You may be right on the unrepairable comment. The sealing ring for the compensating shaft was changed to a larger size in about '08 which should have helped eliminate that leak. BUT, I remember some of them leaking on the showroom floor. BMW said just ride it 50 miles and it'll quit. And I think most of them did. So to fix that one, get an '08.
As to the clutch cyl leak which has caused all your other clutch issues, BMW went to mineral oil instead of brake fluid on the clutch circuit. Fewer issues with the mineral oil version, but I think that changed by '05. One thing some have done is to drill a small hole in the tray under the clutch cylinder where it could leak so the oil can run out instead of contaminating the clutch.
The last two of your fixes are still under warranty...that's little consolation, but if you like the bike otherwise...
I have decided that there is no other brand for me. When a BMW is running, it's the best. I have been very frustrated by some of the stuff like putting 7 fuel gauge strips in the tanks of our K1200Ses...and loose cam chains...and having to put a chain guard in 3 of them at my own expense to prevent the engine from exploding...and having to change the key antenna once on the way to Wyoming, and once on the way to Oregon, both in gas stations...and endless recalls, I forget the rest of the crap, drill a hole here, change these bolts, upgrade this to keep it from dying on a hot day while riding up a steep hill on a curve in traffic, etc. I figure I just need to pay for the bike, and plan on paying for the bike again as I ride it.
But when they are running, they're the best
