hi,

I realise this question has been asked before, but am searching for an answer asap as am currently in Buenos Aires meant to be heading south tomorrow.

My bike the BMW F800GS has decided to stall/cut out as if its out of fuel (which it isn't).

it only seems to have happen since arriving in south america and the heat, it tends to happen at lower speeds and is ok(ish) at high revs, but around town always cutting out.

Usually if i leave it for 5-10 seconds and start it with some throttle, but soon after cuts out.

Any suggestions and solutions would be appreciated.

cheers

joe

if any

googling 'f800gs stalling' brings up a pile of threads on AdvRider and elsewhere.

Could be fuel pump or even side stand switch.

thanks tim, will try the side stand first, moving onto the fuel pump if the first doesn't work

Clogged fuel injectors are the other common cause and some have had success by added techron or seafoam fuel additives to their bikes.

Hey mate!
Good to see you're there! Unlucky you're havin troubles! If you installed fuel filters...are they getting hot and vapor-locking? Solve by adding insulation around them to shield from engine etc.

Otherwise see if when you put it on prime if it runs...if so perhaps your vacuum line is blocked/not working.
Good luck!

Prime? I had two of these, troublesome little buggers, nice to ride though. Sounds like the symptoms of a failing fuel pump but I thought the F800gs was pretty sound in that department. At the risk of sounding like I'm stating the obvious, I'd check all the fuel lines, etc for any damage and check sensors for corrosion or blockages. I'd check the plugs too and the connectors, wires, etc. I'd also think about air filter in case that was blocked. It might not just be fuel starvation, it could be anything to do with combustion.
It just occurred. I've not had one of these for a while and can't remember but on my G650 there is a way to reset the computer by working the throttle before turning the key. Maybe there is a way to reset the computer on the 800? Definitely worth a try. Maybe someone knows how to do this or even if it can be done.

Good luck.

Have a read of this thread re an F650GS twin--it ended up being a fuel pump problem.

Same problem, different thread on AdvRider but might be useful for other pointers
total power failure f650 twin - stuck in khartoum - ADVrider

Good luck.

Thanks to everyone for the advice, have ended up replacing the fuel pump, driven 1500km intp patagonia, so far no problems!!

Glad to hear you're back on the road.

I have an 09 gs 800, me and some friend were out in baja, last year, and i encountered the same issue, lucky my buddies were there to help sort out! On start up,it would run for 10 sec. or so, then die! Yes, like fuel pump issue,it was so to speak, we check to see the pump was pumping fuel by removing fuel hose and fire it up for the few sec, it would run, and sure enuff it was pumping fuel, On the gs800, the fuel pump is in two stages, 1 is the primary stage to pump,,,2 is secondary stage to keep pumping, what we found out is if you take a wire, strip at both ends , and stick one end to your 12volt power source ie@your batt, tender lead, and the other to the belive it was the blue/yellow plug in lead going to pump( its been awhile) i think its correct tho,,, the bike should fire and keep running!If that fails ,i dont know what! thats the issue i had which sounds like yours,,, We two posted on here via a laptop, as we were stuck in baja , trying to revive my bike,and we got the stangest replys, like side stand sensor,call bmw( not an option there)Someone said it might be the chip in the key, try another,,, nope not it either,The bike does have a cut off from the pump,if on its side for a period,,, it was on its side,,but the day before, so the issue of the pump,was just an momentary issue,, i found out after i got home,a guy in great britan had made a jumper lead for that issue! BMW had a tech, issue on that problem i found out,,,but its not a recall! Go figure! Anyways hope this was some insight? Ride Safe
