I'm building a 1275 bored out stage 1001 (
) and I just got to the fitting of the radiator and fan.
I had purchased a 6 blade fan from Mini Spares but it seems to be VERY tight in the cowling. When it turns it scrapes along the cowling.
I also had to purchase a new thin spacer as the original thick one meant that the 6 blade fan couldn't fit between the water pump and the radiator...yes and it does make a mess of the copper radiator fins!
The old plastic one seems to have a few marks on it indicating that it is tight as well.
But the plastic one also seems to be marginally smaller than the 6 blade one (or possibly just an illusion).
Anybody else had issues with these and what's the solution [apart from going back to the plastic one]?
