Running hot - June 28, 2011, 10:21 PM

I have a post on the zx10 forum.Just want some fresh ideas.

Currently got a 04 zx10 from AK full micron exhaust PCIII and filter with custom tune (tuned by shop) had no problems until a few weeks ago when it starting getting hot out...

I was downtown bmore and noticed my baby getting hot @ the lights... got on 695 made my way back no problems nice and cool till i hit a light in eldersburg then it got hot.... its been getting up to 239-240 and blinking @ lights.

Everyone said its running lean...however a bike @ idle should not have any issues seeing as most tunes custom or not all have the same idle since its at idle..which mine does...the other thing i was told was to just add a 2nd fan...which all in all seems like a good idea...i've flushed/burped my system ran water wetter and still no difference...

ive been trying not to ride as much because its hot out and im due for brakes and a front tire anyway...but i need to get the overheating resolved first.

i was thinking possibly the thermostat or water pump.. but the thermostat is a pain in the ass to get to, and my only place to work on the bike is in marriottsville.

im open to all ideas?!?!?1 bike has a little under 11000 oil is fresh and fluids are fresh....

What process did you use to burp?

If it is getting hot when you sit still and goes back to normal when you are riding has to be the thermostat stuck open. Bikes do not have fan clutches so this is the only other possibility. Pop her open and see what the issue is. Could be air in the line, but it seems like you have covered that already.

Left cap off...started it let it get warm gave a few revs after that then turned off...i also made sure to squeeze the hoses a bit to make sure there were no air bubbles in there either.

i was having the overheating problem prior to the fluid change.

yesterday i just let it run at idle for a bit it got up to 210...then 212..then back to 210 and stayed there...with no issue..but then again it wasnt under any load or able to get hotter... i think this weekend ill get the bike torn down and check the thermostat out

Got to make sure it's hot enough to open enough the stat when you go to burp. You may just still have a some air in there. A *little* compressed air in the overflow tube on the reservoir can also help.

All you have to do is go ahead and tear the bike down now. No need to wait. Take out the TS and see if it is stuck open. No need to throw money at a problem when you can tear the bike down and see for certain.

Good luck!

Yes, but what if it is not stuck open, and it opens properly when you put it in the boiling water. Then you just bought a part that you do not need. You are throwing money at a problem.

I understand you have to do what you have to do, but this is what I would do if I had to do it.

You can also possibly repair the rad. Glad you saved yourself from parts hanging. Surprised you didn't notice steam or puddles, but a pinhole style leak can be tough to spot some times. Nice work.

If you want to rule out the tune just load a stock tune back onto it.....ride it around and see... if it doesnt work you can always load the performance tune back on!


EDIT*** I diddnt see the post about the hole in the radiator! looks like you found the issue!!
