Race bike count

Having just updated the number of race tracks on which I've ridden, I tought I'd take a stab at trying to record the number of different machines that I ridden on those track. It gets fuzzy when I've ridden more than one example of the same make and model. How different do thay have to be? I've ridden AJS 7Rs from 1951 through 1062, plus 7R motors in custom chassis. So inevitably this will be a bit of a rough count. Also, the year of the bike might be a bit appoximate. '70 Kawasaki F-5 Bighorn '71 Ossa Pioneer '72 Yamaha TD3 '60s?
