the spokes are actually stock silver, my lighting setup (or lack thereof) kinda distorted them. They are NOS nostalgia rims (black with red stripes).
As far as the flywheel cover goes, you really aren't going to get and water in there with it spinning at 1-12k rpms, the only area there can actually be an issue is the wire connections outside the flywheel.
That said, I've got a cover, but its still getting tuned, so its not on there yet. Pedal chain and tensioner still need to be thrown on.
I'll get my lighting figured out and get better photos so you can see the tiny red accents. I was trying to make it sleek, but not too nice.
