I have a Gen II FZ1 (06') with 50,000 miles on it. It is running hot, with some very strange symptoms.
It will run normally and at normal temps, if left idling.... but would overheat with the temp gradually climbimg from normal to 244 as the bike is ridden at steady RPM, and would immediatly overheat if stopped at a stoplight after being ridden. What i did to address this:
- Oil change,
- Coolant flush and replacement
- New Temp Sensor (The old one was indeed faulty)
- New thermostat
After this, the bike would no longer overheat, but it was still running hot....
My bike then sprang a coolant leak.... What I did to address this:
- Replace the whole thermostat housing, including a new thermostat again,
- another coolant drain and replacement.... after which I burped the system twice to make sure there were no air pockets left....
Bike still runs hot, but now with the weird symptoms..... The bike runs fine and maintains a normal operating temp af around 188-190 in 70 deg. weather at 65MPH or below, and will not overheat at stoplights.... However, once you breach that 65MPH barrier, the bike will gradually climb to 230 while being ridden, especially if your crusing at highway speeds, and will begin overheating at stops (+244 and above).......
No leaking (oil or coolant), no frothing in the coolant, no frothing in the oil, not pushing fluid out, no weird noises, and no change in ride quality.........
I am stumped at this point...... help, please.
