The difference between a "check" and a "check and adjust" is the length of time it takes to add/subtract, plus remove and replace 4 bolts, plus another few minutes to actually swap the shims, replace the buckets, and re-align the the timing marks.
I'm a total noob shade-tree mechanic and I did my valves by myself in about 5 hours - and that was really, REALLY taking my time and carefully observing how it all came apart, labeling parts, etc. so I could put it all back together. I also had to remove crash bars, and I also pulled the radiator.
Seriously, if you're mechanically inclined (and interested - it was 'fun' for me) you ought to try it yourself. There's plenty of help, walk-thrus, etc. online (right here).
If that's your idea of torture, I'd stock up on some chicken wings and beer and find a local owner who would do it just for the lulz.
EDIT: oops - that's on a Vee, which has gear-driven camshafts. I think the Wee might have chains to mess with. Here's mine - notice the exhaust cam cover jobbie has 4 bolts - the intake's already been removed in this pic, and the camshaft can literally be lifted right out - the buckets are right underneath and can also then be lifted right out (with a magnet), the shims are just little pucks that lift right out.
Takes much, much longer to strip the bike down (remove tank, plastics, etc.) than to actually do the valve 'work.'
