Hi Colin
If your Radiator is made from Nickel Silver like mine then I would just polish lightly by hand with a little metal polish as required. It soon tarnishes again but can easily be repeated and the results are very satisfying each time. The result is suberb and looks beter than chrome in my opinion. (Though maybe later bikes like yours dererve a little more chroming).
The main problem with these rads is that they are very easily damaged during fitting (and by Chromers!). Be very careful!! Also I used “thin” walled tubing, not reinforced as supplied by Jon Hodges, as it is too stiff and dificult to fit. You can get it from Autojumbles.
Good Luck!
Chris
