Hi Terry
I have the same problem on my MC28 With the red light flashing. I believe it happened on mine because I removed the Neutral gear switch indicator placed in the crankcase's to change o-ring seal as I rebuilt the engine. (located by the Gear shift). The bike was fine before hand but once removing it I damaged it putting it back in not realising there was a split pin through the shaft that sat in the slot of the internals, unfortunately I didn't see the slot or split pin. When I removed it, it had snapped the split pin and had to make my own by cutting one down and refitting it. Unfortunately probably damaged the internals of the switch causing it not to recognise the neutral gear.
All the happens is I can't find neutral and if I put the stand down it thinks its in gear so cuts out. It doesn't affect the riding in anyway and have been doing for sometime. It is annoying but cant find the spare part anywhere so will have to live with it.
Have you removed or checked this, Do you have the neutral "N" come up on the screen still? Probably isn't this but worth letting you know. Something to try.
Ian
