Fork confusion

Postby OldChuffer » Thu Jan 30, 2020 3:10 pm

My 1963 Model 14 CSR has domed fork nuts with an Allen key centre. They are corroded and i'd like to replace them but i am struggling to find any.
I'm told that the forks should be 1 1/4in with 1in diameter threads on the top nuts. I cant get to the fork diameter easily but my existing fork nut diameter is 15/16in so i'm thinking my forks are 1 1/8in. I thought the 1 1/8in forks had hex nuts and were earlier than 1963.

So, can anyone tell me if i can get domed fork nuts with 15/16in diameter threads? Any help would be appreciated.

The forks should be 1 1/8th and hex top nut. If they are domed I have to assume that they top and bottom yolks have been swapped to accommodate the hex head top. 1 1/8th forks were used in H/W models up to 54 and in all 350 L/W's and 250 CSR L/W's.

Many thanks for that. I try and find some hex top nuts to fit.
