Damage to top clamp from locknut - R100RS

Hi all

I'm currently replacing my steering head bearings on my 1988 R100RS, 103,000 miles. It will be the third set.

On disassembly, it's clear that the top locknut has damaged the billet top clamp upgrade a bit over the past 10 years or so, wearing a small but perceptible groove. I first thought I messed up the installation, but it looks like I didn't examining the fiche - the locknut just bolts in directly.

I would like to install a shim or washer to protect the relatively soft metal and spread the load a bit.

Is this a good idea and if so, does anyone have a uk source for that?

Thanks

It's very difficult to comment on aftermarket installations without knowing which of the available options have been used. There are several billet top yokes on the market and they don't necessarily use the same clamping arrangements. Do you know which one has been used.

It's this one Rob.

Although it's obvious in hindsight the metal is aluminum and is bound to suffer 'knock' wear.
