Hi, I am hoping someone can give me some help with my 1931 101 restoration. The bike came to me in boxes of unidentified bits however it had been painted and forks fitted to the frame. When examining the rockers I noticed that the ends of the fork bell crank side studs had been sawn off just behind the hole where the split pin goes. I fitted the wheel and it looks as if this has been done because of a clearance issue. This rang some warning bells but I hoped possibly the side studs were from another model and the correct studs would resolve the issue. I ordered two new ones from Walker machine however it turned out that the diameter of the stud was different to that which was in place and thus did not fit through the rocker. Obviously something is wrong, I hope it is just the rocker but fear it may be the forks also. I measured the forks and these are about 26" in length with a distance of 7 3/8" between the inside of the forks. Also the length of the side stud seems to be the same on both new and old studs.

So are the rocker wrong or the forks also?

Thanks

Hi Mike, thanks for the reply. Using your measurements I checked my forks and they seem to be the correct length, the gap, on closer measurement, is about 7 5/16"s so sounds about right (?).

I measured he distance between the bottom of the boss of the brake anchor pin to the to of the hole at the bottom of the forks at roughly 6 3/4" - does that sound right?

I have checked pictures where I can and the rockers seem to be on the right way but as the rocker studs from Walker machine don't fit I am thinking the rockers must be the wrong ones.- is this possible, i.e. do rockers from other years fit?

Comparison of the rocker studs one shows that on the new one, the machined shoulder with the flats on it is about 1/16" shorter which may resolve the clearance issue as it would move the side stud outwards by 1/16" on each side.

I am thinking that I could get the new side studs machined down to fit the existing rockers although I would rather get things correct so do you know if anyone  is reproducing the rockers?

Finally if you don't mind sending me a photo of your rockers in situ I can at least confirm mine are on the right way. My email address is

You said you increased the clearance on your bike, how did you achieve that?

If anyone else is reading this and has a pair of rockers for sale then please let me know.

Hi Carl-Eric, yes that occurred to me this evening also The rockers are back on the bike at present but I will get them  off at the weekend and have a look.
