I was a chopper crazy kid in the late 60's, spending the summer with cousins in a Northern California lakeside resort town frequented by the Red & White choppers thundering through, and man, I had to have one. I cut off some 10 speeds forks - they were longer, you know - and 'compression welded' them (aka beat them on real good) over my stingray forks with a big hammer. The rake was bitchin and everybody stared when I rode my fine machine past. I was cool. Well right up until my flat-top wearing dad showed up and had a fit about how I was gonna get killed when those forks fell off, blah blah you're grounded, etc.. Then he tried to take them off, of course they wouldn't budge, the situation escalated to Coors fueled brute force, vise grips and hammers, but ultimately the hacksaw prevailed and my chopper days were over.
A couple years ago we bought one of those fat tire bikes for a pit bike, so of course I tuned it up with playing card spoke 'motors'. It fit right in with the IHRA NFC traveling circus atmosphere.
