Greetings all;

As of this morning my low fuel light is on and will not go off. I have a full tank of fuel and have never had this happen before. I double checked to make sure I was not being forgetful, but the tank is full. Have turned it off and on a few times. Every time low fuel light comes on after a few seconds.

She runs perfectly.

Suggestions?
 
There is a fuel level sensor attached to the fuel pump assembly. May have gone faulty and it is replaceable. The part number is

887787.​

Thanks John. I will have her scheduled for a full service the middle of April so will see if the issue persists until then. Thanks for the heads up about that sensor.
 
Looks like the sensor is around US$100!!!
I wonder how you would test it. Probably using a voltmeter and check the resistance of the connector leads with the sensor dipping in fluid at various level?

When I rode home last night the light stayed on for about 3 minutes and then went out, and has not come on again. I did replace the battery with a new one just before the ride where the light would not go out so I wonder if that could have been an issue somehow.

Still running great, and no light today. Will see if it does come on when it is supposed to. Not an issue for me as I track via ODO anyway.

That's too funny. As a joke I almost said have you had your battery load tested.

A new battery has been known to correct many electrical issues.
 
If the new battery was not fully charged before installation, the system voltage may have been low until the bike was ridden enough to get the battery fully charged.
 
As John says above, and my recommendations based on decades of experience also, it's best to let them sit overnight to absorb into the plates before putting any charge voltage on them. If Yuasa, they do make factory prepped versions that are ready to plug-n-play out of the box (which are a little more $), but worth it if you're in a rush.
 
Thanks for the added info guys.

I do believe the battery was prepped properly, as the bike started up instantly and has continued to without any hesitation. But it’s good to know for the next time I have to put a battery in to bring it home and put it on the charger first after having let it had an additional night to sit.

Again as always these forums are a lifesaver and all of you are absolutely wonderful.
 
It is indeed a peculiarity that one of the most critical components of a modern motorcycle, the battery, is so misunderstood or not given the level of respect and attention to detail that it should receive. 🧐

Isn’t it truly amazing how many issues here work their way right back to the battery? 😀
