Wow, this thread is [dangerously close] to that famous thread of yore, 'What are the most common size shims used in a valve adjustment'.
Scared me a little when I first glanced at it....
You really do not need to much to do a valve lash check. The valve cover seal maybe although I think you can use them over again, check the O-Rings on all the oil pipes under the valve cover, and check the spark plug well seals. The seal on the side cover you have to remove is just an O-ring and is reusable. After that, the real hold up on this job is waiting for any shims you may need unless you have a well- stocked dealer nearby and they are willing to play the old 'let's trade shims' game.
Depending on the mileage of the bike, it can be a great idea to combine as many major maintenance items as you can as you have to strip the bike pretty far to get to the valve cover. Common items are spark plugs, a Throttle Body synch. and the air cleaner while you are that deep into the bike. Coolant changing is also a good idea as the fairings are already off.

I would like to try a valve adjust on my bike. I have only done my klr650 once. I own all 2 strokes and this will be my first major foray into a modern bike with valves:). What parts am I gonna be needing for this? I called a dealer here in Tucson yesterday and was told just $660 for labor alone for 6 hours and $200 for parts. Will I may as well give it a shot at that price . I know I need a valve cover gasket but what else possibly? Do I need to replace the grommets for the cover bolts? Thanks for any help
