Folks,
Daren Dortin posted a podcast on his Type 247 podcast site about this project today. You can listen to it on either of these links. You can hear more about the charity, Motorcycle Relief Project, that I am going to contribute the proceeds of the auction of this bike to.
I completed the first engine start and a 10 mile break-in ride. You can see the details here.

The 1983 R80ST transmission is the same as the 1983 R100RS transmission that I rebuilt previously. So in this document, I provide links to the 1983 R100RS documents showing how I disassemble, rebuild and reassemble the transmission. I will provide pictures and details about what I find when I open up the R80ST transmission and will document any work I have to do on the R80ST that is different from the work I did on the R100RS.
I have the transmission cases vapor blasted by Colorado Vapor Blasting in Arvada, CO who is generously providing a discount to me in support of my goal of a charity auction of this R80ST to support the Motorcycle Relief Project.
Here is the link to the documentation for the transmission disassembly, rebuild and assembly including pictures of the 1983 R80ST transmission.
Here are pictures of the rebuilt transmission.

I completed this work and published a document and YouTube video showing how I do this work.

I’ve removed the airbox, transmission and clutch to gain access to the flywheel. You can see how I did that work here.
I also show how to remove the flywheel here.
I’ve published documents on removing and installing the flywheel on other projects. You can see those documents here.
Since the 1983 R80ST engine is similar in many ways to the 1983 R100RS, I will link to the 1983 R100RS documents as appropriate in this document.
Here is a short YouTube video showing how I do this work.
