The gauge only rose slightly in traffic and the electric fan never came on (it is about 24C today) - although I did test it with the switch on the dash, so that seems fine.
I can't help thinking the RB is running a bit rich - it is a bit lumpy at lower revs but smooths out higher. With a bike I'd be looking to fit a smaller pilot jet, but there is no option with the Pierburg. When it was off the car I noticed there was no anti-tamper cover over the CO adjustment screw at the bottom, so I wonder if someone has fiddled with it in the past. I'm tempted to try moving that adjuster in 1/8 turn at a time to see if that improves it.
Stay alert,

Ticking over in neutral?
Don't touch the mixture screw Alan!
First, check the choke control is returning all the way and the cable has some slack in it when the choke control is pushed fully home.
Next, check and if necessary, adjust the ignition timing. Despite your best efforts with the timing belt, it's possible the auxiliary shaft was a tooth out before and now it's correct, you may have slightly retarded ignition timing.
Once the ignition timing is correct, adjust the idle speed to where it should be. Then check the HBoF to see if they suggest a rudimentary method of adjusting the mixture - often this will involve backing off the idle air volume screw if fitted (as opposed to the throttle butterfly stop screw) and then adjusting the mixture for the smoothest, fastest idle and either resetting the idle speed or turning the mixture screw a little one way or t'other before resetting the idle speed.
My first thoughts would be ignition timing though.
