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 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.

Parts arrived and I installed the SRAM chain but cannot get the shifting/indexing right. This is my first dance with Suntour components and I’m questioning my decision to stick with it.im also not loving the grip shifters… at all.

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.
