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
