I'm having a issue with it not have any power and it keeps dying. I rebuilt the carbs and it starts right up but when I rev it up it dies. I also noticed that it looks like one if the cylinders is not even doing anything. The cylinder is clean. It was rode last summer. I've attached a pic of the cylinders. Does anyone have any ideas?

Thanks

Have you checked if you have spark on your clean cylinder?
When it was used last year was power normal?

Definitely looks like it’s not sparking on that cylinder which explains your loss of power

I found a broken wire at my voltage regulator on my 900 STS. It was one of the red wires going to the regulator connector. Anyone know if the two red wires go to same terminal?
