Just had the breakfluid changed and the fork oil changed gave the bike a test spin all good. Went back to the mechanic to pay and returned to bike no start. We taped the starter motor nó change. Tried push starting but no joy. The bikes light and start up lighting is working and no dimming of lights when starter button pressed. Tried the starter kill switch flicking over and back when started pressed no change.mechanic will check the side stand switch tomorrow. Any idea?

Side stand interlock? Would have thought the attempted push starting would have eliminated that as a potential problem.

Side stand switch highly likely. Try start with bike on centre stand and side stand up. Get in under and take a good look, you can get at the contact. DAMHIK. But I knew about it when it happened. Its the number one cause of what you have got.
Push start wont work with faulty side stand switch either. If you have a running K1100 it cuts out if you flick the side stand down.
It also makes sense as he would not have been at any of the electrical locations that give problems.

If you have the bike on the centre stand you can see the contact buried in the assembly, just move the side stand up and down as you look and see places that move. I had to bend a little tab and it cured it.

Not sure if the K1100 is different from the K100 electric circuits but:


  • If problem is kill switch related: Ignition on -  there will be no indication on the instrument cluster (apart from the ABS relay light blinking), head light will work normally but on pressing start button, nothing will happen and head light will not dim.
  • If bike is in gear (without clutch pulled in or with side stand down), instrument cluster will be normal when you turn on the ignition, but nothing will happen when you press the start button. If head light is on, it will not dim. This sounds more like your symptom, which points to a problem with the clutch switch (combined with not being in neutral) or the side stand switch. If the side stand switch is stuck (so doesn't clear the interlock when you put the side stand up) then that is a very likely cause of your problem. You should be able to disconnect it - just remember to put your side stand up before you ride off!

Another quick fix I use is to put a short piece of vacuum hose over the tab that depresses the side stand switch.

I put mine on centre stand last night and side stand down, exactly as you have when I turned on ignition. As you put side stand up you hear the fuel pump priming.

Yep side stand switch has happened once since my last panicked post.I would like to keep it as it is a good safety measure.is it possible dirt stops the switch traveling back to home position as it is so infrequent?

Thanks for all you help and sharing your knowledge. No start. K1100lt  502531
