RINGA, I agree with you and am also intending to make my own because I do not like the appearance of the factory's solution to overheating.
I have made a start on my own cooling pack and I am using a pair of 140mm dia SPAL fans which will suck air from the cylinders.
I have also installed a SPA Designs dual oil pressure and oil temperature gauge so that I can keep an eye on the oil temperature.
I intend to have the fans manually switched so that when the oil temperature reaches about 100°C I can turn the fans on as required.
