Life is like a roll of toilet paper; the closer it gets to the end, the faster
it goes.

Most 70's era street bikes would run from the 12V battery supply so you would
have to buy a kit suitable for this power supply. I don't know where you are
but
here is one kit http://www.jaycar.com.au/productView.asp?ID=KC5442

If your bike doesn't have a battery which is chaarged from an
alternator/generator then it will probably use an generator supply winding to
produce the input voltage. In this case a simpler kit can be used

Here's a link to the Delta Mark 10 CDI.

I used to have a couple of these units back in the day... sure saved points and
plugs after I installed them. Never had a moment's trouble from either of
them... built both from kits.
