Valve tuning tips 2000 Qrunner 500

[CunningStunt]

I think i need to adj. the valves as I get some engine noise from the valve area when getting on the  throttle really good.  Lower rpm;s no noise.

 

Any tips/thoughts?  Also, i am relatively sure that the intake valves are the ones on the top and exh are the ones on the exhaust side...just need a dummy check as I have never worked on an engine before.

Intake are on top 

Exhaust on bottom

Intake: .05-.10mm (.002-.004 inch) Exhaust: .17-.22mm (.007-.009 inch).

So, I went in, rotated crank to the alignment mark for TDC - valves appeared shut, and the rockers moved a freely on intake and exhause side of valve port.

I do not have the adapter for my compression tester to fit the small plug threads but I figured since piston was at top, mark lined up, and the rockers had some play that I was TDC on compression stroke.

 

Am I thinking this through correctly?  I have never done valve adj. before and when I was done, I started her up and still hear noise when getting the RPM's up there and it sure sounds like the valves or something in the top end.

 

I also don't want to rule out that possibly the previous owners could have adjusted the valves on the wrong stroke and gave therefore masking the fact that it may not have actually be on the compression stroke that the rockers had play for me.
