I have a '08 1125R and the low fuel light comes on along with the check engine light (it has a full tank). I have to set my bike up to ride one-armed (right side controls). In doing so I use a right sided clutch (aftermarket) so the side stand safety switch is disconnected seeing there is no place to plug the wires into. Also the the front brake line gets rerouted to the back brake pedal, which leaves the front brake switch disconnected and I also disconnect the back brake, and only use the front. I took it for a short ride this year and the lights seem to come on when I get on the throttle.
Will any of these open circuits, or disconnected back brake line set off these warning lights?
Or do you think the stock voltage regulator
could be the culprit?
If it is the voltage regulator, is the CE605SB regulator the best option, and how would I test to see if the stator is still good?
Any Help is much appreciated!

Wow, are you saying that you will ride your bike with one hand/arm? And use your front brake only for slowing/stopping?

Regarding your lfl, or low fuel light, I'd say ride it for a while and report back. It will take 50 start cycles before your DTC (diagnostic trouble code) will clear.

The LFL/CEL combination has two causes.
Either you have a bad sensor for fuel level or an old rev firmware in your ECM.

From the controls you describe the 1125R is a VERY BAD choice for a M/C.
I would strongly suggest something you can get an automatic or semi-auto trans and eliminate the clutch.
For brakes, several companies make proportioning valves to send 60-40 or 70-30 pressure to front-rear brakes.

Whatever you choose I hope you are safe and enjoy the ride.
