TRYING A HOTCAMS STAGE 1 RAPTOR CAM. I WAS WONDERING IF THEIR IS ANYONE OUT THERE THAT HAS TRIED CAMMING A GRIZZ AND WHAT WAS THEIR RESULT. I PLAN ON USING THE STOCK SIZE TIRES.

 

is their anyone out their that has expeiremented with cam shafts in a grizz 660 at all. please help

 

The stock Raptor camshaft is a little more aggresive than the Grizz. A stage one should work fine for you.Any bigger than that I dont think the stock intake and carb will keep up. Just remeber that clutching is every thing with auto quads. Check out Highlifter.com. These guys are experts with utlity machines.
