    Somewhat erratic coolant temperature readings

    Update: Rain is finally over (we did need it though - more rain in the first 6 weeks of this year than all of 2019 combined !). Did a nice ride with my friend on his Honda Blackbird today. About 250 km thru the country-side, and the temperature stayed at around 85C all day even when pushed hard...

    Somewhat erratic coolant temperature readings

    Hello fellow FZ6 fans ! Another update: I received the radiator (the correct one this time) Its a more heavy duty, all-aluminum radiator. I actually like it better than the original one with its plastic parts. Installed the radiator. Had a few little snafu's when one of the mounting holes for...

    Somewhat erratic coolant temperature readings

    Hello follow Yamaha riders: Want to give you an update with my problem: I received a new radiator and found some time this weekend to work on the bike. Taking the old radiator out was pretty easy. After I mounted the new one I found that this radiator doesn't actually fit the bike. The mounts...

    Somewhat erratic coolant temperature readings

    Thank you for the advise. I know. I just purchased this bike used in this condition and discovered the overheating problem.

    Somewhat erratic coolant temperature readings

    Thanks for the tip. I haven't found build-up in the radiator (yet), but in the old water pump which I have removed. I think there is a chance that there is some build-up in the radiator (well, I actually hope that's the case). This would be obviously fixed when I replace the radiator with a...

    Somewhat erratic coolant temperature readings

    Hello Everybody: Here is an update. I've replaced the thermostat (yes - it can be done without removing the airbox and the throttle body !) and the waterpump. New seals etc. I flushed the coolant and replaced it with high quality motorcycle coolant 50/50 mix. The result: Nada :-( The bike...

    Somewhat erratic coolant temperature readings

    Hello, thanks for asking. No updates yet. Still waiting for the parts to arrive - they come from the U.K. (same part in Australia cost about 4 times as much !) and it takes a while to get here. Cheers, thanks for all your help and merry Christmas.

    Somewhat erratic coolant temperature readings

    OK Thanks. Good advise. I didn't know the impeller can detach from its shaft. From the diagrams (https://www.yamahapartshouse.com/oemparts/a/yam/500460e1f8700209bc7952bd/water-pump) it looks like its all one part. But I haven't taken the pump apart yet and probably will not until I have...

    Somewhat erratic coolant temperature readings

    Hello fellow riders: Just to give you an update whats happening: I have done a really good coolant flush and ran some commercial radiator cleaner / flush solution, then flushed it again with distilled water. Also emptied the overflow bottle and then refilled it all with pretty expensive Engine...

    Somewhat erratic coolant temperature readings

    Thank you. I've ordered a new radiator cap. I checked the old one and it looked o.k but its worth a try I guess. And I will flush the coolant, just in case. Does the bike just use normal 50/50 pre-mix Green Coolant ? Somebody has a link to a youtube video on how to do this ? It looks like the...

    Somewhat erratic coolant temperature readings

    Thanks guys for the replies. Yeah the behavior of the temp display was weird. It went from 124C to 102C in like 2 seconds. I assume that 102 C is actually the correct temperature (which would be expected) while the 124 was glitching ? Yesterday I've started the bike and let it idle for a while...

    Somewhat erratic coolant temperature readings

    Hello, I just bought a used 2009 FZ6-S and rode it home for about 300km. It was a very hot day (about 36 degrees C ambient) and I noticed that the coolant temperature reading kept creeping higher, slowly but steadily regardless of rpms and speed. It increased to 114 C and I heard the fan...
