I hear what you say.

Does anyone have any experience of these from Legend Motorcycles?

Another question. The mudguards – apart from the holes in the rear – and the chain guard clean up to an acceptable, for now, level. I’ve got most of the surface rust off using vinegar and a scotch pad.

If I could stop the flash rust turning them brown within 30 mins, I’d be content to use them. A coat of WD40 works to a point, but would obviously wash off. Anyone know of anything a bit more permanent?

Incidentally, I contacted IKON Suspension in USA – I got a great service from them when replacing my 750 suspension – and Nils there told me that spares for the 76 series Konis, predecessor to the 1076,  are not available. So it seems I need new shocks; the bump stop disintegrated completely when I was dismantling it.  :(

Has no-one any ideas on how to stop flash rusting on what’s left of the chrome on my mud and chain guards?

Wipe the chrome over with an oily rag.

Not sure if my solution helps-but it was cheap and has worked:
A right mess of camshaft tensioner thread on outer casing.
So I tapped a new thread M8 dropped a ball bearing in crewed in bolt with lock nut-So now it’s more a manual adjustment but worked fine.
Hope this idea helps-you have nothing to lose trying it before you spend hundreds/new cases.
