Have I f***ed it?

[VNA]

Looking at the shape of the fan blades I assume that the fan runs anti-clockwise when looking at it from the back of the radiator - drawing air towards the engine. Would some kind person please check theirs and let me know if that's correct?

When the fan runs it should suck cold air through the radiator.  You don't want it to blow hot air from around the engine through the radiator. 
I'd just check with a bit of paper.  Wait till the fan runs and it should suck a piece of paper onto the rad - or blow it towards the engine from the back of the fan.

I'd go oot tae the garage and double check for you bud, but I'm a bit sore tonight, my kidney stent is playing up again. Though I'm getting it out tomorrow - happy days .

Anyway looks like you've got it sorted.  I figure the bike will be fine - I doubt very much that you've cooked it.
