Adjusting the valves is cake. But u have to remove lots of shit to get to them such as the front fender hood and tank cover, gas tank and lights. then ur good to go.

Owners manual says like .0031in on intake and .007 on exhaust but go by what ur quad likes, if they still knock at those then tighten them some more.
