I'd probably go with 12 VDC minimum. There will be a peak voltage from a rectified AC, 8 V * 1.414 ~= 11.31 VDC.

I do like the idea of using a cap to smooth the alternator output. However, the kick starter still needs voltage for the spark ... unless it has a magneto setup.

What make and model of motorcycle? We may find enough information to figure it out.
