Gents i think i have an issue with my starter motor which i am going to remove to clean and check the brushes as a matter of course[even if it turns out not to be the issue] while i am at it i would like to reroute the cable correctly as at the moment it comes behind the coolant bottle and across the battery which i dont think is correct, does anyone have a diagram/description of where it should run.
many thanks

I’m sorry to say that I can’t advise you of the correct starter cable routing, Paul. I would have taken photos of mine, but I haven’t seen my 1300 for more than six years .   The bike is in a storage warehouse a long way from home.
I don’t think the factory service manual will help you either.

Not sure if this helps but I took some pictures that show the earth cable when I fitted a Shindengen regulator.  The airbox and carbs have been removed which shows the earth cable attached to the back of the block, passing under the battery tray and feed up next to the battery on the left of the bike behind the battery. 



However, I also have had issues with the earth cable so have fitted a second cable - the orange wire in the pic below.  This is connected to the block via one of the accessible crankcase joining bolts on the left side and then feeds under the battery tray as before and up to the battery terminal.



I have also had issues with the original starter motor - sluggish turnover, particularly when hot.  I measured the starter motor current (using a current clamp I borrowed from where I worked) to compare with the starter motor specs - turned out that the motor was drawing about twice as much current as it should do due to a short in the windings - drawing more current but producing less magnetic field and therefore torque.  When the motor gets hot, the winding resistance increases, reducing the current in the few windings still working normally, resulting in even less magnetic field and lower starting speeds. A new starter motor (some suppliers also offer a rewinding service?) solved the problem inmmediately.

so why is the 1300 locked up in storage? Normally I would send a PM but we seem to have lost this feature ?????

I bought the bike as a project. At the time, I had an offer of the use of a garage as a workshop in which to restore the bike. That offer fell through.  Trying to find a suitable garage to rent, with electricity, and a convenient distance from home, is nigh on impossible. Plenty of small commercial sized units, but way out of my price range.  I keep thinking I might sell the bike.
