After being K-less for about six weeks Low Flying Brick fired up again this afternoon. I've done the tappets (five out of eight needed replacing - one exhaust was down to 2 thou!!) and that's made a real difference to the sound of the engine. I also made a complete new wiring loom which was modified from the original diagram to suit the Honda switches; that's by far the most complex loom I've ever modified and built. I made a couple of errors (it does help to provide power from the starter relay to the rest of the bike for instance.... ) but nothing that was difficult to track down or fix.
One thing I discovered along the way: BMW seem to have used two different AMP connectors on the FICU at different times. I bought a secondhand '85 K100 wiring loom to strip for the FICU and ICU connectors (they're not available new from AMP) and assumed it was the same as my '83 one. Not so. The hooks on the nose of the plugs are slightly different shapes, the '85 one has two small locating strips molded on one side and the '83 one has a locating strip molded into the socket on the FICU. Three snips with the wire cutters later and the '85 plug now fits the '83 socket securely.
But! it's not quite finished yet. I still have to reassemble the bodywork and heat-soak the engine so that I can balance the throttle bodies again. It'll be done by next weekend - I hope! - then I can put the Bandit back into its obscure corner.
