Like the title says, the fans and fuel pump keep activating after the bike is off. This will go on for a good 20 minutes. I understand that the fans will stay on for a second after you turn the bike off, but I don't think it's meant to keep turning on and off for xx amount of time?
Troubleshooting:
- I disconnected and reconnected the battery to see if that would do anything, but as soon as I started the bike again, it continues.
-removed and reinserted the fuze for the fuel pump, and this worked, until the bike was started again.

Video of the issue is included.

McNair, It's normal for the 1125R. Just the bike taking care of itself: The fuel pump will cycle for a while when you turn it off on a warm engine. I believe the objective is to maintain pressure in the fuel line to facilitate start up. The cycling should stop once the bike cools down below a certain threshold.

Thanks, I was just concerned that it would drain the battery or something.

No doubt it would pull from the battery, not sure to what degree. If you are able to kick over after this occurs than its no issue.

The ECM programming for the fan and fuel pump has a low voltage cutoff, so assuming your battery is healthy it won't discharge to the point you can't restart.

I disabled the fans on after key off when my 1125R had a weak battery (it didn't take much to suck down the battery enough that the bike had problems starting) and left it that way, with no ill effects.

Oh heck, I don't remember off the top of my head. It was an options somewhere in the tune file--I don't remember it being hard to find. I have it on my old laptop, and can check tonight.

If you are using the simple ECMDroid it's in ECM parameters/fan settings.

You can set key off, fan off speed based fan control, and temps there
