I recall reading (but can’t remember where) that the GV650 has a fairly generous reserve tank. (Mine is from 2007). I have looked all through the manual and can’t find any info on using the reserve tank. In my old days of biking you always had a tap below the tank which had on – off – reserve. There seems to be no tap. So when the tank level indicator goes down to zero will I be totally out of fuel or will I have a reserve available?
The 125cc models defintely do , but for GV650 i would say most models now just drink the whole tank down to zero but you would basically keep an eye on the fuel gauge bar as it can be optimistic!
2 bars left usually means “Fill up now!” , as i have learned the hard way haha
