I went for my first ride in 4 months and throughout the day my fuel level indicator would periodically flash. Any thoughts on why?

 

Is the level low?
Mine flashes "FUEL" on the display and the orange Speedo needle also flashes with the tank is low....
No reserve so this is the way to warn you................
Does that answer your question....Hope that helps.......
.....Caper.....

 

could be the sensor. there have been issues wit the fuel sensor. i had some issues with mine. so i took it out and moved the flot a few times and re installed i have seen no issues lately.

it dont have a res??? my 08 500 did and so did my 00 335 did.....

 

hopefully the sending unit in the tank isnt starting to have issues. check wires for any cracks or corrsion.

 

It had a full tank. I think it may have stopped later in the day. Maybe the sensor just got stuck because it sat for 4 months with very little fuel.
