I need to make some corrections to questions that were asked. I am very late with the right answers but would like to make it right just the same.
The gas tank was not a Whizzer tank as I stated, but from a of long ago kit called "MX-5" which has been discontinued for some time. One comment about the gas tank looking different than perhaps being mounted in front like a motorcycle or most motorbikes. I wanted to keep it looking more like a bicycle.
The spring fork is the old Schwinn very heavy steel fork that is no longer availabe either, but there are new light weight spring forks available that look nice.
Best Regards
Bill Snow
