Buying a BMW F650gs That Refuses to Run Right | Underrated Dual Sport? 

Check your idle actuator and clean it, check that throttle closes completely and has a little slack in the cable, check air temp sensor ( was the faulty part on my 650), loctide the battery connections, they come loose and cause similar problems and probably most important- stick to the propper starting procedure- turn ignition on and wait until one of the lights goes out ( dont know wich on on the dashboard, aprox. 5sec) then push the starter and always without turning the throttle, no gas at all! The ecu "resets" the throttle position when you turn on the ignition and gets faulty data if the throttle is not closed!

Bought 2001 model for $2500.00 Australian 6 months ago with rego I'm as happy as Larry with it done a service on it when i got home I think I've had my monies worth all ready .

Definitely think you got a good deal. I think you got a bad thing-a-ma-jig in the what's-it. Probably just need to add some Marvel Mystery Oil to the gas and the crank case, run it for a few miles, then change out the oil. LOL! Oh - FIRST!

Cracking bike these I have the Dakar version for over 7 years and been all over Europe Fork seals are a messy but easy enough job Just some advice the battery's on these have to be 100 % if not it causes all sorts of problems like not ticking over won't rev right so priorities this But if you get it fixed excellent buy I have just bought a new Tennere 700 but love the Dakar 650 that much I don't want to part with it

Great bikes. I had one and my wife has one. Her’s she’s ridden halfway around the world and back again. Only real issue is water pump impeller seals like to fail.

starting procedure as @KarsteinM. says. but hold that starter button for about 2 - 3 seconds after the engine starts ( the bendex gear, gets dis-engaged while the button is pushed in , so no grind ) its during this 2-3 seconds that the fuel injection computer ( ECU ) sets when injectors spray fuel into the cylinder , let the throttle alone . stick to this starting procedure , religiously . just a couple of times starting it and letting the button go as soon as it starts , and the bike will start stalling , no fun , especially on the highway and it just stalls at 65 mph , during heavy traffic , happened to me , in Los Angeles , on a 2009 g650 gs , to reset the TPS , turn off the ignition give it about 18 seconds then turn the key to on position ( don't start the bike ) then turn the key to off then repeat , then repeat one more time ( total 3) then twist the throttle fully open then fully close 2 -3 times , with the key in on position then turn the key to off position wait about 15 to 18 seconds and that resets the throttle , the other thing to keep in mind is if one stops for say gas , like a short ride , and the bike doesn't want to start , just give it 15 to twenty minutes to cool down, as the heat in the cylinder , will fight the piston , once it cools down then the piston isn't fighting against the pressure of the cylinder , and it will be able to reach the required rpm"s , for the fuel injection system to operate , its a thumper , there is ( on most of these bikes a decompression lever on the end of the exhaust cam that depresses a exhaust valve so that helps , lots of thumpers have that , leave it to BMW to come up with that starting procedure and that fuel injection system for a thumper , its actually Brilliant, but takes a bit used too .

I picked my '06 GS last week and it has developed the identical problem. I am leaning towards the fuel filter/regulator, your bikes PO mentioned this. To this end I have ordered a MANN-FILTER WK 692 which to all intents and purpose has the same spec. as the BMW filter/reg, about $20 vs $200 for the BM version. There is a video about it on the University of U-Tube.The MANN needs a tiny bit of Dremmel work and thats it. Over and out.

It's a rotax 650 pretty much the most reliable engine ever built won't be much that's wrong with it. Swm 650 as well another rare masterpiece of motor.

Did you find the problem? Mine had similar issues. Had a crack in the rubber intake boot. Also seems like she may need a new starter clutch.

This is a great channel if you like BMW motorcycles The video editing is very high-quality The audio is also very high-quality. It’s easy to understand everything that the people are saying. I’m wondering if you’re using an Insta360 or possibly a GoPro because I can see the fish eye lense

don't use the pen to poke around, the brain doesn't understand what they want from it. Just hold on.
