Lousy speaker on my tablet so hard to tell. You say valves are adjusted but are you sure it was done right?

It sounds normal to me. All I heard is the normal taping of the valves.

Yes they will be a little noisy. What do you have them set at. I have mine set at .002" intake and .003" exhaust.

You will be good at that. When you stop hearing the tapping you will know it's time to adjust valves.

Have you checked all of your motor mounts? They aren't super tight, about 18-22 lbs respectively. Maybe you have something buzzing/tapping to the vibration of the motor?

I'm with Bruce; sounds like the starter clutch is making noise.
