Making A Can Am DS90X Fast(er) Part 2

In Part 2, we port the cylinder head, set cam timing, install the clutch springs from the Hetrick Racing Kit, Install the new intake and carburetor from the kit, install the new exhaust from the kit, and install the new rear sprocket and chain from the kit. I wasn't able to figure out how the chain tensioner would work on this quad. It's a great upgrade, but I wish there was an aftermarket CDI box available to take more advantage of these upgrades. I still need to do a little fine tuning on the new carburetor. I'm waiting for some pilot jets to arrive. Hopefully we are able to get it all dialed in before race season.
