1983 BMW R100RS/RT First Engine Start

The first engine start is always a major milestone on a project. I usually perform this earlier in the build than I am on this project. But, my gas tank and the other parts that I had painted have been delayed coming back, so I’ve done everything else I can do until I got the gas tank in hand. This Friday, I picked it up and installed it.

I made a detailed check list prior to starting the engine so I wouldn’t forget something and improve the likelihood the engine will start.

Here is a link to the procedure I followed to prepare for the engine start, and how I performed the all important initial bedding in of the new piston rings with the new Nikasil coated  cylinders.

I also made a summary video of the procedure and recorded the engine start.

  1. Excellent – nicely done Brooks! Congratulations and many thanks for the thorough and very comprehensive documentation of your work to date.

    • Hi Peter,

      You’re welcome. Next up is getting the fairing installed now that I have all the parts back from painting.


  2. Congratulations Brook! Love the work you do and the great detail you show us to help when we are working on our bikes. You make a great teacher!


  3. Hi Brook,
    I bought a 1983 R100 a bad way, but the engine and electrical are normal, I would like to do my own hands-on renovation. Would you advise me what to do, how to step, as well as original parts where to buy? Thank you!

    • Hi Eric,

      It’s good to hear you are going to rebuild this bike. The materials on my site should be helpful to you.

      I don’t provide instruction to readers, but I believe the documents I’ve published will be very helpful. You will find parts at any BMW motorcycle dealer and I published a list of other resources I use in this document.

      I wish you success on your project.
