The clutch in this 1983 R80ST is the same as the one used in the 1983 R100RS that I rebuilt and converted to an RT model. You can see the procedure I used to remove the 1983 R100RS clutch here.
I published this document to show how I repair, refinish and paint parts on this project. It contains links to other documents as well as original material. I will be adding to it as I progress with the project.
I get a number of questions about how I achieve the “like new” patina on the engine block, transmission and rear drive. I previously published two documents on refinishing, so on this project I decided to create a short YouTube video showing the materials and tools I use and how I restore the aluminum to like new condition without bead blasting the engine block. Blasting the block requires complete disassembly and then meticulous and laborious cleaning of all the oil passages to guarantee no bits of glass are inside.
Here is the document and YouTube video I published. The document contains links to the other two documents about how I refinish various parts.
In preparation for removing the engine from the frame, I remove the top end (valve covers, heads, cylinders, wrist pin, cylinders) to reduce the weight. Although not part of the engine top end, I also removed and inspected the cam followers as it is convenient to do that now.
Ready To Remove Top End
This is not the first time I’ve done this. The 1983 R100RS motor is built the same as the 1983 R80ST motor, so the procedure I documented for the 1983 R100RS applies here as well. Rather than duplicate that procedure, here is the link to the documentation on the 1983 R100RS which contains all the details you need to complete this work.
This document will provide a brief summary of the procedure with pictures of what I found as I did this work on the R80ST engine along with a summary video of this work for the R80ST.
VIDEO: 1983 R80ST Remove Engine Top End and Cam Followers
And here is the longer video I made for the 1983 R100RS which contains additional information you may find helpful. However, I didn’t show removing the cam followers in this one.
