Looking at the service schedule on the Pioneer 700 I see it calls for initial service at 100 miles/20 hours. Then looks like every 600 miles. Each service includes oil change and checking valve clearance. I plan on taking it to the dealer for the initial service because there are a few things that need to be adjusted under warranty. The Honda dealership network around here has shrunk to the point that any dealer service is now almost a whole day affair so I would like to do my own service after the initial. Oil change is fully explained in the manual. Anybody know what is involved in the valve clearance?
