This guy deserves a bigger workshop and garage!!!
Yes, I think so too 😂 I’ve just finished building my new workshop, but it’s still too small…
Hi, I had this exact issue with the ambient air temperature sensor. Was stalling on start up. On motoscan app, the sensor was reading 95C. Disconnecting the sensor, the ECU doesn’t receive a signal and defaults to 10.5C, which is much better than 95C. Bike runs fine without sensor, until new sensor arrives. Thanks to your video, the air temp sensor was first thing I checked, so you saved me a lot of time. Thanks
Hey there. Thank you for your comment! Appreciate it!
Glad to hear the video was useful and your bike is running well again 🙂
Found these 2 videos very informative as I’m about to take delivery of a very low mileage 2001 model. Thanks for taking the time to explain everything I’ve learned a lot
Hey Nigel,
Thanks for your comment. Really appreciate it and glad it was useful.
Hope it all goes well with you new bike and you’ll have many happy miles on it 🙂
Fantastic Video series (Part 1 and Part 2). I learned so much about the F650GS's various systems, and some fault-finding techniques too! Thanks for taking the time to document this, I think it's going to help many people on a variety of problems. Plus your camera work and lightning is fantastic as well!
Thank you for your kind words! :) Glad it was helpful.
I know I have a lot to improve, but I’m working on it :)
Dear Sir, I live in Australia and I am just about to purchase a low mileage 2014 BMW G650G and I found your video very helpful and enlightening
As other have mentioned you deserve much more credit and subscribers
Thank you for your comment! Appreciate it! :)
I'm looking at one here in the USA, how's it treating you?
@@CharlieBam Good afternoon Sir, yes I did purchase that low mileage 2014 BMW G650GS and so far so good. I have already put some 3000 klms on the bike already
I have changed the standard exhaust pipe with a Dominator system from Poland, a new Lithium battery and a new rear tyre ( a Shinko 705 ) the first two items are purely to help reduce some weight off the bike ( I am no really interested in any additional exhaust noise )
I also changed the engine oil and oil filter and a new air filter , plus new front and rear brake pads and I am not disappointed that I bought this bike, its a keeper!
@alanreilly9056 thanks! Great feedback, think I'm gonna get it 👍
Hello. Thanks for this video, really helped me to fix the bike. Best regards!

Excellent video my friend, thank you 🙏🏾
Thanks for your comment! Glad it was helpful! :)
Good stuff, thanks for the video. Looking through your channel looks like you have good taste in bikes. 👍
Hey there. Thanks for your comment. You have a great channel as wel 😁 Keep it up!
you make the videos very easy to understand, you are very talented.
Thank you for your comment! :) I really appreciate it :)
Very didactic video, thanks. You deserve much more subscribers, keep up the good work!
Thank you for your kind comment sir! :)
@@garage_tales Hello! What does it mean when the idle control valve only cycles when turning ignition off?
Fantastic video, very informative. I have the same problem with my 2002 f 650 cs so theres lots to try. Thanks for the info ;)
Thank you for your comment. Glad you found it useful! :)
great videos thanks
Thank you for your kind comment. Glad it was helpful 🙂
Great video, straight forward, i have same probem with mine, will check out same this morning.
Hey there, thanks for the comment 🙂 Glad the video was helpful. Hope you’ll get it sorted! 🙂
You a hero! And I'm impressed. I jus got a 2001 !!!we'll see how it goes!
Hey there. Thanks for your comment! Glad the video was helpful and hope you’ll enjoy your new bike 🙂
I own a 2002 bmw f650gs. Some common problems I have had with it are like you mentioned. That bike being that old the fuel pump stuff goes bad. Like the rubber pieces in the fuel pump assembly. I rebuilt my fuel pump assembly with new rubber pieces that turned to gum, new fuel line, new aftermarket fuel pump. The engine runs good now.
Glad to hear you’ve got it sorted Darren! Enjoy the bike!
Thank you for your comment! :)
I couldn't find the rubber pieces separately. I had to buy an entire module $. Most of it was deteriorating anyway. The insulation on the wires for the pump and the low fuel level senor were completely falling apart also.
Excellent video, very useful, have subscribed. (But, I think you've got your Union Jack upside-down, which is a sign of distress!)
Hey there. Thank you for your comment. Glad the video helped.
Finally someone noticed the flag. Help!! 😂
Really informative. Thanks. I learned a lot about my bike's various systems. I wouldn't go quite that deep into it but would certainly check the simple things. Very nice style to presentation. Wish you would clean all that oil gunk off before re-assembly too.
Thanks for your comment! Glad it was helpful :)
Which oily gunk is that? :)
@@garage_tales The throttle boot and injector housing, you eventually got that off with replacement though. Laughed at the dry exposition then the crowd gasp at the launching idle plunger. You also skipped my nemesis of getting the @#$%! air box aligned and re-attached with those cheesy sheet metal screws into plastic. I won't ever understand the electrics and expected currents you measured but nice to know the modular components that can interfere with the idle, throttle response and lean/rich. Thx.
@@leefoote2586 Yep, put a new rubber manifold on it and cleaned the throttle body at the end :) Also gave the engine a bit of a clean before I took the rocker cover off to do the valve clearance (different video).
Glad you found something useful here :)

Thank you sir!
@@garage_tales And thank you. Great content. Please keep it coming!
Greetings squire. Thankyou for a fine video. Having start problems with my 650 gs 01. Fuelpump ok, has spark, cranks misfires and will not start. Thinking Hallsensor? Is it possible to chk that sensors function? Cheers from Sweden
Hi there. Thank you for your comment and sorry to hear you’re having bike trouble.
There is a part 1 to this video on my channel in case you find anything useful there, and also I have a video on testing the pick-up coil on a Triumph Adventurer. It would be pretty similar for your bike.
You can measure the sensor’s resistance (200-300 ohms). It’s gap is non adjustable if I remember correctly, but I think it should be 0.5-0.7 mm. best way would be to check it with a scope while cranking and see if you get a signal. If you would have an amp clamp for your scope you could measure the spark timing as well and see how it correlates with the crank position.
Happy to share more thoughts if you want to give me more details about what’s going on and what did you check so far :)
@@garage_tales Thank you for your input. Still no joy on the bike.
It all started with the fuelpump giving up right in the middle of nowhere so towed her back home. Changed fuelpump and filter/regulator. Gets fuel . Good fine spark on the plug, Cranks well but misfires and will not start. Thankful for any inputs. Cheers. Bike runs now. Thankyou.
@@saabsafir6095 Hi Saab. Sorry, not sure how I’ve missed this. Would have answered sooner. Hope you’ve fixed it by now and enjoy the cold rides, but just in case I’ll share a few thoughts. Curious to hear what it was :)
Have you removed the injector and see if it’s spraying correctly or perhaps it’s clogged? Have you checked the fuel pressure at the injector? Have you tried playing with the air and see if it’s getting too much or too little? Does it run better with slight throttle? And also have you checked the compression/valve clearance/valve timing? I realise they are all questions but maybe they’ll lead you to the problem :)
You said it was all fine before the fuel pump failed. New parts aren’t always good. I’d start with pulling the injector out and analyse the spray pattern, and also of you can, double check you pressure.
There is also an ecu reset procedure, but that did nothing for me. Might be worth a try though :)
Great set of videos! Where did you find your parts?
Cheers from the US!
Hi Lane. I’m from the uk and I used MotorWorks for these parts. I think they ship to US, but I’m sure you can find someone there. Beemerboneyard? Maxbmw?
In the US try this one as well.

Hiya, great video, i have same bike with eratic tickover, found that the air idle valve is loose and pops out of its plunger as yours does....can i ask you please...is that meant to happen do you know, i cant think its right. Not sure how the valve futs in the plunger? Cheers
Hi there. Thanks for your comment. Yes, if you cycle the key with the icv removed, it can pop out. It’s just a stepper motor without any feedback to the ecu. So it’s set up to unwind a set number of steps till it bottoms out in it’s bore and then just misses steps. And from that known position it backs up the right number of steps. So if it’s removed from the throttle body it will unwind itself completely 🙂
Thanks for explaining, i had thought it turns like worm gear, now i know. I called in bike shop in dorchester(run by tip top ex bmw techs)and they hooked the bike up to their computor and reset the
ecu, runs smooth handle bar vibes all gone, well worth getting done. Cheers
I just picked up one of these bikes, I’ve gone through almost everything that I’m capable of, it did run but barely. I drained fuel cleaned electrical contacts now it won’t start. Backfiring through intake. Is there a procedure to check crank sensor with ohm/volt meter
Hey there. Sorry for not being able to reply sooner. I hope you’ve fixed it by now? 🙂
I watched both 1 & 2 of these videos and they are very good. It is my understanding though, that the starter button should remain pressed for two seconds after engine start. Apparently this allows the computer to do some checks, but I notice that you don’t carry out this procedure. Is there a reason why?
Hi Joy. Thank you for your comment.
Yes, you are correct, it is recommended to hold the button down after it starts. There are 2 reasons why I didn’t.
1. It’s not my bine. If it was I’d probably have a habit of doing that without thinking about it.
2. I was just testing and trying to figure out what’s happening. I tried both holding it down and not, off camera, and there was no improvement or measurable difference in the way the bike runs in this case.
Hope that makes sense :)
Thanks again!
Vlad
I had never heard of this. I would think it's bad for the starter motor? or does the starter motor disengage after the engine fires up?
Very good video, but what exactly was the problem. The issue seemed to be the temperature sensor, or was it a combination of things? I am having a similar issue.
Hey Duncan,
It was a combination of the 2, but I believe the ICV had the bigger effect on the running.
Hope you get your bike sorted! :)
Thanks,
Vlad
I hear the word “assume” about the state of the O2 sensor and wonder: was there not a way to learn the proper resistance values? Or does BMW hide that info?
Hey there. Apologies for the late reply.
Bmw doesn’t make the sensors. There should be a data sheet from the manufacturer to specify what it should be, but it may bot be too easy to find.
It’s been a long time and can’t remember exactly, but I “assume” I was referring to the resistance of the O2 sensor heater. I didn’t want to spend a lot of time looking for what it should be.
Thanks for this information video. It helped me a lot, a have really struggled with my bike how have a similar problem...👍🏻🙏💪🏼😎
Hey Robert. Thanks for your comment and glad the video was useful 🙂
All the best!
Vlad
You never addressed the oil in the air box. What could cause that, and is it a problem?
Hey Adam. I’m pretty sure I mentioned about the oil level being to high. Cleaned the inside of the airbox a bit, set the level correctly, and a couple of months later when I did some more work on the bike the airbox seemed to be clean. You will get a bit of oily mist from the breather anyway. That’s normal. If you have actual oil in the box, there may be something wrong.
Hi brother! My front light doesn't works! Can you help me? Please
Hey there. Apologies for not being able to reply sooner. Did you check the fuse/relay or the light bulb itself?
Nice video. Thanks! I have some issue with my F650 CS (same throttle). Motorcycle stalls on idle. My ICV is not moving at all when I turn the ignition ON. When I turn it OFF it goes down and the a liitle bit up. Is it working correctly?
Thank you for your comment! :)
I couldn’t say for sure just from that, but it sounds like something may be wrong with it or the control side. Have you tried to block the port and see if it maintains idle?
@@garage_tales Thanks for reply. Yes I've blocked the port and the engine started to work smooth. I was also measuring DC current on ICV connector but I couldn't tell whether it's correct or not. I assume that the ICV is not closing and there is to much air. Nevertheles I've found some used ICV and ordered it. See what's happened.
@@matl179 Sounds like there’s your problem then :) Measuring the voltage will only tell you if it’s getting commanded to move and only on one coil at a time. It’s will be a switching voltage I presume, so you will need a scope to actually see what’s happening, and measure both coils at the same time. Using a multimeter, it probably just have you an average voltage :)
Hope the used one is good and solves your problem :). Silly question, but do you know the starting procedure on these singles?
@@garage_tales Good tip on measuring voltage. I was using standard multimeter and had 10,8V on ignition ON and 11,8V after a second when I turned it OFF. Just wondering if tje voltage is to low (maybe it's the battery issue - I need to check my battery again). As for starting procedure I know that I have to hold ignition couple of seconds after starting the bike. Do you know if there is some other throttle adapting procedure?
@@matl179 No. that’s it. I think twisting the throttle all the way up 3 times with the ignition on, engine off is said to reset the ecu, but made no difference for me.
I love my 2002 BMW F650gs,,, I guess after a new spark plug, fresh oil and filter, new airfilter and completely checking all valves and finding both intakes way too small of a gap at 0.01 I was expecting the popping sound to go away thru the intake when I give her some gas..I cannot think of any other thing that can cause this crazy sound?? Are all these Rotax 650 this noisey?? the bike has just under 13k miles
Having the valves too tight will burn them. Hope yours aren’t too damaged. But no, they’re not particularly noisy. What sort of popping sound are you hearing? Is it a backfire?
@@garage_tales no backfire, bike runs strong as hell just loud popping sounds from intake when I get on it
if I feather the throttle, i dont hear it as muchhappens just above 3500 rpm
@@garage_tales intake were at .01 when I checked, then I got the correct shims and the final clearannce was .09 and .10 plenty of space
My bike does this with an Akropovich silencer but not with the OEM silencer🕊
👍👍👍👍👍🤗🤗🤗🤗🤗............
Thank you!
Hi there, what build year is this GS 650?
Hello. It was registered in March 2000.
so next time, just get a can reader and find out that the temperature read out is totally wrong?
Would have used it if I had one 😁 You can see at the beginning of part 1.
