Great site.
I grew up racing on the East Coast. First a stock ATC 70, then a fully suspended A+ Industries framed PowerRoll-build "70cc" monster, and lastly a Honda CR60 converted to a 3-wheeler that would outrun a stock 200X. I was a lucky kid with lots of great memories of my own races and riding trails around the N.E.
I also witnessed Pro racers such Marty Hart & Jimmy White battle, Sparks and Dunlap thrash 4 strokes, Jackie Meadows mop up, Rodney Gentry's Cagivia days & Honda factory ride. (Steve Wright, Steve Mendanhall, Mike Coe, Greg Baker, Timmy Helter, and Gary Denton as well).
...When those goofy 4 wheelers took over, the Pros finished their careers on 4 wheels. I threw my leg over a dirt bike and rolled the 3 wheelers into the shop.
Pictures on the way when I get them scanned.
