11000 miles on a 01 bike that's a good find for sure, there's a good chance the TPS hasn't been moved, one way to check is there white paint on the bolts? Not a absolute but a good indication.
All the cylinders should be pulling the same spec range of Hg once correctly set and balanced. Theoretically carbs only go out of balance due to slight bedding in and wear overtime and due to atmospheric conditions, the former is slight later is very slight, in reality what buggers the balance is mainly people messing about! At 11000 there's a good chance all's well, unless I've missed something you don't say why you are doing a crab balance, is it too see if that effects your cam chain noise?
As for the 5k on the tacho, it will only go into 3 positions 0, 5k or 10k as long as it's in the middle it's fine. The TPS is pretty much as you think, it allows the ignition module to select one of three basic timing settings for a given throttle opening, the bike doesn't have an ECU, although many think it does, it doesn't. They can be temperamental, that said in my experience (now watch the flood gates open) they only go that way when messed about with, or jet washed. Most FZS600s these days have had several owners and many a hard life, even if they look clean and reasonably low milage, so they get played with and jet washed!
If you do have TPS troubles you'll find Yam OE are very expensive. But other bikes Yam bikes share same one as do some cars, off the top of my head it's Suzuki bikes and cars but can't remember which, it's been a good while since I've changed one. Someone will pop along with which I've no doubt or do a forum search or google search the part No or Yam bits for about £100 ish.
