I heard a pop then saw a plume of smoke...

I had just gotten off the highway and was sitting at a light. I was sitting at the light for about 2-3 minutes when I heard my bike go "pop" and saw a plume of smoke and my engine died. I pulled it to the side of the road and it started right up and got me home without any feeling of power loss. The oil level is the same and the color doesn't look contaminated and I can rev it up without any stumbling.

I did run into some rain on the way home, but I've ridden in the rain plenty of times with this bike and never had that happen to me. Anyone know what this could be? I swore I thought I blew my motor, but that wasn't it.

On the surface, it sounds moisture related.
The pop and smoke was probably the engine cutting out and partially burnt fuel exiting the mufflers.
At least that's my theory, since the engine restarted and made it home.
Unless you find something more tangible.

Does that mean I shouldn't be riding in the rain with the RC51? It doesn't look like there's a "bypass valve" on the intake as it's pretty much just inlet, filter, throttle bodies.

I was intoning that moisture may have caused an electrical problem to kill the ignition, but that it dried off enough to allow the engine to restart.
It's all theory since I wasn't there.

Because the frequent rains and high humidity here in FL, I took the precaution of putting a dab of dielectric grease into every electrical connector when I replaced my wiring harnesses.
It really does work to prevent electrical gremlins due to moisture and related corrosion.

When I removed my original buggered up harnesses, I found many a green contact from corrosion.
And where there's corrosion, there's poor contact and conduction.
It is ultra cheap insurance. One tube lasts forever.
