Wilson,
Wow what a machine I really hope your friend is well enough to enjoy it now, it must be a very savage beast and the braking arrangement certainly sounds hairy. Still smiling about the steel plate.
Thanks for the tyre information I had no idea there was a shortage of these for the vintage boys.
A bit eye watering the price of your RSR tyres too and I was surprised at the replacement interval on your M3W I suppose that is because they are motorcycle tyres really. Good to hear Longstone have opened up out in France there are quite a few M3W owners out there now I believe.
