Mornin' Laurie, Bill, et al...
Greencan? You love old STs. Sounds like its mechanics are in better nick than that one doing all the yacking on the Forum! 
...eh, no on both counts. Firstly, my bike with the current need for disclosure actually goes and all that's needed to participate in another lap of Oz (if were so desired), is many tanks of petrol. And secondly, why would one want to invest in a bike that, on the surface, given the suggested valuations offered to Laurie, isnt worth a cracker.

I have made mention of this before in another thread, I know of a 1990 1100, which does need mechanical work, was purchase for $290, thats all. Now there in lies the paradox for moi, insomuch I believe the 1100 is a comfy and very reliable tourer, for which parts can still be easily procurred, yet value wise, is a dud. Interestingly too is the bike the 1100 was concieved to compete with, the K100 BMW will still command a higher resale price than an 1100 of the same year. Why? Praps the 1100 has still to find its place in history, I dont know.
What I do know is, my original 1984 Kawasaki GT750 P3, a bike built for the same purpose as the ST1100, is more sought after and in dollars terms, thus far better value for money than either of my 1100's I own. And both these 1100's are fitted with the post 1996 Honda ST1100 improvements.
Perhaps, Laurie would it be best if we got engine weeps sorted and got it back to a reliable running concern? Or consider Hobs's offer and do a Baz, n just move on. What say you?
As for moi...I am presently considering a 1940 HEC power cycle I have been offered...

Just a thought, or 2...the can :-)
