1 Clutch will not disengage Tue Dec 25, 2012 3:43 am

Merry Christmas all.
I have "inherited" a K100-RT, sold as a 1985 model, but VIN plated as 11/84 build and RealOEM shows it as 10/84 (serial number in my signature below). When my father had his hips replaced, he decided that he could not risk having a lean-over incident and he put it away, with a good deal of care to prep for the storage regarding fluids and flexible parts.
I recently retired and returned from being stationed overseas and have been working on getting this baby back on the road. I will apologize right up front and admit that most of my "knowledge" on this process has come out of a 1988/1989 set of Haynes breakout books and some friendly consults with my local parts counterman, along with this and other forum accessed as web search results.
All of the fluids and filters are brand-new. Since a stabilizer had been added to the fuels and the system had not been drained, I took a good look in the tank. The pump rubber seat was gummy, as well as some hoses so I dismounted the tank, rebuilt/replaced the entire fuel transport system down to the fuel rail, and up the other side through the regulator, adding a little extra insulation as suggested by my local guru. I bruised up my forearms a bit making sure all of the varnish was out of the tank, but my efforts seem well spent, after a bit of coaxing to get the juices flowing, the engine is now running like a top. I also rebuilt the front brakes' master cylinder and now all of the various functions of the bike seem to be nominal -- except one.
We can not get the clutch to disengage. The transmission shifts up and down on the stand through each gear very well, the LCD display agreeing with each lever actuation -- the power is making it through the drive train just fine. However, it will not clutch out. I have tried "brute force" assessments as mentioned in other postings (using the brake, not my hand), but it is really solid. I have measured out the cable inner wire and it appears correct at just under 3 inches. The release lever provides healthy spring resistance and return, but I understand that is could be more indicative of the coil spring and not the state of the mechanisms through the diaphragm spring. Unlike similar postings here, we have not had the clutch apart, so it is not like it could have been improperly reassembled.
To me, the implication is that the clutch will need to be replaced. I have no problem with that fact, however, we are not jigged to do that kind of work, judging from what I have seen in the various forums, with alignment tools that need to be "re-engineered and re-machined in order to work at all." The most we would seem to be able to accomplish would be a tear down to the level of separation necessary to do a spline lube.
My question to those assembled, is it worth it? Is there some other step I can take to try to regain de-clutch functions, some other mechanism in between that can be causing this? The biggest issue I have is the knowledge that if I will have to pay someone to replace/renew the clutch properly anyway, does it make any sense to crack the drive-train open myself ahead of time?
