Sorry I neglected this thread. I would like a billet flywheel because I'd like to take the pull start and cage off on a vertical 99cc build for a more vintage look. It's not just that the billet looks good but I don't trust the cheap china cast flywheel. I know the pull start housing might not stop everything if it explodes but it probably stops or slows the shrapnel.
I was hoping one of you west coast guys using the predators might know someone who could make and sell this, I'd buy a couple.
If I can't get a billet wheel maybe I can make a minimal cage that still works to contain the cast wheel and still use a brass rope start setup.
