Hi all, hoping that someone can offer some advise on what may be the cause of the below.
My 2011 660R hasn't missed a beat, that is until recently...
Few days ago whilst on a ride into town I noticed a sudden deceleration whilst cruising in traffic on about 60kmhr (only for a split second), like a misfiring.
Then nothing for last 20mins there. Then on way back (after bike turned off for 15mins), happened again, and then again few minutes later, then again, then bike just died (whilst cruising in traffic).
Pulled over, turned off and back on and restarted and idled in neutral no problem. Then every time I tried to put into gear it would instantaneously shut off. Like it would if the stand was down (which it wasn't). Didn't matter if trying to get into 1st or 2nd gear from neutral - same thing.
Checked the stand sensor and seemed fine and not stuck in.
After 20 or 30 mins tried again and this time motor would stay running when clicked into gear.
So took off again but only got about 20mins up the road when same sequence of events and then just died again.
Was almost home so pushed last bit and I haven't tried again for few days.

Has anyone experienced this before?? Could a faulty side stand sensor cause this? Or something more serious. Strange that after cooling down it would go again though...

I have minimal mods, K&N stage 1 and 2, kevs fuel mod ( the one with that's adjustable, richens in open loop I thick)

Many thanks, Nate.

From the symptoms you describe I would definitely be pointing an accusing finger at the side stand switch.

Check the wiring carefully, they can wear through at various points. Remove the left-hand side panel and trace the wiring all the way back to the connector. Unplug the connector and using a multimeter connected to the two terminals of the switch side of the connector, check the switch operates as it should and there are no funny readings. You should get a simple 1 or O when reading the resistance/continuity.

If you find a problem and it's the switch, not the wiring, then you could try cleaning the switch as best you can with contact cleaner. Otherwise it'll be a new switch.

For the time being though you can cut off the switch and solder the two wires together, or scotchlok them together, to provide a constant connection to keep you on the road in the mean time. This will fool the start inhibitor system into thinking the stand is up all the time. Be wary though that the bike could be started in gear on the stand with disastrous consequences!

Thanks for the reply Pleiades, will follow your advice. Hopefully just faulty side stand sensor wiring.

Just to close this one out, I removed some fairing and traced the cable up to the connector and found that the connector was coming loose. Clicked it together and added some trusty elec tape for good measure and good as gold.
5min job in the end.....

Cheers Nate.
