R11S Electrical Issue

I have a problem that some may have experienced. I haven't ridden in a few weeks due to weather and job so yesterday I decided to take a little ride. First of all, when I tried to take off from idle the bike would die. Restarting a few times drained the battery so I recharged overnight. Today was another nice day so I jumped back on the bike with a fresh charge and still the same thing happened. My first thought was some sort of fuel starvation. Maybe gummed up injectors. I let it idle a little longer than usual then took off for the store. During the ride it seemed to lose power at certain times. Each time it stopped I could easily restart it. Made it to the garden center but was a little worried about getting back home. On the ride home I needed to make a few sharp turns and each time the bike died. I finally make it home and put the bike on the center stand. At this point I'm no longer thinking it's a fuel issue. With the bike idling I turn the handlebars full left. No problem. I turn the handlebars full right. The bike turns off. I repeat with the same result. Then without starting the bike I turn the ignition key to on and turn the handlebar to the right. All power is lost. Definitely an electrical issue. Turning right is pulling the plug on power.
So, the question to all of you is what wire, cable am I shorting by turning the bars to the right? I didn't have time to dive into it today but will this week.

Thanks

This happened to me too. The cause was an ignition switch wire breaking. I'd check there at the bottom of the key switch. Its an easy repair.

yup, classic ingition switch wiring issue. after you find the break, look to reroute it to gain another inch or so. some were delivered with the switch harness routed incorrectly, or just tied up too tight.

Yep, not a short at all, but an open. Some of these bikes didn't have their harness lengths cut too generously, and they pull, and over time, separate one or more wires at the base of the ignition. Bunch of threads on it. Some guys cut at least one of the factory cable ties to gain a bit of slack and ward this off. As has been said in several threads (but most don't do it, thinking it will happen to some other guy and not them) Check your harness!

there's a teeny, tiny little set screw in the key cylinder that holds the switch in. place a towel or some such under the bike before you remove it. Its likely that you'll drop it.

I probably will not have time to tear into it until Wednesday. In the mean time I'll order a couple of those screws...just in case.

Just an update on my electrical issue. You guys were right on the money. It was the ignition switch. When I removed it the break in the red wire was obvious. The sheath protecting the wire group actually allowed the wire break to make contact. As soon as I turn the bars the red wire separates and the bike turns off.


I managed to put everything back together without losing that little grub screw too. I even had enough energy to do a couple of other tasks I've been wanting to tackle like: re-install my power filter, hardwire my Garmin Zumo, re-install my new low HID ballast, replace several instrument panel bulbs and replace the hand grips.
