Ok this may seem like a total newb question.. just got. A 2015 monster 821 .. is there a gas gauge or just a light? I can't seem to figure it outback lol.. tia
No gauge low fuel light. When the light comes on there will be a count down function. Do you have the owners manual? You need it for that bike.
You can download one here:
