How hard is it to install a Mudbuster cam in a 2006 Yamaha Grizzly 660 and are there any special tools needed to install it. I am a mechanic by trade and have tools. Also what exhaust would work good with this cam? Do you need the Raptor center valve springs?

 

I installed a cam on my friends raptor. If your a mechanic and understand how it all works you shouldnt have any trouble. One thing you need to make sure of is the decompression mechanism is in the right way.
