The only hitch is that the bike winds up sitting, partially disassembled, waiting for the shims. Not bad if it's your bike in your garage, but since it's your buddy's, just make sure you are aware of that.

One dirty little secret: they hardly ever need adjustment. Lacking heavy springs, the desmo gear places very little pressure on the components that wear, causing the need for re-adjustment in other valve trains. You can probably go for years just checking without ever re-shimming. In 70,000 miles I've actually only had to re-shim twice.
You know what, that's exactly what I suspected. The dealer here charges an arm and a leg and it's actually only an estimate depending on how many valves need adjusting!
When they told me that, I knew right away that most of them probably don't need it and they just run a feeler gauge through it and call it a day.
