So I finally got some mix made up, pulled the cover off it, and topped off the KX5 to ride to work. Granted it has been a while since I rode it... I fired it up and took a quick look at the lower right of the VaporTech gauge (1st clue) after it was running for a bit and it was pretty stable at 165. I did not have my glasses on (second clue) at the time.
Hit the freeway and noticed the 'temp' was climbing some but not to worried as it is 75 degrees out. Still climbing as I am running along steady at 65 which concerns me as it is over 200 now.
The only time it has been that hot before is when I topped it out. Coming up on my exit and it is showing 240
but it is still running happy as a clam and no pinging or acting 'hot' (third clue) but now I am worried and having thoughts of an engine rebuild and disasters. Got to make work though so keep going.
The temp is still climbing but very slowly (fourth clue) which is odd as I am maneuvering through 'town' traffic. I am thinking "Maybe I should stop and let it cool off" but it is still running fine and there is no water coming from the overflow. I pull into work and it is showing 280. Holy crap!
I kill it, get off and feel the cylinder (I can touch it) and watch the overflow. Nothing (fifth clue).
I have some free time for the first half of shift so I am franticly searching KXRiders and other sites for the highest running temps people have seen. This is just not good!
On lunch I move the bike over where I can lean it over a bit to burp the head. The movement activates the VaporTech gauge. I put my glasses on to see and burp the head. It is just fluid, no air. I check the plug to make sure it is tight (for good measure) and pop the radiator cap. Full. I stand up full of concern and notice the VaporTech gauge is still reading 280, but there is a 'dot' after the "8". Then it dawns on me. I was watching the odometer! Good Grief. Then I remember the second push of the 'mode' button gets water (head) temp. I was pissed (at myself) and relieved at the same time.
I am just glad I left my phone at home today or I would have been posting about the 'uber high' temperatures I was seeing. This is bad enough! While funny after, it was a rough four hours. Temp was fine and stable on the way home...
