If you want to improve reliability changing the rectifier/regulator for a CompuFire 55402 or 55403 will help a lot as it's a SERIES unit which unloads the stator, unlike the standard shunt type which keeps it fully loaded at all times.
Thanks! Yes, the I'm aware of the not-really-up-to-scratch-rectifier/regulator. When time comes we will most certainly change the regulator/rectifier too. Electrickery is kind of important on these bikes, so anything that we can do to improve reliability is a good thing. Thanks!
Yes, sort of. If there is a proven and readily available better option, I’ll install that. However at the moment I’ve not had any reason, nor have I done any research. In other words, I’m ignorant about the alternatives, but I know the standard system isn’t the best. I hope that makes sense.
My F800ST stator literally failed on the way back from the Dealer where I had just bought the parts to fix it. I was on the side of the road under a bridge and with a few tools I had with me I was able to replace the stator. I even used an old can I found to strip the wires. I professionally installed it when I got home but my roadside repair got me the last leg of the trip home.
Love your channel! I am looking at a 2009 this weekend. The f800 is my dream bike and these videos are helping me make an informed decision! Thank you!
Hi! I'm glad you've found the channel useful. I hope you get your bike soon and that you now know how to take good care of it. Feel free to ask any questions if you have any and I'll try to help! Thanks again!
Used your video to reference a change out my stator on the 2010 F800GS yesterday. Good to see someone else struggled with the plugs up top and that last little hidden cable tie. Installed the Electrosport unit also. Was told by the BMW dealer (who wanted to charge me $1800 CDN to replace the flywheel and stator but did not give any guarantee that would work to make the staro last) that the aftermarket stators were only lasting 15-20,000 km. I think the biggest issue with stator heat is caused by the closeness of the exhaust to the stator housing. Perhaps this is why you see people who do a lot of highway riding as opposed to around town with stators that seem to last longer. They are not affected by the upstream of the convective heat from the exhaust. I will wrap the exhaust in heat wrap in that vicinity and see if that helps. $200 for the aftermarket stator and gasket and a couple hours, I can change the thing every year and be money ahead of the $1800 BMW fix.
That's good to hear. I like it when people tell me that they've used a video to save some money. Please keep me posted on how heat-wrapping the exhaust fares and how the bike runs in general. Thanks for watchin' and hope you stick around! Cheers!
@@sander.buitenhuis Actually I changed it as I was wanting to sell the bike. I had a bad hip so could no longer lift my leg to get on it. As far as i know the fellow who bought it is still running it, but not sure how many km he puts on her year.
Thanks a lot for sharing these GREAT videos. Very useful. I have a 2009 F650GS twin and in a near future, I will try to start making some little maintenance tasks.
Thanks! I'm glad that they're useful. I hope more people would dip into doing their own maintenance, so I wish you all the best with that. I'm sure it'll go well and that you'll like it and save some money too. :)

My BMW F800S's battery does not seem to be charging, so I'm assuming it's the stator. Thanks for the video, doesn't seem to complicated - I'll attempt to do the same on my motorcycle in the new season.
Sorry to hear about the troubles on your bike. There are procedures of checking the stator and the regulator/rectifier. I’m sure they are in the BMW workshop manual and/or the Haynes manual or you can find them on the Internet. It would be a waste to change the stator only to find out that it was the regulator. A bad battery can also wreak havoc on these modern ECU powered motorbikes, so I’d double check that too. I hope you’ll be back on the road soon! Apologies for the late reply!
@@JockeSelin Thank you. I'll be checking where exactly the issue is, for now the motorcycle is in storage until spring. The battery is only a year old, and I've changed it with a new battery from a friend for a few rides - still the same result.
Excelent video, as all others are! I saw auto oiler for the chain on your f800gs...could you make another video how to connect, where to place the reservoir and the most important thing, where is the best place for the oiler tip-where is the best place to lube the chain on the f800gs and how to attach so that the chain is not damaging the oiler tip
Thanks! The chain oiler is a Scottoiler which is specifically adapted for the BMW F800GS. It was fitted to my bike, and we did fit one to Caz's bike as she bought one 2nd hand off eBay. The fitting instructions are very good and it'll answer all your questions on where to install it (it only goes in one place) and how to position the lubing nib onto the rear sprocket. Have a look here: kbvps.scottoiler.com/article/f650-700-800gs-2008-2016.html In the beginning you could only buy this kit through BMW dealers, but it looks like it can be bought through other retailers now. www.motorworks.co.uk/vlive/Shop/Parts.php?T=4&NU=15&M=90&Ct=GP Personally I do not rate the system very much. I see it as a prolonging-system rather than a total lubrication system. I carry an eye-drops-bottle with regular engine oil with me and I "adjust" the amount of oil used by putting a few drops onto the chain using that rather than altering the Scottoiler settings. I find adjusting the settings very difficult, it's rarely the amount of oil you need, but either too little or way too much. It also makes it difficult when travelling as you need to carry extra Scottoiler branded oil. However, once set to a "regular" interval, it'll keep dripping a bit onto the chain, enough to not have to worry about the lubrication during the day. If I go off-roading or riding in the rain, I keep dripping some extra oil from the eye-drops-bottle to keep the lubrication at the correct level. I doubt I'll be making a video about the Scottoiler, as I don't really "feel for it", however, if there's enough requests, I might make a talking-video about it. I hope this answers some of your questions. 😎👍🏻 Thanks for watchin'!
Hey Jocke, great video as usual! The manual is not saying anything about flushing the oil and neither you in this video. So I guess no oil on this side? What's the lubrification for the wheels there?
Hi, the stator-side is not bathing in oil. However, there was a bit of oil inside there. I don't know if it is residual oil that has just seeped through the seal over time, or something more deliberate. In short; you do not need to drain the oil from the engine to open up the stator cover. I hope that's what you needed to know. Thanks for watching! 😎👍🏻
I knew it's goog idea to read coments below. Some People of mine told me that stator is in the oil and I really wasn't sure if it's real info and you just skipped the oil draining. Thank you very much for your videos!. I really love if I'm able to repare my bikes myself. Everything you do is really helpfull! 🙂
Hey! I don’t really know how to answer this. Ummm… so, ummmm, in the workshop manuals, I think there’s a way to test the stator, but I’m not 100% sure as I’ve never had to do it. I know the rectifier can break, but it’s a far less common issue. If you don’t mind spending the money, then putting in a new stator is a good investment for reliability. Hope it works out!
@@Joksa999 Checking the plugs is cheap but tedious - the air box is not simple to take off. However, I would get the stator first, and if it still is not fixed, then the regulator. Also, try searching for the BMW workshop manual and/or buy the Haynes Manual, it might explain how to test the stator and/or the regulator/rectifier. Good luck!
@@JockeSelin i checked the strator cable it was a pain to get the plug Out and Check it If i checked it correctly its either the strator or the plug but the Plug Looks good in my opinion im gonna give a Update in a week or so
The grease is just there to keep the gasket from falling down. You can do it whichever way you want as long as the gasket is in the correct place. Some use a bit of tape, and put one part of the cover on and then pull the tape out. Grease is easy and gives you time.
I have f800 gs and I dont know how to care water pump and the tools around them. My water pump is sliding a little water to outside. I couldn't find any video about it in your videos. Thanks.
Hi, thanks for watching. Unfortunately I have not made a video about the water pump. I know it can become a problem, but none of the bikes I have worked on has had an issue. I can only hope you find that information in a forum or a manual. Sorry I can’t help more. 😞
I’m glad you found it helpful ☺️The general consensus seems to be that the windings are a bit thin for how hot it gets. The later models have additional holes in the flywheel to help with cooling.
@@SamuelvandenBrink-le8gq I don't know from the top of my head, but I think it might have been changed in 2013, and I'm pretty certain that your 2016 bike has got it. If you search for F800GS flywheel, you'll see some pics without holes, and some with holes in the flywheel.
@@JockeSelin Well, turned out to be a burned coil anyways. Even with a 2016 model. Oh well... feces occur, as you English speaking people tend to say. It has been fixed with a refurbished one, saving me a lot of money, but with a two-year warranty. Thanks for the video. I did put me in the right direction.
Glad to hear you found the problem. How did you diagnose it? Did you use a diagnostics tool like the GS-911 or something else. My car’s diagnostics tells me if there’s a misfire on a cylinder, so it’s easy to spot and fix. Glad it is all working though! 🤟🏻😎👍🏻
My 2008 f800gs battery is not charging. I bought a new battery yesterday but the tough starting seems to go on. Meanwhile the old battery seem to charge OK with a overnight charger. Could this be a stator problem? Cheers 🇵🇹🇮🇲
Sorry to hear you’re having issues. It’s probably the stator or the rectifier. Off the top of my head I don’t remember how to check which one it is. However the stator failures are waaaay more common than the rectifier failures. The stator seems to fail around the 30k miles / 50k km range, so if that is sort of your mileage, I’d put my bet on that your stator is fried. If you can put a multimeter on the battery when it’s running, you might get an indication of what is wrong. Where in Portugal are you located! Obrigado por assistir e boa sorte! 😎👍🏻
@@JockeSelin thank you. I'm in Cascais and my local mechanic will take a look at it on Wednesday. I'm not qualified enough or stuck on the side of the road so instead of getting my hands on it, I'll pass it on to someone who knows what they are doing haha Thanks for the tips ✌️
I’m sure they can help you, but just in case, do you have an IG account or similar where I can send you a message or email? My email is jocke@selincite.com.
Sorry for the later reply. I don't recall what the odometer reading was at the time of change, and I can't remember what it's now either without going out to check, but the bike is still working fine. Sorry I can't be of more help.
Hi! I´ve been waiting on a good radiator fluid change video for an F800GS, and the rumor goes that you do really good videos on these BMW´s, do you think you´ll do one for all of us in dire need of help? Thanks mate, and blessings from Texas.
Thanks, Ian! Thanks for watching too. Coolant change is on the to-do list, I think my bike might need some new this winter. If you can't wait and want to give it a go, there's only one little trick to it and that's the bleed screw on the water pump. There's an arrow at it, not totally obvious but it's there. You need to heat the engine in cycles and let trapped air out from that bleed screw. To aid the trapped air to the pump you can tilt the bike from side to side and squeeze the hoses (watch out they're hot!). Three or four cycles should do it. You'll know when there's no air bubbles coming out from behind the bolt-head when you open it carefully. Video is coming, so if you can wait, there'll be one, just don't know when. Thanks again!
Later models have a ventilated flywheel (and maybe other components), I believe it came with the facelift model, which I think is 2013. I believe this change was a huge improvement, but whether it solved the issue completely, I don’t know.
Hi, the usual symptoms of a bad stator are under charging - which can easily be confused with a bad battery. As the stator gets worse, it will no longer be able to generate enough charge to keep the bike electrical systems functioning - so you may start to see strange behaviour (heated grips not functioning) as the ECU tries to keep the bike running. Constant stalling and dying of the bike sounds more like it may be fuel pump or fuel filter related.
I had a bit of oil in there too, and my old stator looked a bit barbecued, even if it worked. I don't think it's anything to worry about. Just clean it up and put it all back.
Hi. Can You tell me if in my ATV the stator mayby the problem why the ventialtor on radiator dont turn on when the temprature go high ? Or the speedometr blink rest and sometimes dont show anything.. ? My atv is AEON600 2018.. please give me a feedback..
If you have an F800GS, which I don't know whether you do. You need to plug in a diagnostics device such as GS-911 and from there you can activate the radiator fan (if that's your issue, which I don't know again). If it doesn't activate, maybe take it off and see whether it's seized or something. The GS-911 would also show you any fault codes. On a modern bike it's really difficult to guess the problem unless you have a diagnostic device. The stator provides power to the rectifier which controls it so that the bike gets 12V (or around 13.8V actually). Your battery might be fine, but if the stator doesn't provide the power, or the rectifier doesn't clean it, the battery doesn't help.
How much should be the AC voltge when the bike is in slow motion? 20-25 it's fine or too low? My motorbike is giving to me 20-25 when i'm not accelerating, and 50v at 3000rpm. It's OK?
I don't know, and I haven't looked in the Haynes manual, but I don't think it's written in there. I think your best bet is to search and ask on forums or F800GS groups. Or hope someone who reads your question here has an answer. Good luck!
I replaced mine as a precaution around 30,000 miles / 50,000km - and it's worked fine since then. I can't recall hearing of someone having to replace it multiple times. So if anyone reading this, has replaced the stator, please chime in with your mileage / kms, and let us know if you've had more than one stator failure.
Apparently the only information I was looking for was withheld purposely about which torque I need. I don't blame you, but my believe is that every owner should have the right to repair his own motorbike and the manufacturer should not try to withhold tools or information needed to do so. This just creates an unfair dependence on the manufacturer or people repairing it with the wrong Nm and breaking down because of it.
Hey my man. I just bought a '08 F650GS, it's the same engine and frame. It came dismantled because the engine was broken. I purchased a new one and just put it back in place. Everything going well till now. There's 5 connectors in the same chord as the spark plug coils. 2 of them go to the injectors, the other 2 go to the sensors on the engine block. But what about the 5th one?! Does yours have a spare connector on the part?! I can't find anywhere to plug it..
I can't give you a definitive answer, but my friend's F800GS has a wire sticking out just behind the cylinder heads and there's nothing connected to it. Without the wiring diagram, pictures, etc, and time, it's impossible to provide any more information. I'd suggest posting some pics and your query on some F650GS(twin)/F800GS forum, as people with similar year and model might be able to help more. Good luck!
So no disrespect to this effort at all but the idea that stator " just dies" is less helpful than explaining why it dies and how an aftermarket stator fixes the cause of premature OEM stator fails. Wire breaks? poor connections? Wire gauge issue? Have we looked at OEM stator to determine what is cause of failure? Stators are not wear items, just a big coil of wire. On Ducatis failures were usually at connections. Ages ago was on first name basis with NA Sales Manager for Electrex re Ducati electrical problems from stator/rotor to reg/rectifier. So far not on my F800GS but very interesting subject. thanks.
Hi Rich, there's a few reasons why I didn't go into the "why's" in the video, but your question is valid. If you search on the Internet, there's a plethora of Internet Experts(tm) 😉 who all know best as to why the stator fails. My layman's understanding is that the stator itself fails due to having (slightly?) too thin wires in combination with a fairly basic shunt-rectifier that sort of abuses the output of the stator and thus causes the stator to run unnecessarily hot. Apparently BMW have released a ventilated flywheel to combat this issue!? Neil John above also recommends changing the regulator/rectifier (which we'll do in due course) for a more advanced one. However, whether this is the technically correct diagnosis I'm not sure - which is one of the reasons that I've not gone into the diagnosis. Feel free to search the Internet and draw your own conclusion - there's a lot of information on AdvRider forums for example. What I do know for certain is that they do die and they will leave you stranded (once the battery is depleted). A very close friend of mine with more miles on his F800GS had this happen to him and he changed to the same brand aftermarket stator and his bike has been running well since. The new, aftermarket, stator is supposedly manufactured with a bit higher components so it should last better - whether this is the case we'll not know for a while. I hope this clears things up a bit, and sheds some light on why I'm a bit reluctant to add to the Internet Expert's Panel 🤣
Very typical at many bikes i used to ride on. Usually stator "dies" as a consquence, not a cause. Heat in semiconductor rectifiers are the main reason, as they are based on very old technology. Transistors are being overheated in two ways: current and also frequency and start making shortcuts in higher temperatures. Happened at my bikes (DL650, Tiger 955i) every 6-8 years, untill rectifier was beind replaced by accesory one, based on newer MOSFET transistors (fast switching, heating less). It was some years ago, I ordered MOSFET units from US i quite a reasonable price, AFAIK ~100 USD plus bike socket adaptor (no cutting, clean job) and delivery.
Hi Ivan, I don't have a workshop manual for the BMW F800GS except for the Haynes manual, and I need that one for servicing our bikes. I'm sure you can buy one yourself. The Haynes manual is pretty good actually. haynes.com/en-gb/bmw/f800gs/2008-2016 (no affiliation)
I have explained this in several videos, and I'm very tired at the moment, so apologies if my answer is a bit short and to the point. First is that I don't provide a free manual, just entertaining how-I-do-it videos. Buy the manual. Second is that there might be differences between my bike and your bike. We have two F800GS' and there's a lot of differences between them. Thirdly, I don't want to be blamed and sued if you follow incorrect advice given by me. See the first point. 🤪 So, get a manual that's for your bike. Use it. I'm also pleased no Honda guys are going to watch my videos, I'm sure all my videos would feel dirty and wanting to have a shower. 🤪 Thanks for watching! 😎👍🏻👍🏻

@@JockeSelin i checked the strator cable it was a pain to get the plug Out and Check it If i checked it correctly its either the strator or the plug but the Plug Looks good in my opinion im gonna give a Update in a week or so
Fingers crossed for you! 🤞🏻🙂🤞🏻
13:10 the gasket should hold in by the screws on the cover & applied both in one time so would be avoid using grease other than that 👍.
The grease is just there to keep the gasket from falling down. You can do it whichever way you want as long as the gasket is in the correct place. Some use a bit of tape, and put one part of the cover on and then pull the tape out. Grease is easy and gives you time.
I have f800 gs and I dont know how to care water pump and the tools around them. My water pump is sliding a little water to outside. I couldn't find any video about it in your videos. Thanks.
Hi, thanks for watching. Unfortunately I have not made a video about the water pump. I know it can become a problem, but none of the bikes I have worked on has had an issue.
I can only hope you find that information in a forum or a manual. Sorry I can’t help more. 😞
Hi, Thanks for sharing, Really helpful video. But why does the stator break down in the first place? It is a non-moving part, isn't it?
I’m glad you found it helpful ☺️The general consensus seems to be that the windings are a bit thin for how hot it gets. The later models have additional holes in the flywheel to help with cooling.
@@JockeSelin what dear dit the later models come out? Mine is from 2016.
@@SamuelvandenBrink-le8gq I don't know from the top of my head, but I think it might have been changed in 2013, and I'm pretty certain that your 2016 bike has got it. If you search for F800GS flywheel, you'll see some pics without holes, and some with holes in the flywheel.
@@JockeSelin Well, turned out to be a burned coil anyways. Even with a 2016 model. Oh well... feces occur, as you English speaking people tend to say. It has been fixed with a refurbished one, saving me a lot of money, but with a two-year warranty.
Thanks for the video. I did put me in the right direction.
Glad to hear you found the problem. How did you diagnose it? Did you use a diagnostics tool like the GS-911 or something else.
My car’s diagnostics tells me if there’s a misfire on a cylinder, so it’s easy to spot and fix.
Glad it is all working though! 🤟🏻😎👍🏻
Oil started gushing out of my stator cover when I started the bike. Why would that be? Torqued the cover to spec. Used a gasket. Thanks
I’m sorry to say that I have no idea. Try asking in forums and such if you haven’t already.
I hope you get it sorted, good luck!
Great video!! Well done! One question: how is the ElectroSport stator? Did you have any issues in terms of durability? Thanks again for your sharing!
Thanks, Davide! I think it's a bit too early to comment on durability, however, both our bikes are working fine. Thanks again! 😎👍🏻
@@JockeSelin how about now?
Still running well, but they haven’t been ridden much due to that C-thing that happened. All good though. 😎👍🏻
Thanks for sharing!
My 2008 f800gs battery is not charging. I bought a new battery yesterday but the tough starting seems to go on. Meanwhile the old battery seem to charge OK with a overnight charger. Could this be a stator problem? Cheers 🇵🇹🇮🇲
Sorry to hear you’re having issues. It’s probably the stator or the rectifier.
Off the top of my head I don’t remember how to check which one it is. However the stator failures are waaaay more common than the rectifier failures.
The stator seems to fail around the 30k miles / 50k km range, so if that is sort of your mileage, I’d put my bet on that your stator is fried.
If you can put a multimeter on the battery when it’s running, you might get an indication of what is wrong.
Where in Portugal are you located!
Obrigado por assistir e boa sorte! 😎👍🏻
@@JockeSelin thank you. I'm in Cascais and my local mechanic will take a look at it on Wednesday. I'm not qualified enough or stuck on the side of the road so instead of getting my hands on it, I'll pass it on to someone who knows what they are doing haha Thanks for the tips ✌️
I’m sure they can help you, but just in case, do you have an IG account or similar where I can send you a message or email? My email is jocke@selincite.com.
😁👍👍 GOOD~!!
Thank you! 😊👍🏻
How many kilometers has the Electrosport stator lasted on you?
Is it still working?
Sorry for the later reply.
I don't recall what the odometer reading was at the time of change, and I can't remember what it's now either without going out to check, but the bike is still working fine. Sorry I can't be of more help.
Hi! I´ve been waiting on a good radiator fluid change video for an F800GS, and the rumor goes that you do really good videos on these BMW´s, do you think you´ll do one for all of us in dire need of help? Thanks mate, and blessings from Texas.
Thanks, Ian! Thanks for watching too. Coolant change is on the to-do list, I think my bike might need some new this winter.
If you can't wait and want to give it a go, there's only one little trick to it and that's the bleed screw on the water pump. There's an arrow at it, not totally obvious but it's there. You need to heat the engine in cycles and let trapped air out from that bleed screw. To aid the trapped air to the pump you can tilt the bike from side to side and squeeze the hoses (watch out they're hot!). Three or four cycles should do it. You'll know when there's no air bubbles coming out from behind the bolt-head when you open it carefully.
Video is coming, so if you can wait, there'll be one, just don't know when. Thanks again!
I heard that models from 2013 dont have this issue enymore, is it correct?
Later models have a ventilated flywheel (and maybe other components), I believe it came with the facelift model, which I think is 2013. I believe this change was a huge improvement, but whether it solved the issue completely, I don’t know.
What are the symptoms of a bad stator? Constant stalling and dying of bike?
Hi, the usual symptoms of a bad stator are under charging - which can easily be confused with a bad battery. As the stator gets worse, it will no longer be able to generate enough charge to keep the bike electrical systems functioning - so you may start to see strange behaviour (heated grips not functioning) as the ECU tries to keep the bike running.
Constant stalling and dying of the bike sounds more like it may be fuel pump or fuel filter related.
good background music
Thanks!
Inside my cover was quite a bit of oil, and the stator looks really crudy. What do you make of it? I assume there isn't supposed to be any oil?
I had a bit of oil in there too, and my old stator looked a bit barbecued, even if it worked. I don't think it's anything to worry about. Just clean it up and put it all back.
Hi. Can You tell me if in my ATV the stator mayby the problem why the ventialtor on radiator dont turn on when the temprature go high ? Or the speedometr blink rest and sometimes dont show anything.. ? My atv is AEON600 2018.. please give me a feedback..
What's an ATV? A quad? I'd start with a multimeter to see the charge voltage, etc, then plug in the diagnostics tool. 🤷🏼♂️ Good luck!
@@JockeSelin the battery is new.. charge voltage should be ok :(
If you have an F800GS, which I don't know whether you do. You need to plug in a diagnostics device such as GS-911 and from there you can activate the radiator fan (if that's your issue, which I don't know again). If it doesn't activate, maybe take it off and see whether it's seized or something. The GS-911 would also show you any fault codes.
On a modern bike it's really difficult to guess the problem unless you have a diagnostic device.
The stator provides power to the rectifier which controls it so that the bike gets 12V (or around 13.8V actually). Your battery might be fine, but if the stator doesn't provide the power, or the rectifier doesn't clean it, the battery doesn't help.
How much should be the AC voltge when the bike is in slow motion? 20-25 it's fine or too low? My motorbike is giving to me 20-25 when i'm not accelerating, and 50v at 3000rpm. It's OK?
I don't know, and I haven't looked in the Haynes manual, but I don't think it's written in there. I think your best bet is to search and ask on forums or F800GS groups. Or hope someone who reads your question here has an answer. Good luck!
The oil must be drained?
No, it doesn’t need to be drained. You can just remove the stator cover.
How ofen do you need to reapleace the stator?
I replaced mine as a precaution around 30,000 miles / 50,000km - and it's worked fine since then. I can't recall hearing of someone having to replace it multiple times. So if anyone reading this, has replaced the stator, please chime in with your mileage / kms, and let us know if you've had more than one stator failure.
Just changed my first one at 60000 miles, mostly motorway use.
@@JockeSelin Mine runs 55000km and I hawe poor voltages and battery is empty. Hig rpm it still give some voltage. Work on it now...
@@Makedonialainen Hope you get it fixed and are back on the road and trails soon! 🤞🏻😎🤞🏻
Apparently the only information I was looking for was withheld purposely about which torque I need. I don't blame you, but my believe is that every owner should have the right to repair his own motorbike and the manufacturer should not try to withhold tools or information needed to do so. This just creates an unfair dependence on the manufacturer or people repairing it with the wrong Nm and breaking down because of it.
Hey my man.
I just bought a '08 F650GS, it's the same engine and frame. It came dismantled because the engine was broken. I purchased a new one and just put it back in place. Everything going well till now. There's 5 connectors in the same chord as the spark plug coils. 2 of them go to the injectors, the other 2 go to the sensors on the engine block. But what about the 5th one?! Does yours have a spare connector on the part?! I can't find anywhere to plug it..
I can't give you a definitive answer, but my friend's F800GS has a wire sticking out just behind the cylinder heads and there's nothing connected to it. Without the wiring diagram, pictures, etc, and time, it's impossible to provide any more information.
I'd suggest posting some pics and your query on some F650GS(twin)/F800GS forum, as people with similar year and model might be able to help more.
Good luck!
So no disrespect to this effort at all but the idea that stator " just dies" is less helpful than explaining why it dies and how an aftermarket stator fixes the cause of premature OEM stator fails. Wire breaks? poor connections? Wire gauge issue? Have we looked at OEM stator to determine what is cause of failure? Stators are not wear items, just a big coil of wire. On Ducatis failures were usually at connections. Ages ago was on first name basis with NA Sales Manager for Electrex re Ducati electrical problems from stator/rotor to reg/rectifier. So far not on my F800GS but very interesting subject. thanks.
Hi Rich, there's a few reasons why I didn't go into the "why's" in the video, but your question is valid. If you search on the Internet, there's a plethora of Internet Experts(tm) 😉 who all know best as to why the stator fails. My layman's understanding is that the stator itself fails due to having (slightly?) too thin wires in combination with a fairly basic shunt-rectifier that sort of abuses the output of the stator and thus causes the stator to run unnecessarily hot. Apparently BMW have released a ventilated flywheel to combat this issue!? Neil John above also recommends changing the regulator/rectifier (which we'll do in due course) for a more advanced one.
However, whether this is the technically correct diagnosis I'm not sure - which is one of the reasons that I've not gone into the diagnosis. Feel free to search the Internet and draw your own conclusion - there's a lot of information on AdvRider forums for example.
What I do know for certain is that they do die and they will leave you stranded (once the battery is depleted). A very close friend of mine with more miles on his F800GS had this happen to him and he changed to the same brand aftermarket stator and his bike has been running well since.
The new, aftermarket, stator is supposedly manufactured with a bit higher components so it should last better - whether this is the case we'll not know for a while.
I hope this clears things up a bit, and sheds some light on why I'm a bit reluctant to add to the Internet Expert's Panel 🤣
Very typical at many bikes i used to ride on. Usually stator "dies" as a consquence, not a cause. Heat in semiconductor rectifiers are the main reason, as they are based on very old technology. Transistors are being overheated in two ways: current and also frequency and start making shortcuts in higher temperatures. Happened at my bikes (DL650, Tiger 955i) every 6-8 years, untill rectifier was beind replaced by accesory one, based on newer MOSFET transistors (fast switching, heating less). It was some years ago, I ordered MOSFET units from US i quite a reasonable price, AFAIK ~100 USD plus bike socket adaptor (no cutting, clean job) and delivery.
Yabba Dabba do you
Hi jocke.
Help me please
I need manual shop of BMW f 800
Can you do it for me la very important because i can't repair mi bike
Thanks a lot
Dear frend
Hi Ivan, I don't have a workshop manual for the BMW F800GS except for the Haynes manual, and I need that one for servicing our bikes. I'm sure you can buy one yourself. The Haynes manual is pretty good actually. haynes.com/en-gb/bmw/f800gs/2008-2016 (no affiliation)
you could say the tork number G! Honda guy is not going to see this video
I have explained this in several videos, and I'm very tired at the moment, so apologies if my answer is a bit short and to the point.
First is that I don't provide a free manual, just entertaining how-I-do-it videos. Buy the manual. Second is that there might be differences between my bike and your bike. We have two F800GS' and there's a lot of differences between them. Thirdly, I don't want to be blamed and sued if you follow incorrect advice given by me. See the first point. 🤪
So, get a manual that's for your bike. Use it.
I'm also pleased no Honda guys are going to watch my videos, I'm sure all my videos would feel dirty and wanting to have a shower. 🤪
Thanks for watching! 😎👍🏻👍🏻
