Thinking more about the valve adjustment being tight. As the head of the valve closes by spring pressure, it wears the valve seat and valve face, raising the valve stem as it pulls into the cylinder head. This reduces the valve clearance over time and will begin to prevent the valve closing fully and therefore effecting the cylinders compression. Wear of the Cam and Rocker surfaces would tend to loosen the valve clearances but this must be insignificant compared to the valve face and seat wear.

Yep. Seen it happen many times.

You are correct and this causes a lean mixture and acts as a vacuum leak. When this occurs you will notice the header pipe glow from the lean hotter mixture

Great explanation of the work john. Just a few comments that are not that important. 1. Did you think of doing a compression test. 2. I use .05 and 0.1mm feeler gauges and bend the ends (I like tool mods). 3. The tappets should wear loose so agree someone has tightened them up. My gs850 has shims and they wear tight as the valve faces wear more that the shim cam interaction. 4. I would counter sink the battery screws , as just temporary ok. 5. those farm bikes normally have battery earth problems as the cow manure corrodes earth frame connections. Good video liked the valve adjustment using the pitch method.

1. I don't have a compression tester. Yes that would have confirmed my suspicion. Others have reported tightened valves. How it happens is a mystery to me. 2. I don't have 2 or 4 thou feeler guages. I should get a set that does. It is difficult to get the feeler under the tappet and get an accurate reading.
