I have a 2003 600rr, the bike gets to 220, the fan turns on and the temperature continues to move up. Flushed the system, its now running distilled water and water wetter, it has a brand new thermostat and seal and radiator cap. I burped the system and I can't see any leaks even though I suspect I might be losing fluid. The temperatures spike way too fast. I've researched and read many post and I still can't pint point the issue. I gonna have the system pressure tested. Any advice?
