New to GS series, Have some questions about CDI

[DYMS_GS]

Just started restoring my father in laws old GS1000, I'm new to working on bikes and decided to tackle this project to learn more about the GS Series and motorcycles in general. I'm having issues with getting spark and i think my issue is coming from the CDI. I looked into it online and found out i can just swap out the entire ignition system with an aftermarket system. my question is, should i source a used CDI which is almost impossible at this point, or should I look into a new aftermarket system. if i go with an aftermarket system what would be the most cost-effective system on the market that would work with a 78 GS1000 as i don't want to dump tooooo much money as I'm just testing things out at the moment

The 1978 GS1000 uses a points ignition. NOT electronic. Either work with that, buy/clean the points, or buy a Dyna S. There are cheaper systems, but the Dyna is not overly expensive, and it's tried and true.

BTW, GS bikes don't use a CDI. Your terminology is wrong. Check the service manual for your bike. There is much to learn...

Im not sure what this is then, part number is 374-2. Whenever i look it up it says its a CDI box for a 78 GS1000

Edit: it's the TSCU. I thought you were talking about the ignition system?

If the points look good, test the condensers. My 750 hadn't run for 35 years. I filed the points but the condenssers tested bad. Easy to troubleshoot.
