Hey guys,
I need a little bit of help. I don’t know much about electricity and it’s mysterious ways, but I’ve been having an issue with my ‘81, and I’m pretty sure it’s electrical.
I found some older threads where a couple of members experienced the exact same symptoms on their TCI XSs, and apparently solved their problem with a new TCI/CDI box. The only difference is that with mine, the issue seems to come and go. It will either run fine, or well.... it won’t.

Mine is doing the exact same thing. It starts and idles perfectly, but as soon as I give it throttle...pop, pop, pop, pop. Everything just fires really slow. Both cylinders are firing. I’ve checked the compression, it’s good. The spark is good during idle, the carbs have been 100% cleaned, rebuilt, and synced diaphragms and floats are good. I checked for vacuum leaks, I checked the coil (even tested a different, functioning one). The rotor is definitely on its way out, but still charging fine. The brushes are a bit worn, but still making contact (I ordered a pair to be safe).
After everything, it has made ZERO difference. I even re-jetted the carbs and played with the (new) mixture screws a bunch. So before I go and spend 150 dollars on a CDI/TCI box that may not solve the problem, I wanted to see if anyone else has experienced this issue.
I’m kinda lost at the moment fellas. Any input or advice would be greatly appreciated.
Thanks
