I'm in touch with Mark Hooton of:

http://www.cymarcbikeparts.co.uk/

The idea is that he is making a prototype radiator guard for use on bikes that have had their fairing removed. This will fit on the radiator using the existing captive threads. At this stage I'm not sure what form the guard will take, whether it will enclose the sides and top fully, partially or not at all.

A donor radiator has kindly been supplied by Comberjohn (sent directly to Mark) and I've been sending him photos of how and where it mounts.

At present I'm not sure what the material will be, stainless or aluminium and we are discussing the holes. My response is that at this stage they will just be simple horizontal slots.

Mark seems to think that replicating the mild steel mesh inserts of the various fairings won't be a problem. These will be in either stainless steel or anodised black aluminium. That's a bit further down the line. I can supply him with the radiator and belly pan meshes from a K75S and the mesh from a K100RS belly pan. I may be asking for donor meshes from other fairings to use as patterns at some stage.

This is a work in progress and any input would be welcomed.

sounds great mike ...
I recon there would be a few interested folks around for this ...

I would love to contribute ...but sadly distance is an issue 

if there is something else let me know

regards

I've been working with a guy here in the US to make a one piece that's molded from the original standard K100 3 piece radiator surround so will look pretty much the same as the factory radiator surround.

However, he had a slight injury so that's on hold for a little while.

Charlie, ideas are welcome from everywhere.

What about something on the lines of the aluminium surround around the radiator of the old Honda CX500 Custom? Slight wing back at the top of the surround. Not unlike the shape of the naked K cowling
Just a thought.
I'm sure Mike could use any other ideas or opinions from the forum to help put something together.
