I posted this information before based on my learning curve. (slow) Seams like it has already been answered but here are my 2 cents with a little more detail that I found to be useful...
Valve lash - It came from China with “0” clearance. There is extensive information on this topic but I needed further description on “Top Dead Center, Compression stroke” (yeah I am a newbie motorcycle mechanic.) With the valve cover off, rotate the motor counter clockwise until you see the Intake valve close. Slowly keep turning until you first see a double line then a line with an “F” and then finally come to rest on the line with the “T”. I found it tough to tighten the nut down and stopping the adjustment screw from turning as well. I found that if I tightened the nut down on a .005 feeler gauge it would create a snug .003 on the intake valve and a .006 on the Exhaust valve it would create a .004.(Some clicking is expected.) How much clicking? Mine has a slight click sound and my hawk runs awesome.
