Was shocked to see that my rad had generated a pin-hole leak after riding to work yesterday
I took the rad guard off (Beowolf with etched Fazer) and realised that it had been rubbing on the rad as the rad paint was worn off in a small area (about a 1/2 to 2/3's of the way down towards the left of the bike) and I'm sure that caused the hole. It kind of naturally bends in the middle. A proper clean-up and araldite metal putty and she's watertight again.
So the solution to prevent this again was to add two stainless spring washers on each side of the bottom two mounts to lift the rad guard clear of the rad, coupled with two new shiny allen stainless bolts. Job done hopefully
Cheers
