Let's see: I put a new valve cover gasket on. Old one looked find, did it for mental insurance. You will need a few new shims if you find any out. Hopefully your local dealer stocks them. Many Kaw dealers don't. Good news is that Honda valve shims are readily available at most dealers and are a direct fit.
Other than that, just some patience, good instructions, and a good torque wrench.
I have the full Service Manual, but couldn't have done it without Fred's excellent C-14 maintenance videos, [urlhttp://www.angelridevideos.com/concours.html][/url]
Good luck!
