Tip from an old German mechanic I knew, oil control ring gap goes at noon on r and flying brick k bikes, prevents oil leaking into the cylinders when on the side stand
Very important to always check oil flow supply, from top two cylinder studs to rocker shafts. This is done, before affixing the rocker covers, by turning the bike over, via the starter button. Most important not to omit this process, as major engine failure may ensue, due to oil starvation.
as a photographer never use AF for stationary work. just set your aperture (depth of field) to around 5.6-7.1 and you will never have it searching for focus because you will be using manual focus
Taylor, you may find this interesting, hopefully you do. In the late 70z, I was BLESSED by going to every Advanced class at Honda Motorcycles, private school. Two of the other students had just finished up at BMW school. Our Professor confirmed with their Professor, that what they claimed was indeed true. This being that at the time, BMW factory had a recommended procedure for cylinder prep for new rings. You sitting down ? You submerged the cylinders in water, and then set out to air dry, after a set period of time, they of course, developed a light coating of, you guessed it, rust. The factory engineers claimed this ensured, break in. I'm NOT joking. Remember that piston ring technology is light years different now from the cast iron rings of the 70z. I've been Building Race Engines for decades, and yes, rings dry, light coat of oil on the cylinder walls. Good job. T.S. RACING
to help with an issue that doesn't really exist, what about leaving an old ring in the third ring groove when your pressing the the piston into the bore to square the new ring when checking for ring gap
Bing International has rebuild kits available in a few different configurations, depending if you want floats and diaphragms with the kit. The hardest part of the rebuild, and it didn't look like you completed that, is replacing the carb o-ring on the throttle shaft, as you have to grind off the ends of the butterfly screws and peen the screw ends when you are done.
Most use a thin coating of Hylomar or similar sealant where the head meets the engine block to keep any oil mist/seepage from collecting at that junction. Might not prove to be an issue but will be interested to hear a follow up on how this pans out for you. Hope it's not a problem. There are a number of methods and gizmos to assist with balancing the carbs. The most simple and effective, I have found, is shorting one side, using shorting rod on each plug and a screwdriver to short/ground one side. Careful that the screwdriver touches both the shorting rod and head ( as a ground) so the excess voltage does not fry the ICU. Dial in fuel mix/idle equally on each side while the bike is running and it's nearly spot on that way. There are other methods that are effective as well. This era of Bing carbs have a vacuum port for any typical carb sync gizmo. Good luck and wrench on!
You can buy some fancy gadgets to sync the carbs, I use a simple manometer I made with a length of 5ml clear hose and some ATF fluid, it's very sensitive and works perfectly or syncing. Love the bike I want one of those. Mine's a 1994 R100rt
Ring was probably broken upon installation even at the factory. You could have possibly ran it a long time with the broken ring. It was probably still working to a degree especially with the spring behind it. The second ring is an oil scraper anyway. Good thing you took it apart!
Hi Taylor, enjoying the content very much. Just getting my licence shortly at 63 years young. I really like the Honda CB550, but not committed yet. What do you think of the build quality of BMW’s based on what you’ve found so far compared with Honda. Keep up the great work. Malc from England.
Those ports were also on my R1100S, and did accept a manometer to measure comparative vacuum. You need fans for the engine. The "S" had throttle bodies and the manometers were sensitive enough to show minor air leaks on the throttle valve pivot pins. Throttle sync. was basically manual AFAIK working on the activating arms.
For example, I like to use two-stroke engine oil for assembly. Its specific burning smell tells me whether it is burning assembly oil or - unfortunately - the renovation was unsuccessful;)
I just bought an '89 Honda Transalp, I'm wondering where are some good places to find OE spec parts for it. Is everything going to come from China, or is there a better resource with a wide enough scope for these old bikes?
Lovin' the series on this Beemer. Would it not have been better to keep the two carbs separate instead of mixing the components in the parts washer or doesn't it matter?
It is... BMWs engineers made the engine so well that they have basically used the same engine for a 100y soon. Ofc it's been upgraded along the way but it's a engine you can repair even in harsh conditions on the road. And like almost any motorcycle engine it's almost bulletproof
awesome video! What do you mean by "today's fuel" ? I would think that with the added alcohol we have here in Europe at least, it would auto clean the carbs rather than clogging them wouldn't it?
The problem isn't only the jets per say Sir, that are negatively affected by the ethanol. The aluminum carb bodies, the float bowls, and especially the passageways in the carb body that is most affected. Ethanol, oxygen, and aluminum left standing is not a good combination. In the U.S. we have many fuel stations that offer ETHANOL FREE fuel.
Love the channel …. Any chance you could find and restore a 1973 Suzuki GT250 😉 Working on one, so could use some guidance :) Not many videos out there on those old 2 strokes …. Cheers from Vancouver Island, BC Canada 🇨🇦
I had to chuckle when you kind of surprised that it fired right up. It's an Airhead. That was before they started building bikes with expensive defects built in at the factory. How bout a quick look at the last good looking car Chevy built outside.
I wonder what a BMW shop would have charged for all of that work?????? It may be a little scary.......nothing is cheap in 2022......you don't mind paying quality work....hope your mechanic is as thourough as Classic Octane.

That makes good sense

What a gorgeous old war-horse! Don't even think about Baba'in, Bob'in or Brat'in this classic.
Installing it dry is really not an issue. It will be oiled within the first stroke. BMW boxer engine is such a sweet thing to work on!
Very interesting watching a guy who really knows engines working on a BMW Airhead without prior Airhead experience.
I'm loving watching you Wrench on this airhead.
Really nice bike Taylor, you did well in buying that .....👍
Cool ring pliers. Not seen those before.
as a photographer never use AF for stationary work. just set your aperture (depth of field) to around 5.6-7.1 and you will never have it searching for focus because you will be using manual focus
I love air cooled boxer engines especially the old ones, well done buddy! Regards from Germany

Thanks for showing the machines you used for cleaning and also the top down views. Looks great!

'78 R100RS here. Bought almost new and still going strong 42 years later. I do the same carb syncing method.
I like to bench sync with a drill bit before putting the carbs on a bike. Helps get everything close initially.
Forgot to add, great work, some people don’t tackle bmw , they are totally scared of them, it’s just 1930’s technology
Great work and interesting to watch. Would love one of the P-D GS (especially in that White/red colour) to compliment my R100RS and K1 😊
Ring was probably broken upon installation even at the factory. You could have possibly ran it a long time with the broken ring. It was probably still working to a degree especially with the spring behind it. The second ring is an oil scraper anyway. Good thing you took it apart!
Awesome bike. Would be great to have your own vapour blaster.☹
Enjoying your vids in Victoria, Australia. 👍
What soap/chemical are you using when you clean the carbs? Is it a mix or straight from a bottle?
Inmaculate cleaning to those carbs, excellent job!
Nice bike! Check out Boxer 2 Valve they have carb rebuild and sync videos. Very well done.
Piston rings go in dry in my shop also.
I am so jealous of that bike!

Should be vacuum ports down stream of the carbs pretty straight forward process
Those ports were also on my R1100S, and did accept a manometer to measure comparative vacuum. You need fans for the engine. The "S" had throttle bodies and the manometers were sensitive enough to show minor air leaks on the throttle valve pivot pins.

Still love carbureted bikes!😎👍
A lot of engine builders feel dry ring install results in almost immediate seating of the rings.
Crowbar technology. Well done!
I'm surprised you didn't use any assembly oil for putting any of the moving parts together
For example, I like to use two-stroke engine oil for assembly. Its specific burning smell tells me whether it is burning assembly oil or - unfortunately - the renovation was unsuccessful;)
Dude, that was great!!!!! Looking forward to your next video!!!!! Very cool bike!!!!!
Did I miss it in the last vid, or did you not change the rings in the left jug? Just wondering.
I just bought an '89 Honda Transalp, I'm wondering where are some good places to find OE spec parts for it. Is everything going to come from China, or is there a better resource with a wide enough scope for these old bikes?
Very cool bike. 👍
For a guy who has never worked on an airhead, you rocked it! Is that bike one that you'll sell? I'd be interested. I am an airhead addict. :-)
Good job Taylor!
Interested that you didn't do a quick glaze-busting hone before assembling with
new rings ???
It's a nickel coated (Nickel-sil) cylinder. It should never be honed.
Nice job so far
Lovin' the series on this Beemer. Would it not have been better to keep the two carbs separate instead of mixing the components in the parts washer or doesn't it matter?
Most of the parts are interchangeable so it doesn't matter for the most part.
What was that rattle at lower revs (16:42)?
Hopefully something on the lift ratteling.
Would love to see you build a old school chopper (raked and hardtailed cb400t or 78 cb400a hondamatic complete build 🤔
Keep up with your videos
Thanks again
I’ve never worked on a bmw before. Looks easier than working on a ujm 4 cylinder.

Are you keeping this one Taylor? I know you just picked up the Kawi not too long ago
Is the parts cleaner you use the 10 liter size that is listed in your Amazon section?
Do you have balance sticks
Great stuff man
brilliant thank you
Did you put new wrist pin c/clips on?
Ooo do I spot a 1200gs in the back?
awesome video! What do you mean by "today's fuel" ? I would think that with the added alcohol we have here in Europe at least, it would auto clean the carbs rather than clogging them wouldn't it?
Ethanol in the fuel makes it break down rather fast if the bike sits for an extended time, leading to clogged jets.
@@90blacknight Yup. I can buy real gas, no ethanol, here in Virginia at select gas stations.
The problem isn't only the jets per say Sir, that are negatively affected by the ethanol. The aluminum carb bodies, the float bowls, and especially the passageways in the carb body that is most affected. Ethanol, oxygen, and aluminum left standing is not a good combination.

How bout a quick look at the last good looking car Chevy built outside.
The engine seems to be chattering quite a bit... wonder where that’s coming from?
It goes away when I pull the clutch so my guess is clutch release bearing. Not sure if they always make noise on these or not.
Taylor is a no lube type of guy.
I spy another bimmer in the background...whats that?
What's that tattoo on your left arm? 1932 Ford coupe maybe?
I wonder what a BMW shop would have charged for all of that work??????
It may be a little scary.......nothing is cheap in 2022......you don't mind paying quality work....hope your mechanic
is as thourough as Classic Octane.
A little bit surprised you don't at least wipe the cylinder with oil of some kind
