Note: Some riders are on list more than once because they raced for different teams or were “guest” riders, ei: Brian Pretzel on 40% of the bikes on this list.
This is an unofficial list, no backup runs, many were not at US nationally sanctioned events, engine size was not confirmed. This list should NOT be considered a source for national or world records. The genesis of this list is just a bench racing session that grew into a discussion on who ran what, who built their motors and approximately when they ran the number.
