It's this one Rob.

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

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 ...

Bike is a 1988 R100RS with 100,000+ miles. The problem I had (and posted on here about a few years ago) was that when hot it became impossible to get neutral. To cut a long story short, as I had overhauled the gearbox I thought I had made a gearbox reassembly error. This blinded me to other causes. ...

Thanks for confirming, it's an odd sort of material like a ceramic.

Drilling is not easy at that point so I will try to find a replacement here in the UK or Europe.

On my Mono 1988 R100RS I have the kind of rear carrier specifically designed for a top box, it connects down to the pannier frames. It seems one time I over-tightened the top box because the carrier part is cracked all the way through. My question is to those of you that know about metallurgy, which...

I recently had to replace my driveshaft (97K miles and the UJ had become notchy). On reassemlby I used Hylomar Blue sparingly and so far not a trace of oil.

High five! The noise it made when if first moved was a kind of metalic groan...

I've just bought a San Jose replacement yolk (triple-clamp thingie) to fit there in the next few weeks.

It's off.

I got a breaker bar long enough to brace against the frame, and a dirty great long spanner.

When it moved, it was a nice feeling.

Well the nut moved with some heat... The single-shock bikes have a different fork. The big top nut secures onto a gold inner thread, which is a part that pushes up through the tube. This is all a long way of saying that the inner thread is spinning when I try to remove it. Clearly I am supposed to u...

Thanks guys.

I'll try heat and a soft mallet.

Does it matter where the heat is applied to? Eg, Am I heating the nut, or tube, or both?
