Dear Sir please note I live in Australia and am now 65 years old in the late 1970's I had a BMW R80/7 model. I have watched all of the R90/6 series from start to finish and they have been an absolute joy to watch, thank you
You are something special. I have a R90/6 that has been sitting for decades. You have got me interested and confident that i can do it! Thank you William.
So useful and such a pleasant accent that many French can undestand . I own and maintain 4 airhead twins in the french South. Merci beaucoup Mr William!
These videos are great for their informational content, but almost as importantly, at least for myself, is that William and co. are able to transmit to the viewer a relaxed, clean and caring approach to mechanical work. There's love there. It's pretty awesome.
Can't thank you enough for mentioning (twice) that worn springs on the advance mechanism will prevent a a good idle from being achieved. Replaced them and problem solved. You are the best!
@@barryhope2953 I had to remove it. The springs are incredibly small, so I found it necessary to use jeweler's pliers and a lighted magnifier on a cantilevered arm to aid in the installation of the springs. Cheers!
@@jamesgault7383 Thought so. I have an idle problem and so was delighted to find that weak springs weren't doing very much with the arms quite loose and not returning properly. Was unable to fit a new spring in situ - so will take the ATU off tomorrow and do it on the bench. Looking forward to a normal return to idle.
@@barryhope2953 The 4 posts are wider at the top and I had a bit of trouble getting the end of the spring to go down past that point without harming the spring. It took me several tries to get it.
@@jamesgault7383 Just finished cleaning and rebuilding the ATU with two new fibre washers (one was missing!) and yes, putting those springs on was a bit of a challenge!
This is truly the best series i have ever watched. And having the exact same bike as an ongoing project, just makes it perfect. Thanks for a great tutorial guide about these cool airheads! Looking forward to the next.
I'm working on restoring anR90S, I was directed to this series by someone at Airheads.org. I've been wrenching on bikes for 50 years and Ihave to say this is probably the best TH-cam series I have seen. Both the ignition and carb balancing are the way I've done it for years. There is nothing as good as, a good set of ears frankly. Well done, this series will serve new airheads for years to come. Thanks
William and crew, I have been working on motorcycles and cars for 49 years including 5 BMW motorcycles which I've torn down and rebuilt including transmission rebuilding. In every video of yours, I learned something! Also, the way you taught and your enthusiasm made each video so very enjoyable. I am a repeat boxer2valve customer and sincerely appreciate all of you at boxer2valve!
You Sir are a wonderful and patient teacher. I really appreciate the time and effort you put into the video. Of great value to me with my '76 R90s that I re-commissioned after a six-year layoff a few weeks ago. Thank you!
Excellent videos! With a 1976 R90S headed my way - when shipping can be done - I decided to brush up on airhead maintenance. These video's are so clear to understand, camera work is excellent, and you are like a laid back professor to learn from. What a great way to pass time while in Corona lock down. DOWNSIDE: I am now wanting to buy an old airhead that does need some work to play/learn on. great work, thanks.
Some of the most , if not the most, informative and enjoyable / professional video I've seen. Been a Harley guy for years but I'm a happy new R100/7 owner. Quite a different animal. I love doing my own work so Boxer 2 valve is my new church. I've already made some adjustments and improvements and your knowledge and skill has been very helpful. Thanks
After a motorcycle accident has limited my riding for awhile, I bought a 1975 r90/6 out of a backyard storage container (we don’t have barns in the desert southwest). This series seems to be exactly what I need to get this awesome bike running. I can’t wait to get started. Thank you for putting this series together.
Thanks William and the team for these videos. As I am restoring a R80/7 and am new to BMW, this has helped incredibly. The workshop manuals are good but its as if I have someone in my workshop showing me what to do calmly. Excellent work guys
my father died recently and left me with his r100 CS '84, your videos were a great inspiration and a lot of information about putting the bike on point, thank you, keep the excellent work!
Found you just at the right time with time to spare(thanks to Covid).Relaxing ,informative & very pro.Getting my R80/7 ready for summer.Thankyou from the Alpes.
Great Series! You are truly inspiring. I just found Boxer 2 Valve (TH-cam and Web Site) after buying a 1976 R75/6 Sidecar rig. I've already made my first order of parts to rebuild the fuel system. Similar to your videos, I will be going through the bike little by little doing what needs to be done. The idea is to have a "survivor" and not a restoration. If I am down in the area (from Michigan), I'll have to stop by and say hello!
Thank You William for these videos. Since I've discovered you shop's website it my first stop for parts for my 1981 R100RT. Your shared videos even got me to re-seal the final drive this month. Thanks again and keep up the great work!
William, these videos are so great! I found your series after I wheeled my "78 R80 out of the neighbor's shed after 20 some years. Basically cruising along with your series for a Seattle winter project. Your explanations, tips and tool-making ideas are really helpful -thanks!
This series has really helped me with my R90S. I fixed a lot of problems with William's great advice- and have bought plenty of quality parts as well! Can't wait for the next series after the '85 Monolever.
You are amazing!!! Just went out and adjusted my point gap and static timing on my 1978 R100RS using the test light and volt-Ohm meter method. It's running GREAT now. The manual leave a lot out that you explain and demonstrate. THANK YOU VERY MUCH!
I just reassembled an entire motorcycle, time to take it for a ride and see if I forgot to tighten anything and hey, I'd better try to induce a wobble while I'm at it. Outstanding!
Just found you and the videos. I have a 93 PD, and the carbs are out - so you video is just what I needed. Great work without all the cursing some seem to think makes a video more watchable!
Love this awesome series, and you guys are amazing. William, you're a real guru when it comes to this stuff. The ending with the carb tune was so pleasing haha!
Superb! Have loved this series. Interesting, informative and extremely useful. Have a 76 90/6 myself. Many thanks for taking the time from me in the UK.. looking forward to the next one 😀
Thank you for creating this series. I have the EXACT same bike in my barn in pretty much the same condition. I have had it since 1991 and hasn't been on the road since 2004. I will be following your series step by step as I go along. I love the fact that you have all the parts and tools available on your website for each episode. I was going to make some modifications right out of the gate, but I will follow your guidance to make it a runner for a while first, then decide on tasteful modifications. Great job.
Henersonville is a great area; had a good friend that lived there from 95 - 00. I rode the area extensively on my 95 Triumph Trident. I haven't been back since about 99 - so I'm overdue!
This series has been so informative. I appreciate all of the knowledge you have shared, with your patience and kind/friendly tone. Feeling much more empowered to take on some of this work with my R50/5. Will also be supporting your business by ordering parts from you all here on out! Thanks so much for taking the time to do these.
Thank you so much for a top notch tutorial set, I have learned so much from you and am going to apply your teaching toward my restoration! please keep up the great videos and source the best parts available for our airheads....cheers.
Bravo William, thank you so much for all the work you and your team put into these videos. They are an invaluable resource. Looking forward to the next project.
Thank you William. I watched every one of your episodes and they were all great! I have a 1980 RS which I converted to an S, so looking forward to your next project.
Hello William! Many greetings and great many THANKS for all your excellent, calm and indeed very instructive videos, here from Denmark and from My 46 Year old, still steady running BMW R90S, Silver Smoke. One of the last produced ever, from Year 1976. "Only" yet 280.000 kilometers on the clock, with only one (!) main Motor overhaul, and actually not that big thing:: Main crankshaft and camshaft bearings still the original, and due respect for the ever running Duplex(!) timing Chain, including the old slash /6 big and heavy(!) flyweel. The last is indedd a good "adjuster", specially at idle, even if your Dellorto Carbs are not that fully syncronized ;.-) Pushrods still original too, apart from new rubber replacements. Only one major Cylinder overhaul at 150.000, with first oversize bore and pistons, etc. Apart from a single clutch repacement, and all other necessecary renewable things "along the road", such as all necesseary new fluids shifts. brake calipers, etc, nothing ever broke down on this incredible "ever running" machine. But please, everyone, treat these ever running 2 valves airheads boxers with due respect! Always remember words as GREASE (even every time you switch a tyre on both wheels (that is i.e. remembering grease the splines (backwheel) and the spindles, nuts, etc, Grease all whats need grease. And shift all our oils, in due time (or better before). The old Boxers will just pay you daily rinng respect, back ;-) My R 90 S have not needed any further overhauls. The bearings in the Gearbox are running rather noisy, though. (Maybe an instructive video, regarding dismantling the Gearbox shafts and replacement of the beasrings in the the gearbox would be great! Thanks in advance !!! :-) Shifting gears no problem, even on the old slash 5 and 6 Beemers. I Still wonder why so many -- even prof old BMW riders and even many experienced MC-magazines prof test-riders -- always reported abut noises, and missing shifts, etc. Rough Gearbox, etc. The Trick is pretty simple, with reference to own experience running /5 /6 and even /7 Beemers until the lighter flywheel, and the improved shift mechanism were introduced in 1981: During acceleration, pls take up the "free movement on the gearbox lever, just before you put the next gear in. Following this, you will shift without any noise , even during max accelerations! . It´s a bit more complicated when shifting down. Here you have to find the right RPM's , including a ½ second of some "in between gas/RPMs. But training also this, and you will find your own noiseless way, before even a harsh gearing down before a sharp turn! Every time I have changed my gearbox oil, I did not find any metal splines, even small ones, on the drain plug, which to my knowledge actually is slight Magnetizied, from BMW Motorrrad themselves, originally, (But anyway maybe not that Magnetizied, after 46 years :-) William, I will close my remarks as I started: THANKS so much for these very best, instructive, detalied videos ! If anyone contribute to keep these solid old 2 valve Bemmers still runnning, your videos are among the best. My respect & and keep on Running :-) Best wishes ! /Thomas
Thanks to these videos, I just finished switching back to the original Bing carbs from the Mikunis the bike came with. The project was fun and rewarding and it would have been a very different outcome were it not for your help and the quality products in your online store. My bike runs great now. Thank you!
great video, thank you! A customer reached out and I rebuilt his 40mm bings and when we got everything back together. No spark, at all, for no reason. I'll be checking the point(s) system as there really is no other explanation. We also replaced the $34 ignition module as well with obviously no luck. MUST be point(s).
It worthed every minute, as all your other videos. Thanks a lot! Really kind from you to take the time to explain and show everything. I keep tuned to see what it comes :-) all the best!
Un trabajo formidable, ilustrativo. Many thanks William!. Amazing!. The best “video series” on motorbike I watch ever. I have learned a lot meanwhile enjoying your nice job and explanations.
Thank you for making the videos, it is amazing what can be learned from a professional who has so much knowledge, I am restoring a R80 g/s 1980, and will adjust the carburetors the way you did....so excited in getting a old bike back on the road again.
Thank you for all the detailed instruction and fantastic camera footage to accompany the information. You’ve helped me revive an 86’R65 that a good friend of mine parked 10 years ago. My question is the ‘points in a can’. I am unable to find much information on the disassembly to get to the points. Would benefit me greatly if you had anything on that process. I like to have an idea what I am getting into as opposed to relying solely on a series of pictures on my phone where I inevitably miss an important step somewhere. Thanks again. Steven, Los Angeles
Steven: The points in a can is only on on 79 and 80 models. I always found that the best way to work on that system, is to remove the can from the bike. You can note the position with a marking pen for example before taking it off. Remove the top cover and then remove the upper shaft support. Now you will have easy access to the points and also the condenser. Remove the points, clean everything well and install the new points and set the gap to 0.4mm while its still off the bike. Then reinstall with a new o-ring and line up the marks you made. You will however still want to check and adjust the timing with a stroboscope. Hope that this helps!
Hi William, I ended up putting in a refurbished Ignition Control Unit (Hall sensor bean can). Is there any possibility I installed it 180 degrees off? The bike runs and is rideable, yet seems a little rough and has an unbalanced feel. Especially when cold. Also very difficult to start when cold. Feels as if it's running on one cylinder, yet both exhausts have output. Once it warms up it's better but not right. I have also soaked, scrubbed and rebuilt the carbs, new fuel line and included fuel filters, cleaned the tank and petcocks, new plug wires/caps, spark plugs, and ignition relay. Air filter, oil filter and engine oil are also new. I put a timing light on it and was able to get it on the Static mark at 1500 rpm. I set the intake and exhaust valves at .008 and .010. I know that's a lot of information as well as plenty of room for error. Any chance you can lead me in some direction on fine tuning it, or refer me to something I may have overlooked? Prior to this effort the bike had sat for over 10 years. 1986 R65. Thank you, Steven
Hello William. This is the best I have ever watched. Huge thanks for that. I just got a little bit lost. I watched so much from you. I thought you have one video where you sync the carbs and use a tool to redirect the spark, so It just runs on one cylinder. I can't find that video anymore. Can you help me out. Huge thanks, Paul
The parts I bought from you are great and the videos have been a god send. After following your bing carb rebuild and then this video to adjust these rebuilt carbs on my 84 R100RT but could not find the adjusting screws located where you were adjusting them from the bottom. So I finally realized my idle screw is on the top not the bottom 🤔 Love the videos keep them coming
Yeah, the 84 carbs are very different. We'll be doing works with the carbs on our current project, an 85 R80 and that will be relevant to your bike. Stay tuned!
@@boxer2valve The Bing 53's are now fixed and properly adjusted & synchronised. First I am going to rack some miles, than the leaky 4-speed gearbox will need some TLC. Understand you have some TLC-tricks up your sleeve for that, can you recommend anybody on the continent for that with simular standards of quality? Not the avarage BMW butcher, please.
Nice to watch and appreciate a true mechanic as well person who properly shifts a BMW vs the big name BMW shop below.

I found this series then bought a 74 R90 because of it. Thank you William and team for all the awesome content. FYI I was devastated when you mentioned you moved from Watsonville, I happen to live right up the road in Aptos. You mentioned on the test ride that the tach was bouncing and mine has the same affliction. Is the cure most likely sending it off to be rebuilt?
Yeah .... Sorry we aren't neighbors anymore . NC is good though ! Yes, it looks like it might be time for a tach rebuild . Thanks for watching Boxer2Valve !

Can't thank you enough for this series. Have been working on a '73 R75/5 since the spring and you have been indispensable. This week I have been installing new points but can't get them to open while manually turning the crank... any thoughts? Stumped.
Norman: You have the advance unit on right? The advance unit has two lobes. Position it so that one of them is in line with the rubbing block of the points and then move the base of the points such that there is tension and they open. Please submit a contact form on www.boxer2vailve.com and send some pictures if you can't get it sorted out.
You can see he loves what he’s doing.
Here I am frazzling over shorting vs vacuum methods, and it only takes two minutes for a pro to tune everything up by ear. Impressive!
it is a relief to find such a friendly and polite mecanic on the internet! thanks
Seems like someone it would be nice to drink a beer 🍺 with....
This guy is awesome!

Thank you for all your passionate and excellent videos. They inspire me to buy a R90S last week imported into the UK from the US.
Sounds great! Have fun with it!
Bravo William, thank you so much for all the work you and your team put into these videos. They are an invaluable resource. Looking forward to the next project.
Absolutely fabulous, informational and entertaining series. Thanks a lot for putting it together. 🙏
Brilliant, thank you very much from Dorset,England a great refurbishment.
Excellent video series, keep up the good work!!!
Thank you so much, William! I‘ve learned a lot. 👍🏼
Thank you so much for these videos. They are a tremendous help to this nooby R90/6 rider.

The Trick is pretty simple, with reference to own experience running /5 /6 and even /7 Beemers until the lighter flywheel, and the improved shift mechanism were introduced in 1981:
During acceleration, pls take up the "free movement on the gearbox lever, just before you put the next gear in. Following this, you will shift without any noise , even during max accelerations! . It´s a bit more complicated when shifting down. Here you have to find the right RPM's , including a ½ second of some "in between gas/RPMs. But training also this, and you will find your own
noiseless way, before even a harsh gearing down before a sharp turn!
Every time I have changed my gearbox oil, I did not find any metal splines, even small ones, on the drain plug, which to my knowledge actually is slight Magnetizied, from BMW Motorrrad themselves, originally,
(But anyway maybe not that Magnetizied, after 46 years :-)
William, I will close my remarks as I started:
THANKS so much for these very best, instructive, detalied videos !
If anyone contribute to keep these solid old 2 valve Bemmers still runnning, your videos are among the best.
My respect & and keep on Running :-)
Best wishes !

Thanks for the great input and we appreciate you watching .

My Pleasure! ;-) And we all appreciate your great videos
Thanks to these videos, I just finished switching back to the original Bing carbs from the Mikunis the bike came with. The project was fun and rewarding and it would have been a very different outcome were it not for your help and the quality products in your online store. My bike runs great now. Thank you!
Great to hear! Thanks for checking our videos out.
Love your work! You have helped me so much in setting up my 75/6, very informative- Cheers from Australia
Thanks, great tutorial. Looks like a beautiful town.
🇩🇪brilliant keep up the amazing work and a big thank you for teaching me so much 👍🏻👍🏻
Glad we can help!
Brilliant series, you are a true gent, looking forward to starting my /6 overhaul.
Thank you very much, William. This series helped me get through my /5 project bike.
Great to hear!
great video, thank you! A customer reached out and I rebuilt his 40mm bings and when we got everything back together. No spark, at all, for no reason. I'll be checking the point(s) system as there really is no other explanation. We also replaced the $34 ignition module as well with obviously no luck. MUST be point(s).
It worthed every minute, as all your other videos. Thanks a lot! Really kind from you to take the time to explain and show everything. I keep tuned to see what it comes :-) all the best!
Very cool man!! Have been following your videos for some time. Glad to see her running. Safe travels
Epic series! Thank you very much!
Looking forward to the next one!
Excellent videos you post !!
Un trabajo formidable, ilustrativo. Many thanks William!. Amazing!. The best “video series” on motorbike I watch ever. I have learned a lot meanwhile enjoying your nice job and explanations.
Thank you for making the videos, it is amazing what can be learned from a professional who has so much knowledge, I am restoring a R80 g/s 1980, and will adjust the carburetors the way you did....so excited in getting a old bike back on the road again.
Thank you for all the detailed instruction and fantastic camera footage to accompany the information. You’ve helped me revive an 86’R65 that a good friend of mine parked 10 years ago. My question is the ‘points in a can’. I am unable to find much information on the disassembly to get to the points. Would benefit me greatly if you had anything on that process. I like to have an idea what I am getting into as opposed to relying solely on a series of pictures on my phone where I inevitably miss an important step somewhere. Thanks again.

Steven: The points in a can is only on on 79 and 80 models. I always found that the best way to work on that system, is to remove the can from the bike. You can note the position with a marking pen for example before taking it off. Remove the top cover and then remove the upper shaft support. Now you will have easy access to the points and also the condenser. Remove the points, clean everything well and install the new points and set the gap to 0.4mm while its still off the bike. Then reinstall with a new o-ring and line up the marks you made. You will however still want to check and adjust the timing with a stroboscope. Hope that this helps!
Hi William,
I ended up putting in a refurbished Ignition Control Unit (Hall sensor bean can). Is there any possibility I installed it 180 degrees off? The bike runs and is rideable, yet seems a little rough and has an unbalanced feel. Especially when cold. Also very difficult to start when cold. Feels as if it's running on one cylinder, yet both exhausts have output. Once it warms up it's better but not right. I have also soaked, scrubbed and rebuilt the carbs, new fuel line and included fuel filters, cleaned the tank and petcocks, new plug wires/caps, spark plugs, and ignition relay. Air filter, oil filter and engine oil are also new. I put a timing light on it and was able to get it on the Static mark at 1500 rpm. I set the intake and exhaust valves at .008 and .010. I know that's a lot of information as well as plenty of room for error. Any chance you can lead me in some direction on fine tuning it, or refer me to something I may have overlooked? Prior to this effort the bike had sat for over 10 years. 1986 R65.
Thank you,
Steven
Thank you so much. This is what I really needed. I have seen many videos but you could explain very easy everything.
Greetings from Colombia
Great series I really learned a lot thanks for putting this together. Looking forward to the next series.
Fantastic! SO appreciate the time ,effort and expertise. What a gift.
William, simple Great. Thanks to you. Best whishes from Southern Germany. BR Franz
Many thanks!
Hello William. This is the best I have ever watched. Huge thanks for that. I just got a little bit lost. I watched so much from you. I thought you have one video where you sync the carbs and use a tool to redirect the spark, so It just runs on one cylinder. I can't find that video anymore. Can you help me out. Huge thanks, Paul
The parts I bought from you are great and the videos have been a god send. After following your bing carb rebuild and then this video to adjust these rebuilt carbs on my 84 R100RT but could not find the adjusting screws located where you were adjusting them from the bottom.
So I finally realized my idle screw is on the top not the bottom 🤔
Love the videos keep them coming
Yeah, the 84 carbs are very different. We'll be doing works with the carbs on our current project, an 85 R80 and that will be relevant to your bike. Stay tuned!
Awesome Video peeps... soooo professional and informative... we need more !!!!!!
Great Videos that you ( and your Team) had made. I learned many things. Thanks and greetings from Germany
Love these videos very informative and a great help for anyone with an old airhead keep it up👍👍
Thanks William a great video helps my confidence working on my 1978 R100/7. Keep it up!
Thanks very much! We will do our best!
Best TV in a long time, thank you very much William! I could do with some tips on the Type 53 Bing carbs, hopefully on the next project.
Thanks. No plans for Type 53 anytime soon but you can give me a call if you need some help. I will do what I can.
@@boxer2valve The Bing 53's are now fixed and properly adjusted & synchronised. First I am going to rack some miles, than the leaky 4-speed gearbox will need some TLC. Understand you have some TLC-tricks up your sleeve for that, can you recommend anybody on the continent for that with simular standards of quality? Not the avarage BMW butcher, please.
That was a fantastic series, thank you so much! You have inspired me to try a DIY bike project (one of these days)!
You guys are awesome! Thanks for sharing you knowledge with the world, I know its been a huge help to me during my /5 project.
Great to hear!
Thanks a lot, very needed tips or ways to do things. very helpful
Love it , just like my R 90/6 , nice Videos , lot of information
Thank you for your great detailed info that you give us. It really is a great tutorial
Glad you enjoyed it!
William thanks this is a great great help to me right now I am doing the same steps on a R80 TIC love your video they are really pro
You do such a great video, how can I get part's from you
Maybe I should take over my uncles R45 after all!?! Great videos!
Danke William Du bist der Meister
Nice to watch and appreciate a true mechanic as well person who properly shifts a BMW vs the big name BMW shop below. Note video below crashing the box;th-cam.com/video/0RRha-iSMd0/w-d-xo.html
My 75 R90/6, 76 R90s, 70 R75/5 and 66 R27 shift almost silently 90% the time.
Learn to properly shift a BMW, it's not a Harley. Bring A Trailer today 6-5-21 75 R90/6 auction sold $18,906, 12,880 original mile......~~=o&o>......
Fantastic videos. Thank you . Cheers
I found this series then bought a 74 R90 because of it. Thank you William and team for all the awesome content. FYI I was devastated when you mentioned you moved from Watsonville, I happen to live right up the road in Aptos.
You mentioned on the test ride that the tach was bouncing and mine has the same affliction. Is the cure most likely sending it off to be rebuilt?
Yeah .... Sorry we aren't neighbors anymore . NC is good though ! Yes, it looks like it might be time for a tach rebuild . Thanks for watching Boxer2Valve !
Bravo !
Can't wait to see the '85 R80RT project... but I want to keep my RT fairing .......

Great videos, thank you.
Is a fuel filter after the petcock really necessary?
Can't thank you enough for this series. Have been working on a '73 R75/5 since the spring and you have been indispensable. This week I have been installing new points but can't get them to open while manually turning the crank... any thoughts? Stumped.
Norman: You have the advance unit on right? The advance unit has two lobes. Position it so that one of them is in line with the rubbing block of the points and then move the base of the points such that there is tension and they open. Please submit a contact form on www.boxer2vailve.com and send some pictures if you can't get it sorted out.
These videos are awesome! Love the info and tips.....but where do I get a pair of those overalls!!
gracias por compartir el arte de puesta a punto a una joya clásica de la ingeniería.
