Hi, Mike --
Is this your first post? If so, welcome to TT! If not, forgive me for having missed your previous one.
I'm a little hesitant to post this, because I'm a newbie to biking, and there are a lot of very smart, very experienced riders on this Forum.
But my 2013 Bonnie sometimes will not start up after stopping for gas or just shutting it off for a few minutes. First crank of the day, it starts right up. But sometimes on a subsequent start, it cranks just fine but just won't fire up.
I finally checked my owner's manual -- it says that a restart is done with the choke engaged (out), even if the motor is warm. WHAAAA'????? Sure enough, the next time I rode, then stopped for gas and it wouldn't start, I pulled out the choke and it fired right up.
There was a lengthy discussion about this on the Forum, IIRC, and it seems illogical to me if the engine is warm to have to choke it. But by golly, it works on my bike.
Maybe give it a try and please let us know what happens or what you find out.
Thanks, and welcome aboard!

Mike 
to TT, glad to have you with us, that same thing happened to me about a year ago, after i pulled the spark plug out to check for a spark i traced it down to the kill switch, i must have bumped it in the off position. Talking about feeling like a idiot. Let us know what you find out.

All was well until it refused to start because of an ignition failure. It suddenly lost spark. I need info on how to trace the fault. Failed component, broken wire etc.
Mike, start with the fuse, then go to the spark plug, follow the circuit back to the ignition coil, you might just check the coil first to see that you have a hot ignition wire there. I am not that well schooled with the newer electronicics but just try to trace the circuit all the way to the control module. Make sure all of the limit switches (kill switch too) if any are not tripped. If you are not getting any fire to the plugs and the wiring has not been molested then the ignition control module, coils, electronic pick up may be bad, its almost a hit and miss unless you can get your hands on the information that is needed to test these components. Also make sure that the battery is in good shape, some of these systems will not give you correct information unless you have a good battery, for example i worked on a Chevy Blazer the other day that would not shift out of first gear because the alternator was bad, so keep in mind that electrical components are in a world of their own! Good Luck
