I need the point cam part for my project. Does any place sale it?

Probably already considered, but will suggest possibility of replacing the points ignition with Dyna-S electronic ignition, which includes a rotor that replaces the points cam.

Dyna-S from Z1E

Trusting someone else to have a better answer to your specific question about finding a points cam.

Good Luck!

I think it's the timing advancer your looking for.
Ebay or some of the members here or on www.kz650.info/ may be able to help locating one.
