I have owned my 1997 'Taxi' K1200RS since December 2004 and have absolutely loved it. In 2011 I bought a K1200S which has now been replaced by a K1300S Motorsport - which was going to be part-exchanged for a Triumph Tiger 1200, all ready for my retirement next year.
One 'last' ride told me that I was not quite ready to lose the K13, so I kept it and retired (for now) the K1200RS. It has been garaged all winter so yesterday I fitted a fully charged battery (green light on Optimate) but it would barely turn over. So I carefully jump-started it from a running car engine battery, put the seat on, ran it around the block and kept it idling until the fans kicked in. Gearbox, clutch brakes tried. All perfect.
It nagged me that it wouldn't start on a seemingly fully charged battery, so this morning I tried again, having charged the battery to full. Again it tried to turn (very sluggishly) but did not fire. So I released the starter button and turned ignition off - but the starter continued to try to turn with no ignition and without the starter button touched. So I whipped out the battery as fast as I could, feeling dreadful that I'd damaged the old girl. . .
I seem to remember reading on the old i-BMW site about this - have I melted or welded something on the starter solenoid? I would be very grateful for advice on this, and how I set about fixing it.
My plan is to still sell the K1300S Motorsport (anyone interested? In East Yorkshire, 12,000 miles, showroom condition, clutch judder and hot start fully sorted under Bowker's warranty), and to run the RS alongside the Tiger.
Update - Having read other posts, I reckon I may have fused the starter relay. Can a battery still be 'weak' somehow, despite showing green light on the Optimate?
