Since I noticed the Brake master cylinder getting very hot, I made a heat shield for the brake and clutch reservoir’s. I used some motorcycle heat shield designed for farings (the thick stuff in the below pic), and some cheaper normal silver-foil style shield.
I used a flat plate (cut out of an old computer case) that mounts to the side vent, and has a bracket that mounts round the brake reservoir with a U clamp that I bent out of an old piece of steel, and a small box section that mounts between the reservoir and plate, so the plate can by held tight by the clamp, but still a space between the plate and reservoir. Then sprayed it all black.
