Gemini 50

#1
2 questions regarding a Gemini sst 50, anyone know the following...

1- How does the botom chrome part of the front forks separate from the top painted part?

2- How does the rotary valve disc come off the crankshaft?

The chrome collar that the top of the dust boot slips over is threaded. I take a rubber strap wrench and un-screw them. They have a very fine thread.
