I have an 2007 Arctic Cat 400 auto 4x4 with 4 valves. i would like to adjust the valve clearance and to do so i obviously have to know which valves are intake and which are exhaust, i rather not take the head apart to figure out which is which, i know somebody out there has some expertise and your wisdom would be greatly appreciated, thanks!

 

The 2 exhaust valves are forward, toward the exhaust pipe, and the 2 intake
valves are rearward, toward the carb. You will need small, flexible feeler guages
to get in there.
