Moskito,
Glad to here you're busy. I love to play with CNC equipment (and z50/ct70 motors) I try to play with the machines here at work, but the General (GE) doesn't like it when I start making things for my own personal use.
Huh, immagine that!
On the z50 and ct70 stuff.....
A while back, when I worked at a NASA facility in LA (LA as in "Lousiana", not "Los Angeles" or "lower Alabama") I used to write Technical Tips for the International Mini Bike Association (IMBA).
Not that I have any pull or anything like that, but you may want to contact Guy Foster at <http://www.swiftsite.com/minibike> and see if he is interested in selling your minibike parts on his web site. Tell him I sent you (he may remember me?)
