I just got my 1st ever ZX7R (03) on the road after a lengthy refreshening. Question I have on cooling. Do those bikes normally run extremely cold blooded? I took about a 20 mile into town yesterday in about 80 Deg heat and the coolant gauge barely moved into the range above C. When stopped at a light it started to climb up and the fan did eventually kick on but when at speed the temp gauge dropped again. I have a new radiator (aftermarket) new hoses, and a new thermostat installed. I figured if I put the thermostat in backwards it wouldn't cool at all but since this is my first Kaw I thought I'd ask the experts.
I also refinished the bike in mid 90's colors.
