William, please don’t ever retire. Your encyclopedic knowledge of motorcycle is invaluable. Thank you for sharing your talents.
Dear William, That's a really great story you're telling. I watch your videos from Frankfurt/Germany. Today, at 57 years old, I can make the unfulfilled dreams of youth come true.
With 18, there was the R80G/s just 2 years, I could make my class 1 driver's license on the orange seat. Since I had of course no money for a BMW, a CX500 had to hold out. 2020,
I finally bought my R100Gs (1990) 2020.
I have always been a screwdriver and have done many things myself and also always trusted me a lot. But only animated by your videos series, I have taken all my courage together
to dismantled the old lady step-by-step. I am currently rebuilding it so that I can go to Corsica in June.
My sincere thanks for letting me share your experience.
Unfortunately, there is nothing comparable in the land of the Boxer.
Have fun
Hilmar
next project will be a 1976 R60/7 .... ;-)
These videos are probably the best service tutorials on the internet. What an excellent resource. Thanks so much!
Wow, thanks!
Never has there been such a well thought out and complete video tutorial series on these old classic bikes. There are so many written resources that are so disjointed and hard to read and interpret, but in this era of video you are at the forefront of where the rest of the excellent sources of information need to be. These videos will be viewed for decades and will become THE reference for how to get it right.
Hello Frank , Glad you think so and I really appreciate you watching. We got more on the way.
What a lovely day it is when B2V stops by.
Glad you like it !
Bravo! meccanico raffinato, assemblaggio di grande precisione.
Kudos to everyone involved. Great presentation, lighting, sound, video. A top quality production.
Thank you! Have always wanted to see how these Siebenrock kits are installed.
You bet!
Excellent tuition William,simple and precise directions,a pleasure to watch.Marko R100CS Australia
Thank you for this latest, excellent demonstration, William. I learn something new each time I tune in.
Great to hear. Thanks for watching.
Loved this episode William, so informative. If only the current BMW range used some of the quality metals and materials of this era. When I look at the current liquid head boxer, I cringe at what the engineers have done to the brand. Everyone seems on a cost cutting race to the bottom nowadays.The forthcoming end of the internal combustion engine will be a sad day for many. We need you to provide more of your high quality channel. Thank you.
Thanks and we are working on more now ! thanks for watching !
Excellent information and very informative. Thanks for creating these videos.
I'm getting really excited and can't hardly wait to see it run! Thank you again William, great videos and a great store you have!
Hope you enjoy it!
Excellent travail , toujours au top . merci Monsieur pour le partage et a bientôt pour d'autres vidéos .
Thanks !
Very enjoyable and informative as usual, Brilliant.
It’s great watching your videos, keep it up.
Glad you like them!
Fantastic as ever, really enjoy these videos and such a help for the restorations I am doing
Great to hear!
Very good with a Lot of Details .
Thanks
Very,very well explained.
'83 R80RT... went to Siebenrock 1000cc conversion; R80 heads machined for improved "squish zone" (and a wee bit compression ratio boost) + dual plugging, kept original carbs (re-jetting no big deal..), Installed shrink tube trick to limit "Bean Can" Advance... ditched the RT snow plow.... while no R100 heads for full-blown top speed... the mid-band torque is a wet dream... she devours switchbacks with an insatiable appetite (few can keep up on the Bundesstrasse B242 (Harzgebirge... Halle > Clausthal-Zellerfeld)... might rebuild as RS...
👏👏Great!
Thanks very much I would like to send my r100 heads your direction for service. That is going to be a very pretty engine
Wow!!! ❤
slight tilt to carbs: levels when rear suspension loaded.
Excellent presentation and fastidious work! One question about the wrist pin bearing in the connecting rod. I had the impression that those were reamed after installing in the rod to fit the wrist pin. With new piston and wrist pin, how do you verify the bearing fit?
Great. Thanks so much.
You are welcome!
Hi guys. Thank you so much for the video series. You guys are the best! Question for you. I have a 1969 R50 conversion with an R65 engine. I am considering the Siebenrock Power Kit but am wondering if that will cause any problems with the original 1969 R50 final drive unit? Will the R65 engine with the Siebenrock Power Kit overpower the final drive?
The torque for the cylinder studs has a third step. First 15 NM, then 25 and then 35-39. I am afraid you misse the third step in the video. Otherwise exellent, as always.

Thanks for mentioning that. It may have been omitted in the editing, not sure what happened.
Do you know if the old GS800 has the same base (cranck, gearbox, etc.) as the GS1000?
No gapping on the piston rings?
Another great video William. I see a lot of bikes fitted with the metal spark plug caps. Are the black rubber?/plastic? caps that would originally have been fitted to these bikes (certainly in the UK) still available?
Hello Kevin , Check these out . They are pretty much the same as the BMW original. www.boxer2valve.com/spark-plug-connector-cap-beru.html
Great tutorial guys!!! I love your videos. I have a noise issue with my little BMW R45 from 1981. I took the right cylinder out and found the culprit. I checked the “clearance” by just moving the connecting rod from side to side (axial play) and I have also checked the radial play. It seems like the connecting rod has to much axial play. It also felt like the connecting rod could slightly tip from side to side. I’m going to buy new connecting rod bearings. What school do check next bevor I install the new bearings?
Best Wisches and and greetings from Germany, Berlin.
The main thing is to check the old bearings and see what kind of wear they have. Check the crankshaft and make sure that there is no scoring or damage. If there is, then the bearings will wear out soon again.
Hi William, my compliments for this amazing job!! I have a question for you...can you recommend me an equivalent product of gasgacinch? Here in Italy is very hard to find! Thank you in advice 😉
Hello, William! Please tell me how far the studs protrude from the engine (if possible in millimeters)? Thank you in advance for your response!
8:58 what is the Allen plug to the left of the exhaust port for
"Lightly oil cylinders and skirt of piston". Why do the rings not need "light oiling?" Thanks in advance.
Thanks for the breakdown. So I'm interested in the kit to give my R45 some more power, but do I need to replace my carbs as well? I currently have 64/26/201 & 202. Would I just need to change the jets or needles? thanks
Great job William! I had to chuckle when you put on your “super-duper glasses” googles. Isn’t is amazing how much shorter our arms become as the years pass?
It has always been my practice to put a little dab of dielectric grease inside the rubber boots of spark plug leads to keep water out - do you not do this?
So true!
did i miss the part about the o-rings for the rocker shaft oil feed
no need to check ring gap?
FWIW; "oil cooler version' (with thermostat)... GSPD has not thermostat.
Fuel line balance tube?
How much is the torque of the head cylinder?(3 stages) Thanks and great videos !
On the models that we are working on, the 3 stages are 15, 25 and 35 NM. Thanks for watching !
Valve cover studs; too far in: not enough thread for nut+washer... not in far enough: can't get nut over end of stud
The oil won’t wash the LM48 off the rocker lifters?
Yes, the LM48 will mix with the oil and eventually wash off of the parts.
boxer2valve BMW Restoration and Parts Supplier got you... thanks for that!
How many miles were on this bike before the rebuild?
The R80 had about 70K miles.
This reconditioning started with a 1981 but now it is a 1985?
Its always been a 1985 R80, just some of the work shown in some videos also applies to 81-84 airheads.
@@boxer2valve i just looked at the playlist about the current bike and two videos are named 1981 and the others are 1985. No problem just wondered if that was a typo.
@@boxer2valve the playlist is also named "BMW 81 on Reconditioning"
Your not young anymore
