Thanks so much! It will be a fun ride once completed and I cannot wait to share the process with you. He's absolutely loving it-it brings back so many good memories from his early days in Germany. Thanks for checking in! -Andreas
You got this R25 just in time. It possibly had a month or two before catastrophic failure occurred. The oil looks like it had some old STP additive in it. Have fun and keep up the good work!
I believe you are right, it was a close call! It might have been an additive like you mentioned - I'm just not sure... The fun has just started and I cannot wait to share more videos with you! Cheers
I hope you enjoy this deep dive into a motorcycle even older than my last project. Its rich patina reflects the many years it's seen. Soon, it will be revived and fully functional, ready for new adventures. Thanks for tuning in! ❤️
More great fun! I have to compliment your purposeful attitude and methods of organization. The engine mount is such a great tool. It’s so interesting to me to see these German engines torn down for rebuild and looking at what’s inside. Simple but well engineered for their era. CU soon!
I never would have guessed the Slinger - so cool how you figured that out! And OMG what was that oily slime 😅 Looking forward to more videos 👍 greetings 😉
It's sad that I don't have any history on the bikes service-life, but I suspect a good-maintenance check was long overdue! I'm glad I don't know what that was and it's not well disposed - the oil that will go back into this engine will not look like that...haha Thanks for your comment and I can't wait to share updates with you. -Andreas
Thanks Daniel! It is more simple and there are fewer parts. I find it interesting to see the older design cues they used and some older methods during manufacturing. I hope I can share many more videos about this bike :D Cheers
Those tappets can be reground. We used to have a tappet grinder where I worked and once in awhile I did a set, mostly old V-8 Ford flatheads. They should be convex when properly done, that way they ride slightly offset on the cam lobe and spin.
Did I hear that normal maintenance is an engine tear down every 3000to remove and clean the sling oil filter doo-dad? Nooooo….. I must have misunderstood what you said, I played it back twice and still don’t get the message, sorry. I am assuming it cannot be what I thought I was hearing so I ask. At around 6’ 18” -6’ 25” is where you mention “full tear down”. These are really excellent repair videos. I don’t think there are more complete and clear ones available anywhere actually. Great work.
It's rally a different approach on a modern bike. First remove the plastic, then wires and you will finally see some of the engine and gearbox haha. Thanks for pointing this out! Greetings from Canada
Another great video! 😃 I’m very much enjoying your BMW series, please keep them coming. Maybe in the future a nice old BSA or Triumph? 😉 Btw, it’s nice to see you taking the time to tear these bikes down and really get them right!
Thank you for your feedback! I’m thrilled to hear that you’re interested in longer videos. Don’t worry-I’ve got plenty more in the works😃👍🏼 Cheers Andreas
Yeahhhh.. but be honest, and admit to yourself: it is a sin to run the engine with this 70 year old(?) oil...It could have get damaged. The oil strainer is clogged...oil pressure??? Your mechanical skill is however beyond discussion. Groeten from the Netherlands.
I would say, it would be a sin unless I didn't check all the all moving components before trying to start it. Even in my last video when I checked the oil it was crystal clear and I'm still wonder how that even fooled me: ruclips.net/video/aHpINyfw9EM/видео.html (check at minute 4:03 and see for yourself). I'm not making this up haha! It could have been really bad if I ran it for any longer, so I'm very happy to take it apart and give it new life. Thank you for your concerns and comment - it's much appreciated! Greeting from Canada!
Another jewel in the making🤩 Speaking of, how's your Dad enjoying his gorgeous new ride?
Thanks so much! It will be a fun ride once completed and I cannot wait to share the process with you.
He's absolutely loving it-it brings back so many good memories from his early days in Germany. Thanks for checking in! -Andreas
@@WorkshopRebuild That's wonderful 👍😊
Fascinating, please keep this series going
Thank you, Gary! This video series does not end here. Many repairs will need to be done and I hope I can share every detail with you😊

Awesome video! Amazing! I am really enjoying this series. Best!
It's awesome to hear you're enjoying it! I'm excited to keep sharing the journey😃 Thanks for tuning in - Andreas
@ I’m curious, what is your background? Mechanical Engineer?
Amazed at your mechanical skills
I'll be glued to the screen Andreus.

A very well made video. Thank you.
Good job ! This engine seam to be more simple than the 2 flat

Good 👍 Appreciate it
Thank you! I'm glad you appreciate the effort and hopefully you enjoy a deep dive into the BMW R25😊 Regards Andreas

I love your strip downs , I would trust you as a meticulous and questioning engineer mechanic.

Pare minut i maszyna rozebrana. Współczesne motocykle to ... bardzo skomplikowane maszyny i rozebranie nawet 125 jest kłopotliwym zajęciem.

Uli has a Chain wheel for camshaft. Then it is faster
Thank you for your advice. I will take this into consideration when ordering parts, wich will happen very soon😊
Why do you have a R25/2 frame ?
According to the serial # it’s an R25/0 (1950-1951)
Another great video! 😃 I’m very much enjoying your BMW series, please keep them coming. Maybe in the future a nice old BSA or Triumph? 😉 Btw, it’s nice to see you taking the time to tear these bikes down and really get them right!
it's better to make the video longer, 20-29 min
Thank you for your feedback! I’m thrilled to hear that you’re interested in longer videos. Don’t worry-I’ve got plenty more in the works😃👍🏼 Cheers Andreas
