242 Degrees!!!!!!!

Okay, so over the winter I changed the coolant, burped it numerous times and all is well until my last two rides. The rides go well but on my way home or pulling into work the temp hit 240 both times. I didn't hear the fan so I'm assuming that is the reason. This bike doesn't like anything below 40 mph in regards to cooling.

Any suggestions on what to check in regards to the fan? Fuse? Connections? Is this relatively common?

I'm ruling out the air in the cooling system because if that was the case it would get really hot really fast. I can let my bike idle in the morning to warm up for 10-15 minutes and it only gets to 130-150 and stays cool at any speed above 40mph. It's below 40mph (stop and go traffic) that it gets hot and even then it takes a good 15 minutes.

 

Thanks for the tips. I guess I'll be tinkering with the ole VFR this weekend.

 

I had mentioned recently in another thread that at one point my fan just got 'stuck' My temp creaped up to 248 before I shut her down.

Don't know if it was debris, dust or whatever. But since it couldn't spin freely, it would pop the fuse. Once I manually turned the fan (and it wasn't that much pressure, but enough to determine the fan was definitely stuck), changed the fuse, and no more issues.

I know that doesn't address your problems, but I guess if you're going over the cooling system in general, takes all of 2 seconds to make sure your fan isn't stuck.

 

Weird... it's almost like you have the symptoms of a stuck-open thermostat, as well as a stuck-closed thermostat. Perhaps it's on it's way to permanently being one of the two. Or, your fan may need some attention.

I just did the thermostat on my 6th gen - it's not "hard" but it is tedious and frustrating at points. That being said, there is no reason why anyone with a basic knowledge of "righty tighty lefty loosey" shouldn't be able to perform this maintenance.

Here is a link to my write up, which in turn links to Action's post. Seems we both took different pictures throughout the process, but between both of the writeups you can git 'r done!

And grab a copy of the service manual if you don't have one already.

 

Thanks again all. I'm hoping it's just a stuck fan. Start with the easy and work from there. It was fine on the way home, never rose above 216 even in traffic. I'll be sure to post any fixes or found issues.

 

Not sure if I have an issue or not. Didn't want to start a new thread and being its coolant related I just gonna post problem here...

So a month ago whhen it as still freezing here in northeast ohio I started the bike with no issues. Let her run for about 25 minutes
before sgutting her down. 3 weeks later I go start her again but the battery was dead, no biggie. Pulled her out so i could jump her and thats
when I noticed a puddle of coolant on the ground and on the fairing. I checked the level and seemed a bit low but still in range. Today was
the first day above 75 and I took her out for a nice long ride, (much needed therapy), all was good but towards the end she was running about
25 degrees hotter than normal. Usually around 184 but today was a 207. The fan didn't kick on and she would go up and come down depending
if I was at a light or not. Which is normal but not in that high of a range.
Anything to worry about?

 

What is the range that the fan should come on? During the winter I had the wiring recall and I replaced my t-stat. I noticed today that the fan did not come on until 225 deg. I know last summer it came on at 205 or 210. What had happened? Any thoughts? The GA heat today was 90 deg.

 

Hmmm... mine has always come on at 230ish :unsure:
