One owner from new, nearly 300,000 klms this bike is one of the most unmolested original machines (for the work it has done) that I've ever seen.
There was really very little actually wrong with Duncan's bike. Of course there is wear and tear after more than 30 years and nearly 300,000 klms, but this bike has had repairs and maintenance carried out religiously and meticulously all it's life. It has the kind of patina that made people who came to visit me at the shed stop and admire it.
As with any old thing you could make a call to just go for it make it new again.
Or.. you could assess the bike and map out a plan for an ongoing work schedule over a period of time (must do, should do and could do). With this, I could give Duncan a set of priorities and a bit of a budget to aim for and to keep the bike (and his other half) well and happy for the next 30 years (I've run all my businesses this way). Duncan chose the later.
I had the bike for a week or so but just worked on it as I had the time to spare (so 6 hours in total).
I did a compression test first up, dry and wet, and made a list.
The main problems were the carbies, rubbers and the plug leads and caps which were original and crook. The compression was good and the leak down test didn't reveal any real issue with the valves although the tappet clearances were a bit tight for my liking. There were a good few little issues (some time worn and dirty electrical connections and a few other bits and pieces like throttle cables that work through a splitter...grrrrrr) which, when all combined made the bike a bit flat.
Any way, I guess in part, because it had never been butchered, it responded beautifully to my fettling and just purred. This is the reason I am starting this operation and not retiring. It is something I really enjoy. After the 6 years as a consultant, project manager living away from my home and my wife and my family, I don't think I can explain what a joy it is to sit quietly in my (ahem) rustic little shed, listening to my fave music and fixing my fave things. :)
