The 1983 R80ST “project bike” came with a rear fender but no front fender. A friend of mine donated a front fender for this charity rebuild project. It took awhile to get the parts back from the painter. Unlike the fenders on many other airhead models, the R80ST fenders do not have pinstripes.  Here are pictures of what I started with and what the newly painted parts look like.

Here is a link to the documentation of how I did the work, and a summary video.

This R80ST came with no right exhaust header or collector box. I decided to replace the entire exhaust system as the rear muffler and left header had a fair amount of rust.

Here is the new exhaust system installed. I’ll install the muffler heat shield when I get the side panels back from the painter.

This is a link to the documentation and a short YouTube video summary of how I do this work.

The left side crash bar on the R80ST includes a bracket for the side stand. So I start by installing the crash bars, then the side stand. Then I put the bike on the side stand and install the center stand.

Here is how I removed all those parts.

When I got the bike, it had no carburetors. I show how I remove the airbox in this write-up.

I found a useable set of used carburetors and I rebuilt the carburetors as shown here.
