The things I learnt today.

[Squeakers (formally SlowRider)]

Today I learned some very valuale lessons.


I learned that when your ST has 50km where the km/L is normally displayed that means time to start walking. Apparently 50km to empty should be read as "time to ride the foot Falcon"


I also learned that you can get 27L of fuel in the 1300 when there aren't even fumes left to burn.

Yep, had the same thing happen to me. Left the gym (had to throw that in) with 40km left on the gauge and a short ride up Windy Point road to Belair to fill up. Great little road. Fanged it up, passing push bike riders all the way --- until cough, splutter -- stupid gauge said I still had 40km left. The bike riders were nice when they rode past me.

O' no, nothing worse than the a glory run then eating humble pie as people go past. Haha

Have put almost 28L in once, that was pucker time!

I'm lucky the day I found out I wasn't in a hurry to get somewhere.

It's an experience you don't need on your bucket list. Lol

28L..wow... your STeed was thirsty that day. Lol

I think the problem occurs because the gauge tells you the estimated distance left based on the historical fuel usage rate. When the bike is restarted the engine is probably cooler, or even cold, and uses fuel at a considerably higher rate until it warms up. You also use a lot more fuel when accelerating away from start compared to cruising. The display blanks out at around the 40km to go mark because a change in the riding conditions can make the average fuel usage meaningless.

That sounds right.

I'd love to be able to adjust it down. Having the bike show empty with a litre left is so much less of a hassle than a gauge that says you should've filled up a kilometer ago.

Also, the bike was letting me know it was thirsty when the display started flashing. So it's not like this jumped up and bit me on the arse. I had the choice to stop at one of the eight fuel stations I passed. But when the bike first tripped over from km/L to distance to empty (75km to go) I watched the odometer. I got just under 30km before it died at 50km to go.

I was carrying 5 litres in a jerrycan on a ride down the Bruce Highway towards home and was curious how accurate the estimate was.

Mine was set to display usage in litres per 100 km, and switched to range mode at 99 km, so I checked the Odometer and continued cruising at highway speed.

At 40 km range the display changed to -- and I'd traveled a further 60 km from the start of range mode.
A couple of hills on the Bruce north of Nambour must have changed consumption and at 97 km the first cough, quickly followed by the 2nd, 3rd and final cough just after the crest of a hill east of Nambour. I quickly pulled in the clutch and put out in neutral and coasted to the bottom of the hill to a flat spot to refill, 98 km from going into range mode.

Another time, after already hitting range mode on the 32 km ride to work, I chose to fuel up at the servo near home. Despite being at 85 km range at shutdown in the morning, it quickly dropped to 50 km by the time I was halfway home, and went to -- display before I got to the servo.  this was a trip on the Gateway motorway in stop- start traffic and lane filtering.  From memory I put 26.8 lies in that time.

I think that reinforces the theory that cold engines and changed driving conditions severely stuff up the range calculations.

I have only once on my 1100. Just to test the low fuel warning which I suspected had failed. It had and the bike ran out of fuel but not an issue as I had 10 litres spare waiting in the side case. Until I fixed the issue I wouldn't let the gauge indication go into the red.

I trust my car's estimated distance though. Had it down to zero once or twice and it still goes.

..... I also learned that you can get 27L of fuel in the 1300 when there aren't even fumes left to burn.

I've put over 29 litres in my ST13 "29 Litre" tank, after 80km to empty popped-up on the dash, and then riding around 85km @ around 80km/h dropping to 60km/h, before finally reach a servo.

Another time (not quite stretching my luck as above), the tank only took just under 28 litre (lapping at the filler lip).

Another time (on one leg of the ride to Wooli last year), I could only get 24 litre in the tank (lapping at the filler lip), after riding 530km.

I figured that these differences are due to the top tank not properly feeding fuel through to the lower tank - most times it feeds quickly, others slowly, occasionally it hasn't.
