Question about 1990 Yamaha FZR 1000
The systems are like a car, but as they are all alloy there is not much debris that collects in the rad, so just flushing may not help, They have a thermostat, and a temp sender switch that turns on the fan,
At 21 years old there is a possibility the water pump seal is bad, if you top it up the coolant may come out a small 5mm telltale hole, on the RHS down near the crank, a rad pressure test may help locate this, but your going to have to undo a few screws and take the fairings off
