Thank for looking anyway, appreciate it!
I didn't get a chance today to drop in to any panel shops, but will still try to soon. I was planning on doing the same or similar thing, for the motard bike I am building up (but probably with twin radiator type coolers). So even If I have to get a big sheet I will probably find a use for most of it.
luke#92 yeah go for it, it really isn't hard to do and IMO anything to help these motors run a bit cooler can only be a good thing.
Before you go and start cutting up your number plate, I would recommend that you make up a template, buy tracing the shape of the number plate onto a thin bit of cardboard ie. an old cereal box or something similar.
That way you can cut the template how you want to sit it it place and see if it will work. If it is not good, just chuck it out and make up another one until you have something that you are happy with. Then trace the modified template onto your number plate and cut it out.
If you are keen, I think I might have my old templates around somewhere. I should be able to scan it and put it up here, so you just have to print it out, trace it on your plate and them cut it out.
