My clutch cable broke on Tuesday. Thankfully a dealer had one in, and it arrived in time for me to fit it today. I thought I'd followed the routing of the original cable carefully, but after fitting the new one I realise that I'm unsure as to whether the cable should run above or below the bottom bracket of the radiator. As you can see, I ran it above, which gives the cable the shortest run. However, that means it's lying against the bottom part of the engine casing, and I wonder if it might get overheated there. Any thoughts?
