Not to post an old-school bike related question or anything, but:
I was browsing my CRF owner's manual, boning up for my upcoming spring
change. Krike', those Showa forks sure are complicated. Which of the
special tools do I really need? It almost looks like a good idea to
buy a top cap wrench. What about the special spacer/holder that you
stick under the compression valve when you pull it out? They give a
measured drawing to make one in the manual, but it looks like an
adjustable wrench slipped over the damper rod would do the job just as
well. Man, the entire assembly has to be taken apart just to change
the fork springs - how silly is that? I guess I'll end up doing the
recommended 3 hour fork oil change, like it or not.
Any hints I should know before I start cracking these things open?
I just looked at the carburetor breakdown in the "adjustments &
tuning" section. That thing looks like it belongs in an F-22 Raptor.
Ugh.

Somebody local made a combination wrench for these 2 task. Aftershocks
may still have one available or Zoom Cycle in Santa Clara, CA.

You poor bastard. I have nothing to offer but my sypathy and pity.
Sometimes technology is overly complex for the task at hand.
I helped a friend change fork seals on one of his CRF forks. After taking
hours to do one fork, I gave him the handful of special tools we had used
and sent him home. Fragile valve trains, impossible to access carb, and
overly complex forks are pushing a lot of buyers to 2-stroke KTMs.

Oh great, I have a pair of THOSE on the other bike. Bloody hell.
Ironically enough, the best fork action for the riding I do is as
close to wide-open valving as I can get. All of this high-tech
gobbledygook is pretty much wasted on me. I'm beginning to actually
appreciate the WPs on my GG - now THAT's scary!

That's a terrific post - thanks. Man, I have to do all of that except
the tube seperation and seal replacement just to change springs.
F**k. I have to say I prefer the 'remove fork caps, pull out springs,
drop in new springs' 5 minute procedure on all of the other forks I've
owned in the past. Oh well, another weekend shot to hell.
Alright - I'm convinced. I need to invest in one of those big fork
cap wrenches. I'm also going to need a good-quality hyper-tolerance 6-
sided socket for the compression nut (51 ft-lbs...yikes). Those
things scare me - I'm still shellshocked after seeing the flurry of
aluminum schrapnel poof into the air from a stuck compression nut when
I was blasting it with an impact gun - 6-sided socket and all.

Just this morning I read an interesting quote on another forum. The
poster suggested that the rise of KTM in terms of off-road wins was
directly related to the Japanese manufacturers all switching to
aluminum frames. He mentioned Yamaha's number of off-road wins before
and after aluminum frames as a reference. For the record, he owns an
aluminum framed Yamaha and a KTM.
Not really relevant to your point, but I figured if you're going to
become an elitist you should be armed with all the ammo you can
get. 
For my ability level, I doubt the frame's performance is much of an
issue, but the maintenance issues you mention are a very real concern
to me.

Good stuff! Does the bike come with a special manual or something?
If I buy one, can I opt out or do I have to get on board with the
program?

Aluminum frames contribute to global warming, IEDs, and spontaneous human
combustion.
Japanese bikes come from the factory with used fish oil for suspension
fluids.
Steel is real. Bikes of Northern European descent are more pure.

Sir, I do believe you meant "whale snot".
My XRL still carries the factory fork snot.

The Showa's aren't that bad once you have done them once. I made the tool
that you need for the bottom of the fork. You do need that and a tool for
the top of the fork, they will make your life easier. Bleeding the inner
cartridge is easy. I have worked on Dan's Kayaba twin chambers a few times,
and they are horrid to work with. Bleeding the inner cartridge on those is a
pain in the ass, and you still end up feeling like there is air in them.

Any of the the non-twin chamber forks are easy to work on.

It comes with a bottle opener.
Because their service manual is so superior, they will charge you $67 for a
CD version. <GACK!> (I still owe Bruno a case of beer. )

I'm still a little fuzzy on the details, but I believe that you need to get
at least one orange tatoo and start wearing orange underwear. Not sure
about the salute/handshake thing.
