New radiator and fan switch now in the 75.
Run it up to temp., no excess pressure in the hoses or expansion tank, no airlocks and the fan kicks in and out when it should.
Got a mate coming over soon, so a test run will have to be put off 'till after lunch - need to find some twisty quiet roads to bed in the pads, probably.
I have a bit of a concern that I've ballsed up the HT leads on the 2nd dizzy - I'm *sure* I checked it properly, but it won't fire up on it. Time to pull the LT leads to each coil in turn whilst the car is running to see if I have cocked it up.
2 weeks and counting 'till the next track day - I reckon the tyres have one more day in them before I need a new set. Arse.
