We were doing that here in CanadaLand while riding doubles...
...with Justin Trudeau...
...while eating a bowl of poutine...
...up hill...
...against the wind...
...on icy roads in July...
...with moose chasing us...
...in the dark...
...while snowing heavily...
BUT SERIOUSLY FOLKS
Back in the 1970s tuning was a different creature than it is today. No conveniences of just jumping online and getting some help from a cast of a thousand goodly moped folk. No suppliers where you could just 'click to order' parts and pay for it immediately.
Lots of cobbling things together and bastardizing a moped with what ever larger engine you could find. Lots of trial and error (sadly a lot of error). Lots of visiting scrap yards to find anything made of bent tubing so perhaps you could fabricate a larger header or intake. Checking out machine shops and coops for sources of chain gears to get a couple of tooth advantage for speed. Learned a lot about NOT just hogging out ports while trying to port a cylinder.
City folks would be reworking their bikes in order to sprint from one stop sign to the next and dodge traffic, those of us out in the country went for the higher speeds at the cost of fast launching... and everyone was jealous of two speed, twisty-shifts and doubly so with variated bikes.
I dont know about the validity of the original posters speed claims, but I can tell you it was a lot of challenge but also a lot of fun 'back in the day'
