How to check valve clearance?

Does anyone have a good link or directions as to checking the valve lash of the SD? I'm state-side and the dealer network is non-existant where I'm at, and my bike is due for a check. None of the other dealers around here would check (they saw the KTM logo and wouldn't even remove the rear wheel for me once), so I'm pretty much forced to do it myself. Any help at all would be much appreciated regarding tools, parts removal, etc.

Whoops just found a thread here giving details on how to do it. Was in the technical section and I figured it'd be in the How to do it. I'll give that a good read

Where are you located that there are no KTM dealers?? Just curious!!

it's straightforward enough, I did mine last year, luckily with no need to re-shim
