Ladies and Gentlemen,
We are working with a.....
2007 Kawasaki ZX6R
Let me explain my dilemma.....
I feel like the bike is running too hot.
Symptoms...
The engine is shedding (what I feel to be) a lot more heat then it used too. almost burns my leg.
The exhaust gasses seem to be MUCH hotter
The carbon fiber exhaust is very very hot. Normally you can touch the carbon after a long ride and not burn yourself
When I get on the highway after the bike is started, it stays at 170 degrees F for a good 30 mins, all the way to work. Doesn't every really heat up to 190 (where normal should be)
But, when I stop it heats up to 225 pretty fast. The fan does turn on, but the bike temp doesn't drop much.
What I have done so far...
- Before I started noticing this problem I did try putting Water Wetter in the radiator fluid
- After I felt like the bike was running too hot, I did a radiator flush with water and refilled with new coolant. I did not run the bike with the radiator cap off, but the bike has heated and cooled numerous times now, which I would think, should burp itself naturally through the resevior.
What I'm thinking....
1. The bike is running lean and causing the engine to heat
2. The thermostat is sticking, allowing the bike to stay cool longer, and allowing the bike to heat up more
3. The head gasket could be leaking and super heated gasses escaping into the radiator fluid which makes it have less effect
4. The O2 sensor could be bad telling the bike its running rich, when its actually running lean? But the bike seems to run smooth.
5. The air filter could be clogged and causing the bike to run lean
6. The temp sensor could be reading the temperature wrong. The bike could actually be hotter then its saying it is.
Things to note:
- I need to drain the oil a bit, its a bit high right now
- I could check the plugs to see if the bike is running rich or lean
- It has been 90 degrees outside, but 10 degrees warmer then normal shouldn't make the bike any hotter?!
What are your thoughts and suggestions?
Is this really a problem?
What should I check?
What should I look for?
