What a fantastic bunch you all are. Thanks so much, not only for taking the time to read my tragic tale of woe but also for all your comments, suggestions and advice. I didn't expect to so many replies, especially that quickly.
With regard to the cruise control, I did have a new rear tyre fitted just before the problem started so I guess that they may not have been familiar with sensor settings. The mechanic I used has a first class reputation in the area and a lot of our Ulysses members use him. The trouble is he is so busy that he lets his apprentice do a lot of the work. Anyway he charges like a wounded bull so I have now changed. My new guy is not cheap but he charges much less than the other place (NO NAMES NO PACK-DRILL).
The suggestion about doing my own maintenance is a great idea, even if it is only for the basic stuff, I will have to look into that and try my hand at next service.
One thing that concerned me about the original company was that several times I got the bike back and the cowlings were incorrectly replaced with edges overlapping the wrong way and fastening pins loose or missing. Anyway enough of that or I will get a reputation as a winger.
As an aside, A mate of mine, Bob Brewer ( Also an ST1300 owner) and I are tentatively planning a week to ten day trip to the Snowy Mountains before it gets too cold. He will take his trailer and I will take my tent. Weather permitting we hope to take off around the 15th or 16th of this month although knowing Bob, he is just as likely to cancel out at the last minute due to business pressure. 71 and he still runs his own company ( Professional Traffic Solutions) and he can get called away at very short notice. Anyone looking for a good business, I believe he is thinking of selling.
