Hello everyone,
I took my 2007 FZ6 for a ride for the first time in about 10 days and I noticed the temp gauge running hot. Usually the fan kicks on at about, I would say, 170-180 ish (unless I'm clearly mistaken). But yesterday my fan would only kick on around 210. it would bring it back down to 190 and then stop. This is a brand new fan and when running it in diagnostics mode, it powers on and works just fine. In other words, its not the fan or the relay or fuse that is the problem here. This would lead me to think its some sort of coolant temp sensor or a thermostat that doesn't work.
BUT ALSO
I noticed that my reserve coolant reservoir was empty. I then drained the oil and it came out foamy(the bubbles were a slightly lighter hue of red than the oil itself) [don't worry, motul engine oils are for some reason red]. But there was no milkshake appearance, just bubbles. Now I have seen online that draining the oil after a ride can produce bubbles but then again, this is the first time I drained it while super hot so I am haven't done it before to be sure or not. When I remove my dipstick while the bike is running, there are NEVER any bubbles on the dipstick itself.
Do you guys believe that this could be a head gasket leak? The bike has 23k miles. I have one of those gasket leak testers that people use on cars but I wanted to come here get an opinion. Those things can be very fickle when it comes to results.
Have any of you replaced a gasket on this bike before? I would figure that its much easier than my car (boxer engine head gaskets are a nightmare) but I wanted to hear form you guys.
Anyway, thanks in advance.
