I am in the final stages of a K café conversion and down to the last bits. I want to swap the gas cap for a more industrial metal looking one like on the newer k1200, 1150, f650 etc. I know the newer caps have more mounting holes which I'm sure I can adapt to my K's tank.

I'm curious if any of you jolly Bricksperts know if they are the same size in circumference?
