Is the process the same for the 4V engines? what are the major differences.. is the reason it's so much more expensive because there are double the valves?

slightly more difficult - smaller space to work in, and more water cooled junk to remove to gain access (especially superbikes).

the four valve motors are not all that much harder to do the extra cost comes in the extra time to remove camshafts to make adjustments. And as Mitt said just getting to the valves.
Not harder just more labor intensive.

I always thought ducs had a screw type adjustment?  I guess I'll have to get my buddy to help me with my valve adjustment.  All I have to do now is get a 696!

No -- that would make sense. Therefore Ducati's don't have them.

Actually  some really do get screwed when they get their valves adjusted. [evil]

More labor intensive = harder.
No modification goes unpunished. Memento mori.  Good people drink good beer.  Things happen pretty fast at high speeds.

It's all up to your will level, your thrill level and your skill level.  Everything else is just fluff.

maybe I am being misunderstood ;)

The four valvers are not any more difficult to grasp the concept of what you need to do.
There are just more steps involved to make the adjustments. and then you repeat.....and repeat ......... and repeat........ and repeat.  [thumbsup]

I am doing a four valver right now and just putting camshafts in and out simply takes time. I guess if you really don't care about getting things "spot on" then you would not need to adjust much.
