Being retired sometimes means I screw-around with my toys looking for stuff to do...and do stuff when its really not necessary. While I am waiting for some stuff to come in and have the interior out I decided it was a good time to check the valves on the front cylinder. Now at about 200 miles I set all the valves once mostly so I knew where they were. And now it have about 700 on it I wanted to re-check them cause...well something to do...and I don't plan on opening it back up for a while. I always set my valves mid-range unless I have a reason to do it differently and that's what I did last time. This time I found that over the last 500 miles the intake's lash depleted to the minimum clearance, which usually means seat wear thanks to the stock air filters, and the exhaust's lash had increased to the maximum clearance, which usually means cam, rocker or tappet wear and that could be just breaking in. After setting them back to mid-range the engine ran quieter and smoother. I still need to do the rear but will need to pull the storage box to open it up. I'll check them again in 5 or 6 hundred miles but I thought it interesting they had changed that much in such a short time. I know many people out there have never checked theirs but it might be a good idea to every once in a while.
