That's a good point -- lots to be said for simplicity.

On a related topic, I notice that the service manual calls for a valve lapping every 1,000 hours. That sounds excessive to me, but as I've said, I want to keep it running for a good long time, and skipping maintenance doesn't seem like the way to do so.

I don't have the necessary tools or expertise to service the valves, so when I do it, I'd probably just pull the head and take it to a machine shop for the service (good opportunity to perform other work on and around the head).

It sounds like you take good care of your motor -- when and how do you handle the valve lapping requirement?
