I have a 2004 ZX-6RR. I have changed the antifreeze and there is always a white cream colored film on top of the antifreeze in the resevoir. There is also a white sedment that is at the bottom of the resevoir tank also. There was a sediment before I changed the antifreeze. When I change the oil, I don't see any signs of antifreeze in it. I want to know if anyone else has this problem with the white film. Any help would be greatly apprecated.
