Running the bike at idle with the radiator cap off, so you can see the coolant...... run it until you see the coolant moving in the radiator -- that means the thermostat has opened up and all parts of the cooling system are flowing coolant. Once that happens, repeatedly squeeze each section of hose so you force a slug of coolant to change places. The routing of coolant hoses on the ZX6 always seems to include at least one section that has a n shape to it, that can trap air. Burping the system is meant to collapse that air bubble and fill that space with coolant so there are no gaps in the flow.
If the fans never turn on, but the temps read consistently, the problem may be in the wiring. On the side going back to the battery (-). This usually involves a wire bolted to the frame, and the frame then carrying the current back to the battery. That bolted together wire and the frame is a serious candidate for rust. Steel bolt, plated copper terminal, aluminum frame...... tailor made for galvanic corrosion. Add water and dirt, and you have a wet cell battery.
Take the grounds apart, and wire brush everything shiny and clean. Then, dope them with dielectric grease, and put it all back together.
Let us know if that helps.
