I think I remember the valves getting louder before I parked it. Both were loose so I adjusted them down to .08mm intake, .13mm exhaust since that is what I had feelers for and read that is close to what is recommended.
I'd complain about adjusting valves, but it is a walk in the park compared to multi-cyl and especially shim n bucket. The exhaust was only marginally more annoying next to the frame tube. Gosh don't even need to remove and reseal a big valve cover. I feel spoiled!
