    1983 R100RS Rebuild Project Journal

    Folks,

    As I did on my last project, rebuilding a 1973 R75/5, I'm going to post updates on my new project, rebuilding a 1983 R100RS with 83,382 miles on it.

    I just posted the first installment on my blog site, Motorcycles and Other Musings,

    • 00 BMW R100RS Pre-Project Inspection

    and started the 1983 BMW R100RS Rebuild: Project Index" project index pagewhere you can go for all the links to my procedure write-ups for this project.

    Here are a couple pictures from the "home coming" journey.

    Kurt,

    This could be interpreted in several ways ;-) What's amazzing is the effort you put into moderating this list, helping me with questions and providing great support to the Airhead community. I greatly appreciate your efforts.

    Best.

    Thanks for that...the moderator team tries to keep the "rubber side down" here so we can share our information and thoughts. But having such well documented refurbishments for others to refer to is priceless.

    From an Airhead standpoint, we could use more DIY posts (OK, how about some! ) that newbies could refer to when doing regular maintenance. So often I'm 80% done with an oil/filter change before I remember I could have documented it. Then I give myself a dope slap and leave an oil mark on my forehead. But really, more visuals would help all of us.

    In 2005 I rebuilt my 82 RS. I look forward to watching this progress and to see what I might have done better. I still have the bike and LOVE it.

    Jaguar

    Brook,

    The left-rear fender in this thread's first pic looks suspiciously like a 3.4 or 3.8 Jaguar sedan. I had an XK-150 once, the the bumper design is familiar.

    Rear Fender Assembly Removal

    I'm making progress on getting to where I can remove the electrical system. I finished taking off, and taking apart, the rear fender assembly that includes the license plate bracket with side reflectors, tail light housing, turn signals and stalk, the cowling tool box and the rear wiring sub-harness.

    You can see what I found and how I did the work here.

    Smile Tank, Seat, Fairing Removal Completed

    Folks,

    Due to the blizzard in Denver yesterday, I had time to finish up some documentation on the project so far and post it to my site. The focus has been on the fairing disassembly and a catalog of the fairing mounting hardware and where it goes. I found existing parts fiche aren't very helpful about what fasteners go where.

    Here is a link to two new publications.

    52 BMW 1983 R100RS Remove Seat and Seat Cowling
    46 BMW 1983 R100RS Remove Fairing, Dash, Volt Meter, Clock, Ignition Switch

    I included a couple videos, one of which shows details of how all the fairing panels are connected.



    Here is what the project looks like so far.

    And the stack of boxes I use to organize parts, which will grow as I get down to the frame. :-)

    I hope his is helpful.

    Best.

    I look forward to following your progress. Right off, I have two related questions.

    1) What kind of windscreen is on the bike? It looks about half the size of the one on my R80RT. It looks like there would be correspondingly less wind resistance.

    2) Regarding the carburetor rebuild, I saw that Bing sells an instructional DVD along with its rebuild kits. Does anyone think it's any good / worth the money?

    Bing DVD is excellent IMHO

    HI Tyro,

    It's the stock RS screen AFAIK. Of course, the RT upper faring is different from the RS as it's wider and so the screen will be larger than the one on the RS.

    Can't say anything about the Bing DVD. I did buy their manual that explains the operation of the constant velocity carburetors and also provides clues about how the jets interact across the RPM range to help with tuning.

    Hope that helps.

    Best.

    1983 R100RS Rebuild Project Journal

    I'm now riding my 3rd '83 R100RS. Best bike ever as far as I can tell and I've ridden a lot of different models. My first one had over 190K on it when it died of blunt force trauma (i.e. an accident). Just picked up a fully rebuilt one three months ago. The previous owner, a BMW tech, did a full restoration 10 years ago and then hardly ever rode it. I'm now going to ride the crap out of the thing.

    I look forward to reading your journal. Thanks for sharing!
