This is a reach-out to some of you "vintage" racers (and I'm one of you!)
Back in the late 70s, around the same time that Butler & Smith were dominating AMA Superbike, a young lady named Liz Wimmett successfully raced a BMW R90 in some northeast club events (WERA & AAMRR).
I recall her winning a `77 event at Pocono ... prob in the Junior Class.
Wonder if anyone here remembers her. Just a long shot request.
