:lol:
I had to drill one and buy a slide hammer to shift it, that's after a rebuild the year before!!
I remember sending one, when I was restoring the bike, to local engineers who had to lathe the plug thin to get out the spring.
The foreman told me, the operator was banging the fork down to push out the plug and visually checked every time to see how much it moved. the last time he looked the spring wasn't there and as he looked around, the spring hit him on the head. must have shot 30 feet in the air and took a few seconds to land
best £20 I've ever spent
