Thanks for the kind words. Nice bike for a build, a K11! I would recommend you given that the engine has been standing still for a long time to replace all rubbers and gaskets. Chances are very real that they have dried out and or will crack if they will not be replaced
I could not afford the Older style air cooled in condition I wanted , so the K100 was all I could afford. I was very happy to find a excellent example of a 1985 K100 RT for $2000. It looks more modern, sporty, powerful and affordable. My heart is the old school air cooled motor , but 1985 is old school by todays standard. If I could afford both that's what I would do, but money and garage space only allows one. The K100 was more practical for me. BMW's are such a great value bike for the money it's truly hard to go wrong. It' s kind of like the model T vs a 1968 Mustang . I can tell you as people age the marks change. K bikes are becoming the modern classic bikes. Once it was the model T now it's the 68 Mustang and even those folks are passing on and a new classic will arise. The K bikes will have there day and it coming soon.
@@corner.custom I would like to buy a K100 tomorrow with 77000 km 1988. cafe racer . is this good choice for beginners ? This is very beautiful motorcycle that I have seen in my life.
Absolutely LOVE the rebuild you did on both of these motors, and I love both of them. BUT, if I had to choose I would go with the R100 because I just love the boxer motors. Also, I ride a 2013 Moto Guzzi v7 Racer so I just love those cylinder heads that stick out and say HI!
Unique video. Great craftmanship. Thanks for sharing. Difficult choice. I own both engines on K1100LT ‘96 and R1200GS LC ‘19. I’d like the Boxer engine a tiny bit more because of it’s uniqueness and character especially at low revs.
I am reminded of the answer to the question "What is the best bourbon?" The best one is the one you have in your hand! Get at least one of each! I am currently touring with the 100's little brother, the R80RT. However, I did the IBA 50CC on a K100. Jacksonville Beach to Ensenada in 40 hours and picked up the Bun Burner Gold (1500+ in less than 24) along the way. The K's are as smooth as a sewing machine! I am actually searching for a K75 and an airhead GS at the present time.
Couldn't have said it better. Both really have their own carastitics and have totally different way of riding. But TBH I prefer the torque and lighter overall weight of an R, makes the ride a lot more fun. Good luck on the hunt for good candidates!
Question; As you had the bike on a lift, was there any particular reason you didn't use it to not have to squat? It's not a criticism, I'm just wondering what the reason was.
Because I was building two engines at the same time I didn't had enough space to lay out all the engine parts and keep them separated from the R/K. At that time I also didn't had a bike which needed to be on the lift so I used it as a second working bench
Utterly lovely finish, how about a view of the finished bikes? I'm still keen on R series bikes, but the brick is more modern & has great longivity with more modern suspension & electrics. It's a very tough decision. I did try a modern R1150R at one time, a really lovely engine & gearbox that handled nicely for me. Decades ago I nearly bought an R80RT. I'm really a Boxer engine guy.
Thanks man. There are loads of videos of these bikes finished on my channel. The K engine/bike got a red tank and the R got a blue tank. When you liked this video, you'll most definitely love those videos as well. I'm currently working on a new build, a K1200
Don't you worry about that. The K100 gets all the cooling that it needs via the radiator and fan and for the R100, there's only Cerakote on the heads and cilinders, so no paint/issues right there.
Amazing job once again. Love reading the comments to figuring out what you use during your builds. Small question, where do you purchase al these new rubbers, seals, spare parts etc?
I fell in love with the R engine, especially when the bike lost a significant amount of weight with stripping down the fairing etc. The airheads are getting pretty hard to come by these days, especially for a decent price.
What is the risk starting the R100 after it had been still for a few years?...I've had a couple R100's been still and I start them ok...Check oil, plugs, fresh fuel or anything obvious, charge battery, try start... Thanks for any info....Thanks for the vid
Didn't knew if the timing was right or if the cilinders and or pistons where in good condition. I wanted to rebuild the engine regardless so there was no point of trying it and risk damaging parts
Im currently building a k1100. I chose the K for the performance aspect, ability to make more power with cams and a turbo, and keep up with modern 1000cc bikes. But i would still love to get my hands on an R100, im curious which one corners better
@corner.custom what a coincidence. That's exactly my plan for my k11. It's completely disassembled, doing gaskets and engine maintenance first. 200+hp is very achievable on the stock engine 😈 will be doing a front end swap from a gsxr 1000, hayabusa, or s1000rr as well. Planning a classic cafe bike with modern power. Make the young guns respect their elders 🤘
@DTM.Desperado ok nice man. Do you have a dedicated IG page for it? Love to follow it. I'm planning to make it into a sleeper. All fairings and suitcases on 👹
Wow, what parts did you all replace for the k100? I see all bearings but has to be replaced if you rebuild the engine? I have on too and am looking at rebuilding it but I don’t know exactly what needs to be replaced, do you maybe have a list?
I've replaced almost everything. The engine had not yet run a lot of km, but wants to prepare the engine for the coming years. When you do take everything apart, it is a small effort to tackle everything right away. There is a chance that if you leave something untouched, it will leak or tear later on. Then you have even more work to do than tackle it right at the beginning
The brick goes like stink in comparison... but the airhead is so more pretty to look at and easier to work on. My mate built a street scrambler K which I'm very fond of but I have restored a couple of Rs so my loyalties are with them. Btw I'm pinching your spinny cleaning brush idea :)
I feel you buddy, I'm more towards the R's as well. Love working on them, so easy to work with. Brush works like a treat, rinse with gas after and it's a easy clean 👌🏼

The R bikes sure are more expensive than a K bike. But I have to say the K's are also nice cruisers 😎

Thanks man👍🏼 I also go for the boxer, love the drive ability of the bikes. High torque at low rpm makes cornering so much fun!
Twin - I love 4 bangers but twins are just such a nice experience when riding.
I have to agree to that. Just love the torque at low rpm, makes it so much for exiting corners!

Great work! Bothengines look brand new! But as an R1150RT oilhead rider, i'd still go for the boxer..

I have both but I have to say it’s R’s that have the edge 😁
I agree buddy! Both builds are now ready, videos of those are on my channel as well
Hi
Should I plug the excess fuel drain at the bottom of the bmw r80 fuel tank?
No it's better to use it by putting a small hose on it, just like it is from factory
Very difficult choice, I love both of them, each one has its unique sound and ride 🙏🏻
They sure do! To be honest I like the R engine better, but that's also because of the riding position compared to the K bike
R all day -- it's so unique.

who makes the clutches for these engines? I would imagine that they have to cross reference to a few cars out there. insteadd of buying from bmw
The clutch packes are made by Sachs. The prices aren't that bad tbh 👍🏼
Is the paint blocking an efficient cooling of the engine ?
Don't you worry about that. The K100 gets all the cooling that it needs via the radiator and fan and for the R100, there's only Cerakote on the heads and cilinders, so no paint/issues right there.
@@corner.custom Thanks for the reply !
Appreciate your attention to detail, and your clean work area/presentations....Did you ever announce which engine you'd prefer?
Thanks buddy. To be honest I like the R engine more. Love the torque at low RPM, looks and sound 👌🏼
The K. But only just. You did a great job.
Thanks man! To be honest I like the looks and riding characteristics of the R more

Both iconic engines so tough to choose! The R100 is probably prettier but i really like the brutalist look of the K100
They both have their strong points indeed!
Welk product gebruik je om de motor te reinigen?
Hoofdzakelijk benzine icm een kwast in de boormachine. 2e video van de R100RS laat dat wel zien 👍🏼

They sure are bulletproof. Seen some K bikes with insane high mileage!
WoW, i prefer twin.
Same here man!

I have R100 scrambler and K1. Boxer is much more fun to drive because low torque..
I fully agree to this buddy!!!
Ik heb beide motoren een K100 8V en een R100/7 boxer elk heeft zijn eigen karakter
Klopt helemaal. Toch vind ik de R leuker rijden, meer beleving. Koppel bij lage toeren maakt het bochtenwerk leuk💪🏼
