John Wilkinson, Thank you for your comment John, much appreciated. I really didn’t know whether to post the video or not as it doesn’t fill you with joy🤦🏼♂️. However at the end of the day it was nothing anyone could have done and no one was hurt. Jason is an excellent rider. If he was some crazy speed freak constantly over revving his bike then that could have been different. When this happens the first thing we all do is type it into Google and yes you do find others have experienced this, but I cannot find a video of the end result.
@@normski3091 The video is very well put together, under those circumstances I'd be shaking like Chubby Checker, I have the same motorcycle in Spain (mine is 2007) now I'm scared, it has some 35.000 km but I understand that it can happen anytime. Please let us know what will be your next step. I'm glad that the kid walked in one piece.
Never seen something like that. Great video. The important thing is your son is safe, when something like that occurs while you are riding...you never knows what it could happen.
Davide Bugni Hi Davide, thank you for your comment and that is 100% true. At the end of the day it is a 15 year old bike that Jason has had for about 3 years. We have really enjoyed looking after it has now not going to go anywhere, unless we replace the engine. 🤔
I do think it is a very rare failure Davide. But what can you do, apart from having your cylinder head completely rebuilt by specialist engineers! If you see the cost of just the BMW valves alone you will just keep riding as we all do.
@@normski3091 it is probably cheaper to find a new engine, rather than repair valves, cylinders, etc. Of this one. Ah...by the way I have just replaced the drive shaft of my bike, the rubber torsional shock absorber was gone. Thanks for your videos.
Hi, First of all. Your a Great Dad to work on the Bike for your Son. Second, your a Great Mechanic. It’s too bad the Piston has a Hole in it. You could have just replaced the Cylinder, Head and Piston, along with the New Valves and everything. At least the GS has been around long enough to where you can find a Good Engine for a Decent Price. You’re going to have a big Job ahead of you, but at least you are a Great Mechanic. If anyone can handle the Job, I think you could. Thanks for making these Videos. I ride a 2006 R1200GS and have really learned a lot from you. I’m glad your Son is Safe. It could have gone really bad if the Engine had locked up. He had a Angel Riding with him.👍❤️
Wow what a disaster . I have the same 15 year-old bike right down to the colour and have used you videos to service,change the alternator belt and re-grease the shaft drive, this is one video I'm hoping not to need . I am however looking forward to seeing part two. Chin up- upwards and onwards.
A little late but just seen this..., slightly scary! I have the same model and was wondering if a previous owner had been in there before? The head date looks like a 06? Regardless, pleased no one injured. Nice work sorting this out and great footage of complete teardown and rebuild.
Hi Stefan, yes it was such a shock. Jason rang his wife first as his mobile had run out of charge, she rang me and said he had broken down and there was ‘smoke’. We jumped in his van, it was a beautiful summer evening and when we arrived the bike looked perfect🤔. As we drove back with the GS in the back and Jason described what had happened I thought ‘why have I never heard of this happening before’ 😩. Frightening eh😱
@@normski3091 Thank for the reply. BTW....the foam insert behind the front cover was standard but essentially acted like a sponge and accelerated the corrosion of the front cover, hence most people threw them away. Best ``Stefan
Yes i would look into the cost and availability of a second hand engine .May get you on the road faster and cheaper . And since its a daily driver, faster repair could be important. I would however continue with the teardown of this motor and keep your options open. Best of luck
The effort involved , and possible costs , in a total engine rebuild is vert likely to be more than just fitting a second hand engine . The only good news is it did not lock up and the throw the rider down the road.
Absolutely Keith, imagine how bad it would have been if Jason had be thrown off at 70mph on a fast, busy A38 dual carriageway 😱. Think as a family that reality has calmed us down about the state of the bike🤗. I will either have a project for a long time (found a 2005 engine with just 33,000 miles for £699) or throw the bike away. Watch this space🤔
Certainly did Tanguy, but it seems a long time ago now. Just leaving for a week through the Highlands of Scotland on my new 1250GS Triple Black without a thought in the world of rebuilding another bike🤣
Always thought BMW bikes were the most reliable but for the valve to drop its bad form, it moved me to look at reliability tables and BMW bikes, like their cars, are very mediocre (and drive both a BMW car and bike), with regards to reliability the Japanese have it licked, I’ve bought new BMW bikes only to find frame and cylinder rusting, to be fair BMW fixed immediately but I’d rather not have had the problems in the first place. Right getting my RT out and going for a ride, hope I make it back without the piston falling out, but as the great Normski services my bike I’m sure it won’t!
Do you think it is possible to swap cylinder heads from the newer model ? The one that is used in the 2011 models and ninet’s? I assume that model has improved valves Assuming no cost issues or a good salvage pair is available...
Hi Carlos I don’t think that is possible. I am not 100% sure but the model change in 2007 and then again 2010 and BMW do make numerous changes, even any gaskets are different. Positive way would be just to call a BMW dealer and ask their service, if any are open in these difficult times🤦🏼♂️
Very interesting video, thank you sir! After an adventure on a rented 1250, I want to leave my F650 behind and buy a real GS. After a lot of research into affordability, horsepower, and durability, I really thought the 1200 GS was going to be my top pick. After this video I'm scared. Are many of these serious flaws known among YT viewers? The later R1250 is too expensive, the 1150 and 1100 have less horsepower and Nm, I also find 5 gears little for highways. Greetings from Belgium.
Hi Deureka from Belgium 🤗…it does seem that the problems where on the 2005-2007 1200GS. Some say that there were faults in the valves in those early 1200 bikes. Not heard of any similar failures outside of those years. So you should be safe if you choose 2008 GS onward.
Aaron Li Hi Aaron, I have no idea, bit like when a plane crashes and they find a tiny flaw in some part I suppose. I am so relieved that the bike just lost power and Jason brought it to a controlled stop. Then managed to crawl it off the fast dual carriageway into a safe area.
This is just what you might have to do if you come across this situation. You strip down and clean as far as you have to before you scrap the lot or recover what you can. The piston will get a hammering @ 8000 rpm in a few seconds before failure for instance. Other than that I think it's f*cked!
Mine started making noise on the right side too. Damn it, 2018 9k miles. Is a new bike for me and started hearing a soft clicking noise on the right side. When I start the bike, it makes like a chain noise and goes away. I am in the middle of a trip. Is this normal? I hope I can make it home and check the bike there.
Hi Marcelo, You really should be OK. It was the 2005-2007 GS's that had a 'fault'. Never heard of one dropping a valve outside of those years. When you get back find my video on checking the valve clearances. It is simple to do and is a good place to start. I would be surprised if it was the cam chain? You will make it home OK I am sure😀
Wow. This makes me a little skiddish on buying a GS. Although I hear working on the newer 1200/1250 GSs are a lot easier. Kind of makes me want a super Tenere instead
@@normski3091 that's great to know. And thanks for the speedy reply. If I get one it will be a 2014 or newer. Seeing a video on how to do a valve check made me thing the GS us a much better option for those of us that like to do most of our own maintenance
Did not notice anything in particular, but the engine was such a mess, like a grenade had exploded inside. Buying a 2nd hand 2005 engine meant we just took the old engine to the scrap yard🤷🏼♂️
@@normski3091 Thanks for the reply. I was just wondering if maybe the Cam/Rocker arm issue, Ref: US 64011504-05 may have been the initial cause of the failure
Could never be sure but it really looked as if a valve had just dropped. Two valves had totally disappeared and the remains exhaust valves, bent up like a piece of spaghetti I keep on my workshop bench to remind me😵💫😱
Sad story, luckily it was only engine damage... I have exactly the same bike with 30,000 miles, affraid of having similar failure , Do you have any clue on why this happened or how it can be prevented? was it a tensor? broken chain sliders? defective/loose chain? low oil pressure?
Hi Carlos, yes you are correct, imagine at 70mph if the engine had seized in peak traffic, Jason would have been thrown off the bike! The damage of course was so great it is hard to find out what actually went wrong. However the chains and sliders appeared OK, both exhaust valves had disappeared. The input valves were still there but very bent. Never had a problem with oil pressure. The guy who runs a tyre changing mobile service here, Mark, is an ex Superbike mechanic. He says it is rare to ‘drop a valve’ on the road bikes but he has seen it a few times in the 2004-2007 models and always the right hand side cylinder.? What does that mean?? He said there would have been no indication or warning. On race bikes he has seen them blow the Cylinder head off. BMW chief mechanic said he had only seen it once in 10 years.
@@normski3091 Hi again. Do you think it would be a good idea, to put in New Valves around the 50,00 Mile Mark? I’m just wondering if that would save being worried about that happening. Thanks
@@joeybobbie1 hi Joey, thank you so much for watching my channel. I also thought I would replace the valves in the used engine I bought, until I saw the price.😱. If everything is running well I would not touch the valves🤔. I appreciate it is a hard decision because it does appear that there is a design flaw in the valve set up for these 2005-2007 1200 engines, but if you spend all that money and time what guarantee would you ever have that it had cured the problem. As one BMW engineer told me he had seen it once in 10 years. So a very small percentage of bikes, I would keep your bike regularly serviced and love it😍
Hi Anth, I also thought that a boxer engine would run forever! No I do not think it is common at all thank goodness, but I have discovered that it does happen especially in the 2004 - 2007 model of the GS. It also seems to be the right hand cylinder and around the 60,000 mile range? You do find threads on Google of riders experiencing the same. One thread was very interesting saying that there were a number of recalls by BMW on this model during those years to remap the fuel injection as it was running too rich (or the other way round). If Jason’s bike was not done, and there is no evidence, then maybe the valve was weakened over time, we will never know. As you could see the exhaust valves are not even there anymore. Here in Derbyshire we have a brilliant mobile motorbike tyre fitter, Mark Croft, who I always get to change my tyres. He was a Superbike mechanic for years and services and repairs bikes as a mobile mechanic. I rang Mark who says that dropping a valve is unusual for normal road bikes but he has seen it many times in the racing circuit, however he also assured me that it does happen and within 2 seconds will smash the inside to bits. Mark says we really have two choices: throw it away or buy an engine from a breakers.🤔
Blimey! Feel for your son with that going like that, but he's safe and walked away from what could've been a very nasty incident at that speed. Surely second hand engine would be the cheapest and wisest option? How much debris has gone elsewhere? Use what's left as a spares dept I reckon Norm. I hope it doesn't end up costing the earth for your son. That could be any one of us tomorrow god forbid! I wish you both well 👍
tojjer29 Hi Tojjer, yes what a disaster. A good fiend of mine, Mike, who now lives in Dallas, Texas and has been a chief engineer all his working life rang me yesterday. He said that the hole in the piston saved the rear wheel locking which would have thrown Jason off the bike at 70mph in heavy fast traffic. When you hear things like that then a broken bike is nothing. Mike said that the strain on the whole engine would have been so great do not even think about rebuilding it🤦🏼♂️
@@normski3091 It's true what a friend wrote, the rupture of the piston released the compression, thus releasing the rear wheel. If the piston had not burst, it would have been a tragedy.
@@RichiPM76 yes the more I think about it the more I think that is right. 3 of us are riding down to Triumph for the factory tour next week. If I have the opportunity I will ask the opinion of their engineers!
Ha ha, funny how your kids never actually say that. Jason has asked me to design and make a cable stripper for his washing machine rental business so he can get all the copper out of the old cables. A much bigger project than I imagined but very close now. Couple weeks and it should be finished🙏. What are dad’s for 🙈
R1200Rt engines much more cheaper... someone can tell me if I can put RT engine in r1200gs 2006?from outside looks completely same ,just 10hp difference 🤔
Hi RR, that is a good idea but I would be very surprised if it fitted. When I bought the used 2005 1200 GS engine the breakers were very specific that I had to get exact engine for the 2005 1200GS?
Hi Manuel, everything serviced correctly and oil changed even before due. The more I have searched and spoken to riders it is the 2005-2007 1200GS that seems to have an inferior valve that can drop and blow up the engine. Problem is that there is no warning. My son’s bike I rebuilt now has a second owner who loves it and no problems 🤗
So what caused the failure? I call B.S. that just happened out of no where un provoked.. he either got on it and started riding the hell out of it before the engine was all the way warm or he downshifted bad or forgot to upshift or just plain didn’t change his oil I put the wrong weight oil or perhaps his valves are just so far out of adjust that they actually had to contact but who knows I’m not all that familiar with these all I know is I got mine with 80,000 miles 84,000 actually and I’m at about 95 now I love it and I ride the shit out of it it has not failed or blown up like that on me. Thank God had to do starter alternator several tires couple spark plugs view valve lash adjustments all my gearbox oil like five times my final drive oil, my forks, I had to reseal the fork seals and put the oil there you know the good stuff I did a clutch with the clutch slave my windscreen broke so I had to break something up with that other than that she saw it. Front room is bent. I’m gonna have to figure that out the ungodly expensive
There was a fault on the valves and collects on some BMW 1200 GS bikes from 2005-2007. A number blew their engines to bits. My son is a brilliant rider who used his GS daily. I serviced it regularly never missed anything. The number of riders who have emailed me with blown up 2005-2007 GS’s 😵💫
Yes I often wonder that myself. It must be the same engine in the RT for 2005 - 2007 but I have never heard of an RT engine blowing up like the stories of the GS?? What on earth does that mean? I fitted the second hand 2005 engine into my son's GS as you see on the video and then sold the bike. Last year I heard from yet another owner who had bought the bike from a dealer and he said it was running perfectly. So it just seems that it is only a few bikes that fail? Of course you never know which ones🥵
I’d be absolutely gutted but there again it’s precisely why I avoid BMW like the plague. To own one of them outside of warranty hand without deep pockets is a brave man’s game. As you suggest with all that metal flying around at speed even a complete strip and rebuilt will guarantee finding every last bit so I’d personally have just swapped the motors out. Heartbreaking.
Yeah, I hate you just be a critic the whole time but you can reuse those clamps buddy, even though it says they’re not reusable ever use them and takes a little finesse
Let's appreciate that this gentleman in spite of all the shock has taken the time to show us carefully what happened. It's really sad.

Blimey! Feel for your son with that going like that, but he's safe and walked away from what could've been a very nasty incident at that speed. Surely second hand engine would be the cheapest and wisest option? How much debris has gone elsewhere? Use what's left as a spares dept I reckon Norm.
I hope it doesn't end up costing the earth for your son. That could be any one of us tomorrow god forbid!
I wish you both well 👍
tojjer29 Hi Tojjer, yes what a disaster. A good fiend of mine, Mike, who now lives in Dallas, Texas and has been a chief engineer all his working life rang me yesterday. He said that the hole in the piston saved the rear wheel locking which would have thrown Jason off the bike at 70mph in heavy fast traffic. When you hear things like that then a broken bike is nothing. Mike said that the strain on the whole engine would have been so great do not even think about rebuilding it🤦🏼♂️
@@normski3091 It's true what a friend wrote, the rupture of the piston released the compression, thus releasing the rear wheel.
If the piston had not burst, it would have been a tragedy.
@@RichiPM76 yes the more I think about it the more I think that is right. 3 of us are riding down to Triumph for the factory tour next week. If I have the opportunity I will ask the opinion of their engineers!
No.1.
Worlds best dad
Ha ha, funny how your kids never actually say that. Jason has asked me to design and make a cable stripper for his washing machine rental business so he can get all the copper out of the old cables. A much bigger project than I imagined but very close now. Couple weeks and it should be finished🙏. What are dad’s for 🙈
Great video
R1200Rt engines much more cheaper... someone can tell me if I can put RT engine in r1200gs 2006?from outside looks completely same ,just 10hp difference 🤔
Hi RR, that is a good idea but I would be very surprised if it fitted. When I bought the used 2005 1200 GS engine the breakers were very specific that I had to get exact engine for the 2005 1200GS?
What is the lift jack you are using?
It is called the Big Blue Bike Lift from Dave in Tamworth, great guy couldn’t be more helpful: on-bike.com/motorcycle-lifts
Catastrophic indeed.
Strange, do you use the right oil ? Change on time ? No ofense, i see u take good care of your bike.
Hi Manuel, everything serviced correctly and oil changed even before due. The more I have searched and spoken to riders it is the 2005-2007 1200GS that seems to have an inferior valve that can drop and blow up the engine. Problem is that there is no warning. My son’s bike I rebuilt now has a second owner who loves it and no problems 🤗
Important is your son is ok, sad is, BMW put faulty valves.
Yes Jason, my eldest son is fine. He could have been thrown from the bike into the traffic. 😱
He has given up riding which is such a shame 😢
So what caused the failure? I call B.S. that just happened out of no where un provoked.. he either got on it and started riding the hell out of it before the engine was all the way warm or he downshifted bad or forgot to upshift or just plain didn’t change his oil I put the wrong weight oil or perhaps his valves are just so far out of adjust that they actually had to contact but who knows I’m not all that familiar with these all I know is I got mine with 80,000 miles 84,000 actually and I’m at about 95 now I love it and I ride the shit out of it it has not failed or blown up like that on me. Thank God had to do starter alternator several tires couple spark plugs view valve lash adjustments all my gearbox oil like five times my final drive oil, my forks, I had to reseal the fork seals and put the oil there you know the good stuff I did a clutch with the clutch slave my windscreen broke so I had to break something up with that other than that she saw it. Front room is bent. I’m gonna have to figure that out the ungodly expensive
There was a fault on the valves and collects on some BMW 1200 GS bikes from 2005-2007. A number blew their engines to bits. My son is a brilliant rider who used his GS daily. I serviced it regularly never missed anything. The number of riders who have emailed me with blown up 2005-2007 GS’s 😵💫
BMW installing that flapper valve was the most stupid solution...many owner takes that damn thing off.
Paul griffiths had the same problem on his bmw,i think he was quoted £1200 he got rid off it and he would never buy another bmw.
Yes you are right. Normally 2005-2007 1200GS, there appears to have been a problem with the valves😱
What lift is that
Hi Ducboi, The Big Blue Lift : th-cam.com/video/D9MqCaIS-8g/w-d-xo.html
So it’s the same engine as the RT it’s the K 26 I’m just a couple different years are just not as good or what
Yes I often wonder that myself. It must be the same engine in the RT for 2005 - 2007 but I have never heard of an RT engine blowing up like the stories of the GS?? What on earth does that mean? I fitted the second hand 2005 engine into my son's GS as you see on the video and then sold the bike. Last year I heard from yet another owner who had bought the bike from a dealer and he said it was running perfectly. So it just seems that it is only a few bikes that fail? Of course you never know which ones🥵
I’d be absolutely gutted but there again it’s precisely why I avoid BMW like the plague. To own one of them outside of warranty hand without deep pockets is a brave man’s game. As you suggest with all that metal flying around at speed even a complete strip and rebuilt will guarantee finding every last bit so I’d personally have just swapped the motors out. Heartbreaking.
Just keep watching BikingChap....
Painful
The only GS s that are worth buying, are those with the name, Suzuki infront of them.
Your damn straight that’s not the best tool specially made socket i took a bench grinder to ask ordinary socket 😂
Wooo. 😔
Keep watching James 🤗😰
Ouch.
Certainly was Ken....and Jason my son decided to scrap the bike. But watch on and see what happens!
What the hell are you doing with that T ratchet handle I can’t watch. This is painful. Good day.
I think the rider over rev the engine.
No he didn’t
Yeah, I hate you just be a critic the whole time but you can reuse those clamps buddy, even though it says they’re not reusable ever use them and takes a little finesse
Sar I am Indian two wheeler mechanic sar I am Hindi main bhi aapke pass kam sikhana chahta hun aap meri madad Karen
Hi two wheel biker man from India. Great to hear from you and although I do not understand Hindi I hope you have enjoyed my videos 🤗
painful to watch
Beautiful GS? 🤣🤣🤣
Start looking for a good used engine.
70 mph! Hahahahahaha ya right
Wow! I’ll be following your progress with interest.
