I had a '54 Bullet. It revved to an indicated 65mph in third. My AJS ran out of puff at 55. My '65 Crusader was supposed to be the sports version, but I have my doubts. Gander and Gray cocked up the rebuild and I got a local engineer to retro sort it. It did an indicated 70 flat out. Handled beautifully, though I didn't appreciate that till I built the AJS......
