fuel strip question

[gaz238]

my 2010 gsa fuel strip has now completely given up (yellow triangle etc) but quite happy to just use the trip, however does anyone know if this will cause any issues on my mileage or can i still rely on the bike to use all the fuel in the tank. i seem to remember reading somewhere that the fuel strip is needed to use the reserve tank

It will go down till empy.

In reality, from what I remember, with no signal the reflow and fuel pumps will run at 'full power', so that might shorten their lifespan.
Said that, I've ridden like that for quite a few years, no issues whatsoever.

I still use the trip to calculate fuel (I do have an adapter for the float but readings are unreliable) and calculate on average 10 litres = 100 miles. Never had major issues. Got stuck with no fuel maybe four times in the last 5 or 6 years (and 50k miles maybe).
I'm just careful on motorways as the fuel consumptions shoots up massively if traveling over 130kmh, but my bike isn't exactly stock.

Just let's see if someone with more technical experience can confirm. I'm 90% sure that's it, but... 90%.

The fuel pump controller does what it says on the tin. The fuel strip does not affect the running of the pump. The fuel strip feeds (via a resistive track, resistance proportional to fuel level) the fuel gauge, which has some software to calculate the reserve display (and range to go) - there is no reserve tank. With no fuel gauge, it is advisable to fill up at 250 miles from the last fill (and fill the tank) give or take a few miles. Or carry a few litres in a bottle for when everything grinds to a halt. I have tested all this out this year!

On my recent trip to the baltics if I'd filled up at 250 miles I'd have only put in about 22 litres.
There would still be 14 litres in my tank.
I used my tank as I should and filled almost every time at 390-410 miles. Range left still of 30-45 miles. Eack time I put in 31-32 litres. I still had 4ish litres in my tank.
I've said it before, a working fuel guage is needed on these things because of the difference you can get in fuel consumption.
Plus I hated having the flashing fuel warning on between fuel strips.
When I was in Iceland without the fuel guage working it was a total pain in the arse trying to work out how much fuel was in my bike. I didn't want to ride the trails with a full tank if I could help it.

Thanks.

Er-minio was saying that there was a reflow pump (never heard of that) and a variable power feed to the fuel pump? All seems like rubbish to me.

I have just fitted a bypass (fuel strip emulator from Motorworks) to my 2009 GSA. I use the trip meter to gauge refill times, so not worried about the fuel gauge showing full all the time.

The 'reflow' pump in the right side of the GSA tank is not an electric or mechanical pump like the GS and left side GSA pump. It isn't really a pump at all but uses venturi effect from the fuel pressure regulator return to suck up fuel from the right side of the tank. Maybe not the best explanation but it's late! Anyway the point is it has nothing to do with the fuel pump controller or strip.
My bike recently got blown over onto its RHS and the small amount of fuel in the LHS of the tank ended up in the other side. After getting the bike back up on its wheels it wouldn't start - FFS! Then I realised that as the LHS tank was empty there was no return from the regulator and so the fuel in the RHS wouldn't be picked up. 5 litres out of a can got it going and on the subsequent trip to the petrol station got another 28 litres in. There was probably a couple of litres in to begin with so in reality as many have observed the GSA tank is actually around 35 litres capacity.

The correct name for this kind of pump is " Jet Pump". They are used extensively in aircraft fuel systems and as Seahorse says, they work on a venturi principle with no mechanical or electrical input.

My fuel strip has failed again. I've had 11 so far.
The last one actually lasted since 2021 I think. I hope the new upgraded ones are better. Back to the dealer I go.
