Radiator needed in UK ++ valve clearances video

Hi all, I have a low mileage 2002 model <26,000 miles
After a mishap in workshop, I pushed it off the lift, so I removed the fairing to repair it
There is signs of severe rot on the radiator and loads of white corrosion just about everywhere, BUT there is no signs of a leak, but water level has dropped about 1" since I topped it up some months ago
So cutting to the chase, is there a serviceable radiator out there somewhere in  UK
Several for sale on internet not in UK, but they all look in a poor state

Currently I am in process of checking valve clearances engine cover is off so access to the radiator is simple

Would it help members if I made a video of the valve clearance checking and adjustment, I can't find one on YouTube

HELP

That would be great always looking forward to seeing these great videos especially those that show all the tool requirements etc
