I have an 03 YZ 450 and it blows radiator fluid out of a small hole above the exhaust(Brake side). The hole is about the diameter of your little finger. At first I thought it was a radiator leak and after the bike cooled I noticed a small drip from that hole in the cylinder. The fluid never ran down the cylinder and was burned off by the exhaust and what didn't burn was misted into the radiator on the right side (side with the cap). Please help.
