I’m going to rebuild the forks and I’m going to install the Race Tech Gold Gold Valve Cartridge Emulators.This is the first time I have used them. I’ve heard that they make a significant improvement in handling and compliance compared to a damper rod design.
The stock springs can’t be used with the cartridge emulators so I install the correct Race Tech springs based on my specifications.
You can read all the details of how I do this work here.
And this is a video summarizing the work.

I refreshed the wearable components using a fork rebuild kit I got from Tom Cutter at Rubber Chicken Racing Garage.
The damper rods have to be modified so there are six compression damping holes in the bottom of the rod. Race Tech supplies a piece of 3/4 inch PVC to make fork spring preload spacers to achieve the correct preload based on my specifications.
I repainted the fork lower sliders as they had a lot of stone chips.
Thanks for another interesting post with video!
I think there are quite a few us that would be interested in your thoughts of the upgrade when you get the bike back on the road.
I too am looking forward to what it rides like compared to the 1977 RS. I would not be surprised that I spend some time fine tuning the compression damping and spring preload.
