Fuel light

On a C800 (no fuel gauge).
Just wondering, how much fuel is left when the light comes on? Also will the light flash or anything when its really low?
Noticed mine come on and off, seemed to be when going up/down hills, but it hasnt stayed on constantly yet.
Odo reads about 130 miles or so.
Thanks

Depending on how you ride? you should get around the 170/80 Miles per tank average, less if ridden hard, more if taken easy, if you use 30 miles after the light has come on to get fuel you should always be fine.

The light will blink randomly a few times before it comes on properly, that's just the sensor being confused by the petrol temporarily leaving it.

Dave's usually flashes around the 100 mile mark 

Dave flashes at any time!!!!!
