I'd like to see some pictures of the helix and of the surface that the helix slides on...these surfaces wear and get rough. If the helix is worn, replace it. Then carefully file the ramp surfaces on the secondary smooth, then polish with emery cloth. If the spring is worn, collapsed, or broken the symptom is the opposite of what you are having. If the main bushing is toast, the two halves of the secondary will bind.Update:
I installed a new CVTech primary clutch. Now I can clearly see that there is a problem with the secondary clutch.
The belt slips. I ordered a New bearing and a spring. The rest seems in very good condition.
Symptom: When running gears not shiffting
