- A very wonderful person gave me this 1974 BMW R90 Motorcycle. It hasn't run in a couple years but I kick start it! Hopefully I didn't break anything... weird that the kickstart gets hung up. Stay tuned as I fix it up and get it back on the road! Brake master cylinder disassembly and gas tank flush.
The part at 3:40 is used to hold on the rear tail light from inside the trunk in an 02! love the bike and 02
Dude great job!!
In the UK we would call you a 'Jammy Bastard'....That's not a derogatory term here...It's a friendly shout out to you for being so lucky...Big thanks for the video...Great people giving strangers gifts is a wonderful thing and great to see that you know what you got there and how to bring the old girl back to life...Good luck and happy riding!
Thanks cheers from across the pond man
One of the most beautiful bikes in history.
I agree they're pretty!
the paint on the tank is amazing for that age. You are a lucky bloke, and obviously someone who treasures the 'story' of a classic bike.
I got very lucky, it's an awesome piece of history. Ride safe
That is a killer bike ! You are so lucky .
Your grandfather had good taste in motorcycles . stay safe .
Thanks man ride safe
What a wonderful score! Great to see something like that land in the hands of something that clearly appreciates it
I'm blown away! Beyond appreciative! Thanks for watching more stuff is on the way
Great buy...by all means, keep it. I still have an R90S that I've had since the 1980s, and it gets ridden every week. Original dampers for that bike were Boges, the Konis were upgrades. DEFINITELY clean the carbs; those things will never run properly unless you do. Look on the bright side: if you blow the engine, the tank (after cleaning and creaming) is worth about $300!
The master cylinder is a work of art, like Otto put it together at his work bench.
Super unnecessary but cool for sure
Wow Benjamin, that's an unbelievable price, and the Beemer is in great overall condition. Good luck with getting her back on the road.
She's out and about man! Thank you!
You had a really good day , what a score
best day ever man
You'll get it, time and patience. I was fortunate to be handed down my grandfathers 83 r65, it sat for years. I spent probably 3 months so far this year, doing what you have, piece by piece, finding new, but little problems every step. Tear those carbs apart and have a look at least. They aren't hard to rebuild. I threw in the towel and bought all new orings and gaskets for mine. It fired on the first try and after adjusting and syncing it starts very easily. This is my first bike, and it has been very educational finding and repairing everything. Great looking bike, enjoy it.
That's awesome man thank you for sharing! So cool that it's staying in the family!
You Sir, are a genius! Enjoyed the vid, reminds me of my youth
Your words are kinder than I deserve! I'm so glad you liked it!
I just had to disassemble a starter because brake fluid go into it, too. Had to clean everything, inside and out, down to bare metal to remove corrosion. Starts great now.
That's a bummer but I'm glad you got it fixed man
Score of a lifetime!
No kidding I feel very fortunate!
It's straight, complete and not rusted out. That's all that really matters when acquiring a classic anything....especially a $5 classic. You could sink a lot of money in parts in this bike and still be easily ahead. (the action on that kickstart definitely indicates a problem)
Absolutely, rot and warp are hard to deal with.
Just started watching your channel.
With those braided fuel lines you don’t need clamps. Next time you remove the pet cocks throw those screens in the trash. They get clogged and cause problems. You added in line fuel filters that is enough.
Also consider altering the negative battery lead. Where it attaches to the engine case cut the eye into a U. That way you just loosen the bolt and pull the negative cable off. It saves time and works well.
If you’ve already gotten those comments sorry to repeat. I’ll keep watching and leave comments along the way.
BTW, a 30’ road flare fits nicely in the frame tube under the gas tank. Always good to be prepared. Good luck.
Thanks for watching and the tips
Starting a BMW by kickstart: Both feet left and right on the footrest. While standing on your footrests you put your left heel on the kickstarter. Press the kickstarter down until you feel comprssion, relase the kickstarter and then kick it. Why this way: If the engine backfires, the kickstarter will shoot out from under your heel. The way you do it here, you can't apply force and you run the risk, in case of a kickback, that the kickstarter will hit you right under the middle of your foot.
Dude that was fun. Way to keep at it!
Thanks for watching!
Boxer2Valve supplies parts and has a rebuild guide on this exact model. Things that may seem lost like those petcock strainers are actually available.
Nice, good tip
This things were built to last!
I agree man
subscribeded, had me a 5 dollars
Thanks man I appreciate that
BMW used red anti-rust paint inside the tank, think its gone now 😂
Excellent video brother,
Makes me want to get my 98 r1200 ready for spring time.
And that you for the gas tank clean out.
That's first on my list for Saturday morning.
Best of luck ride safe
You have most defiantly worked well and earned this now fine & fits nice BMW bike .
Regarding your oily sump - my 1969 R69S crankcase was always slightly oily from oil seeping straight through the porous aluminum. In your case, from the video, it looks to me like this 1974 has the same, cough, 'quality'. If I'm right, it's not a oil leak that you can fix but rather oil seeping which is "normal" for this era. There might be oil leaks too but the even, horizontal coating of oil all over the sump at oil level looks odd for an oil leak.
Back in 1938, driver Rudolf Caracciola in the Mercedes-Benz W 125 twelve-cylinder established a world speed record on a public road reaching 432.7 km/h on the autobahn near Frankfurt. Many decades later that car still exists and the metallurgy was tested and found to be on-par with inexpensive, modern garden furniture. It took German industry a LONG time to recover from WWII.
Awesome information thank you for sharing! I love hearing about stuff like this!
Can't wait to hear it run .
no need to wait check it out ruclips.net/video/Nk9cvaFYUYw/видео.html
This was rad. Super jealous of the price! I'm also documenting my /6 build and it seems we ran into similar issues. Excited to see what comes!
Thanks man!
Good job
Thanks man!
Carbs would've needed disassembly too .. their jets are most likely clogged with crap .. otherwise an awesome bike .. getting one in such a good condition is like winning the lottery 👍😆
Thanks man! It's been running good!
Dang! I thought I did good recently getting a 75 R75/6 for $600, Im still going thru some things but shes running and driving! Nice video!
No you did great man congrats on the new bike!
No worries. Airhead Beemers are as easy to work on as a VW Beetle. Great Score!
Thanks man!
Lucky man!
Yes sir!
Looks like the starter solenoid that keeps the gear engaged is not working only the one that moves the gear into position is working hence the hunting
Diesel, kero or plain old petrol ...anything BUT water dude ! Dave
Distilled works good for me
My r80 7 had same problem replaced the starter it fired up brilliant
I'm hunting down the weird relay problem that I think it might be, if it's not that then I'll probably do the same as you!
@@10mm it drove me around the twist this problem starting then I bit the bullet stripped it down tested the starter it was very slow ,too slow to turn the engine over new starter in job done ,I thought it was starter relay etc ,good luck with it its a lovely bike and they're fantastic to ride handle brilliant 👍
@@10mm they are great bikes to tinker with I enjoy working on it changing oil etc prob the last bikes you can do this on ,can't imagine doing this with a modern bike
@@shingerz Modern stuff can be annoying that's for sure haha
Thats funny. In the 1980 i had a metallic brown R 90/6 with 2 front discs and also a (golf-)yellow 2002. Greets from Munich/Germany. The handle bars of yours are from a R 100/RS (wich i had after the 90/6), the OEM rear shocks are Boge with aluminum sleeves on the top. I think, the plastic nuts from the tank are to find on the fuse box of the 2002.
Hey thanks for sharing man cheers from across the pond
Those are the new petcock screens that are better than the original. The red washer is not used because the metal waser is aluminum and it will seal with out the gasket. They also fit better without the red washer.
Fuel line looks recent. The size is 7 mm. 1/4" is too tight and 1/3" too loose. The proper fuel line is available many places including Volks Wagon shops. I don't run fuel filters. The screens do a good enough job. But many do believe in the filters.
Her undercarriage is a little hairy...
It was the 70's after all. 🤣
haha exactly
Owned one for a long time - a '76. Awesome bike. Mine had the bigger touring gas tank. Yours is the cooler, earlier metal turn signal and with kick start. Enjoy it!
Thanks man!
Cleaning Vinegar works better to get rust out. MEK will get rid of the tank liner.
Good call, thanks man
That sound is solenoid bounce due to inadequate battery charge. Second bad sound was you leaving the kickstart down causing the pawl to rattle on the gear.
The original tank liner is a rust red color. Looks like that is what is coming out. There are several companies that make tank liners. I like the one from POR 15.
I like their epoxy based stuff it's tough ceramic like almost
SCORE !!!
Hell yeah
Goes to show, many things just need some TLC (Tendor Love and Care) to get them up and running again.
Yes sir!
As a former tech and owner since 1974... your will find the following: If you ride a lot the valves will have to be replaced as they were designed to run with LEADED 95 octane gas. You might have to disassemble the transmission as there are known issues. Yep, the kick starter is only for extreme emergencies. You would be better off to push start it. The ignition is weak... so keep the points burnished & the points cam lobe lubed every 5,000 miles. The charging system is also weak. One crank for a good running engine.... well it takes about 15 minutes above 1800 rpm to put back what was used in that SINGLE cranking. There is an aftermarket diode board... that helps some and is more reliable. After 50+ years of drinking the BMW cool-aide... I prefer reliability and not have to always work on the bike...so I switched to Honda & Suzuki. Don't get me wrong.... I still love that R90/6 and my 1977 R100RS cafe. I am worn out from having to always fix or tweak something.
Thanks for all the knowledge, I'm a big fan of UJM bikes as well. Ride safe man.
NICE
Yes sir!
I miss kick starts...I know....i know...but to have that assurance of, if everything goes wrong you still have a possibility not to push it...
Same here man!
Salut my friend super moto super video subscribe subscribe .
thanks man
I would not have bothered with the under-tank cable-operated master cylinder. I would have gone for a post 1981 handlebar mounted one as they are far more efficent
I considered it. But man I love the hand levers on this bike
A lot of owners mistake BMW's very poor choice of velocity ratio for low efficiency. A few owners (not me) have had the master cylinder re-sleeved down to 14 mm, and report much easier braking.
Any progress on the bike?
Yeah it runs good! ruclips.net/video/Nk9cvaFYUYw/видео.html
Doudt it is a total loss lub system it's an old German bike, check valve push rod tubes for leaks.
Oh they're leakin
Tickle the carbs
Check valve clearance, and plug condition.
I wouldnt use that Kickstarter. The ks gear has a soft metal gear in the train which ends up in time, loading the transm with metal dust that gets everywhere. Not healthy for the transm. For anybody that has tried using the ks on these bikes, you having just taken the first step in disabusing the notion of German engineering. Charles
Good to know thanks for the info
Good soup 😊
how on earth do you find such a deal? honestly? Anyone owning this bike would know better, please tell.
if you are thinking of selling it let me know!
It was in the craigslist free section and I saw it within the first 5 minutes. Offered the owner money and they turned it down. They just wanted $5 to mail me the title at a later time
@@10mm wow, I have been looking for a r90 at a reasonable price for like ten years,.
Good on you to find some honest people.
@@Coyotehello Once in a lifetime thing I'm sure, I feel very fortunate. Best of luck on your hunt!
@@10mm Yes, my earlier comment was totally to say Kudos to you mate, good find and a proof that there still good fair people in this world that will just pass good things to good people.
From your other video, the transmission ina /6 is a 5 speed. The 1974 year had a ruff time of it being the first year of the 5 speed and when that one went bad they put a /5 transmission in it. The 4 speed/5 trannie also seems to need work. The lever is supposed to pop back up. If you have the original '74 5 speed it may be rebuildable but many time they are not. Unique parts not shared by any other 5 speed is the enemy. Any 5 speed from 1974 thru 1980 will fit. '81 and above 5 speeds do not fit. They have a shorter input shaft and the work arounds are not worth the time and money..
Also from your second video you have noticed the lack of performance of the front brake. Too bad you didn't do a little more research because this is a common complaint and the best fix is to reduce the size of the MC when rebuilt.. The bike is rideable with the original brakes, I rode mine 20 years that way, but it will be something you want to address after you fix the transmission issues.
You need a manual. Clymer's is good. Also the one from England. They eacbh cover a little bit of different area so they go together well. The BMW shop manual is expensive and not recommended.
There are several online Forums and email lists. I recommend -- advrider.com/f/forums/airheads.85/
It is probably the most popular.
And I thought the Passport was a score?!
Bro, so stoked for ya! I can just imagine how you felt getting that started. I'm glad I stuck around til you did
Crazy find man thanks for watching!
Old Scary World's video on the albino cult directed me to the ones you made about it so I've been kinda binge watching a bunch of your videos. I never heard about these albinos and a park ranger said he thinks 80-150 of them are there.
$5 ???😳
yup, $5
don't need to explain your motivation. don't need to know his.
if it's running well, you got a good bike. looks like a motorcycle, not a sci-fi fantasy, goes fast enough for all practical purposes, reliable and easy to maintain. should be a boxer in every biker's experience.
only problem is, is god gonna balance things by dropping a rock on yer head?
Dieser Kickstarter kann einen zur Verzweiflung treiben.Taugt nix.
HE SAID THE KICK START WILL DRIVE YOU TO DESPAIR ...... TRU DAT!
