Long Roadholder fork length?

Can someone tell me the spring length for the Long Roadholder fork please.

Hello Roy,

Long Roadholder Springs measure 11.78",  (Sidecar Use) Long Roadholders measure 11.00", Short Roadholder springs measure 18.68" and (Sidecar Use) Short Roadholders measure 18.15", hope this helps.

Best Regards,
Karl.

Not if replaced by later longer ones. (Like mine are supposed to be?)

Am I missing something here?  I thought Long Roadholders had the two-part 'external' springs, Main Spring Part No. B2/620 and Buffer Spring Part No. B2/618.  The examples I have here measure 9.2" and 1.7" respectively.  Alan suggests these became just one spring later on - when did they do that?  It must have been from 1950-ish I guess.

Adding together my two springs gives a total length of 10.9".  I might have misr-read Karl's figures but he seems to be suggesting 11.78" as standard, so it looks as if these might be sidecar ones as they are closer to his 11.0" figure.

Hi to all- My 1950 ES 2 has one piece mainsprings-I can't say what they measure without disassembly- my   Norton spare parts list reprint for 1950 clearly shows two piece springs ( main and short buffer) in the illustration and numbers them J18 for the main and J17 for the buffer. However, when you cross reference this to the parts list itself there is only a mainspring listed -   J18 only and this is given part number E2/620. My guess is they changed to single springs for 1950 or thereabout and perhaps changed the prefix  from B to E to reflect this change - Richard

I have just rebuilt my forks using two piece springs, as one of the one piece ones that were fitted had fractured into three pieces!

Was that because you couldn't source single springs?
