In time, I may do a how-to with photos here, but for now I wanted to quickly note the valve lash spec range below, and note that the very first V100 we've had in for service @ 890 miles, had two (2) valves that were tighter than the spec'ed range. We check them in my shop every time. Doubt many dealers do. Don't pretend. Downside is how complex of a job it now is (FFS Piaggio).
