I don’t know if it will help for your vintage of shifters. But I have a pdf bulletin for Suntour and it worked for the series on my 88 Black Lightning.

I don't have any Suntour parts, but I saved it for the "just in case" I might someday need to reference it.
I'm wondering if someone could have replaced the original shifters with Shimano compatible ones. I don't know if there's a way to ID them. SunTour thumb shifters exist.
I have wondered about that. I was going to run them because they were on the bike and y'all know my feelings about the gripshift vibe. This morning I got fed up with it and when these showed up I made an offer that was accepted. I got them for under $30 shipped to my door. Project is on hold until these arrive. A local bike friend familiar with Suntour said I'm good with these.

The shifters arrived today and are really nice but will need a bit of work to them to shift better - no biggie. They are installed along with the original Suntour brake levers and Ergon grips. I tried my regular approach to setting them up and kept running into skipping gears or not shifting at all. I need to review the Suntour info shared by @IdahoBrett and give it try again. I also swapped a shorter stem to add to my comfort. I'm so excited to get this one on the trails.

I'm interested in hearing how the first ride goes for you.
This is not forgotten nor have I disappeared.
I've somewhat unexpectedly been on the job hunt after a RIF. I've been using my new found free time I have to clean up and repair bikes that can be sold. Meanwhile, the SM1000 is waiting patiently off to the side for me to return to the project.

After wrenching on the Jamis Renegade build the SM1000 made it back on the stand. I had been suspicious about RD hanger alignment during my last dance with the Suntour XC devil and decided to look closer at the entire drive side mount. I removed the wheel, RD, RD hanger, and looked closely at the frame only to see a slight bend on the bottom side towards the tire. I grabbed a large crescent wrench, closed the jaws around the frame, and then gently adjusted it with my finely calibrated eye. Reversed the process and shifting was improved but still off. I looked at the cable routing on the RD and it was wrong so I corrected my error, grabbed the previously referenced PDF in the thread, and did some more fine tuning. Much improved but still slow to move and hanging up between gears. I opened the shifter on the bar, applied Tri-flow, and shifted through the gears while on the stand. Much better!
Time to adjust the saddle, figure out water bottle cages, and ride!
