Question: I know that some FF1's had the bosses drilled. The bosses are convenient as an anchor point for a steering damper (hydraulic) plate, but I had to drill mine. I've made set of steering damper plates for someone else, and he has found that both his bikes and his spare forks are all drilled 5/16". Can anyone tell me when this was done? They weren't doing it in 1950-51 judging by my own bikes.
