Default Cooling fans.

Took a ride yesterday, and sometimes when I get back home and shut the bike down the fans on the left and right lowers run for a minute or two then shut off. Yesterday, I shut down the bike, and only the left fan is working. Ran a bit longer than normal, as well. I took a screwdriver and turned the blades on the right fan, thinking maybe it’s stuck or something, but turns fine. Is this a normal thing with the M8’s it’s never done this Borge so not sure it it’s an all of mine situation or if the fans are independently operational of each other. Thoughts?

They run independent. To test fan operation, turn the run/stop switch on, then ignition switch on. Without starting the bike, roll the throttle past 1/2 way open, and hold it there for a few seconds- you should hear the fans kick on. At this point, you should be able to determine if both fans are running (you'll be able to hear them, and feel air movement from the outlets)- if so, key off, all is well. If not, key off, & schedule some shop time.

Ran the test. Both working as advertised. Strange that they are independent of each other, though.
