Is my bike overheating? I see my headers turn red

[zoeed]

A faulty O2 sensor could cause the bike to run richer and cause more heat, it would also cause the bike you hunt at idle and while in closed loop mode as the OP described.

So a faulty sensor won't generate any fault codes?

That,s normal good to go .

Thanks for your support... This was driving me nuts...

In one of those threads and elsewhere with Google is how to sync with a length of clear vinyl tubing and a little coolant (just for color). It takes about 6-7 meters of cheap local tubing and is very easy.

So you mean I do it myself?!?!?!

I'm completely useless in repairing my bikes... I once changed the oil on my cbr600rr back in 2010... Lol... The mechanic had to retread the oil drain plug area because I tightened it too much....

I stopped doing any mechanical job on the bikes henceforth... Lesson learned

I meant that the work could be done by a mechanic in the smallest of backroad shops and done well.


The accuracy of an O2 sensor can drift and it can lead to hunting, but more commonly it usually means the engine runs rough which you have said is not a symptom. No codes till really bad.


As a couple of others have written, yours sounds fairly normal so far.

Excessively high exhaust gas temps usually indicate an air/fuel mix that is too lean, no? If this was my bike, I'd try backing out the right side airscrew on the TB 3/4 turn from bottomed and then balance the left side with the right using a manometer (homemade or shop). Might fix the stumble, too.

Yup, lean will make it run hot. Overly sensitive throttle/jerky at cruise or low speed, extreme high mileage, white-lt tan plug insulator, and excess heat all symptoms of a lean setup.

True about running lean being associated with heat. However. . .

The first step see if it IS running improperly lean. This can be done by reading the plugs, sampling the exhaust, using an IR thermometer, etc. I mentioned reading the plugs because of the remote location of the OP in Pakistan, where they may not have higher tech gizmos.

Could the quality of the fuel be an issue? I know that way back, fuel was, shall we say, not of the highest purity, that was nearly 30 years ago, so don't know about now. I do think modern big cc bikes tend to be a bit fickle...... not like the old Honda CB350 I ran around on ::025::

Roger that.. I ain't doing to it right now.. Went on a 60 mile ride today... Bike is fine on the road... It's running a bit on the hotter end... Will have coolant changed, plugs changed... Then let's see how it performs

Do you mean more than what you had previously posted? What you had posted is normal. At least the same as mine. And in the summer, and riding below somewhere around 20 mph, my fan is always cycling. Temp is always above 200 unless I get up to speed. I learned to ignore the fan when I am riding like that.

Okay, so that seems the same here too... So maybe there is nothing wrong...

I'm going crazy owning bikes in a country with no back up ::010:: ::010:: ::010::

O well... At least the Himalayans and Karakoram and hindukush are some consolation ::015::

life has moved on from the low quality fuel...

Most of the Gilgit Baltistan areas have PSO(state owned fuel company) coverage...
Btw, we all know that the s10 run fine on all types of petrol/gas... I mean I use 87RON all the time.. I used the same on my Honda cbr600rr for 50000kms and not a thing went wrong... It's still on the road btw.

You are right... I have the plugs.. Just ordered the O2 sensor eliminator from Greece on EBay by smart moto... Also ordered The flash relay from CustomLED... So I am just waiting for all the bits to arrive so that I can have them installed in one go.

Here's a request for somebody who rides tonight or who has a garage since I won't be riding soon due to our snow and ice. The origin of this thread was simply wondering if the red headers are normal so:


After your ride, simply let the bike idle for a few minutes in the dark and see if your headers are dull red near where they come out of the engine. It seems to me that I've seen it on both of my Teneres but I can't swear to it.


If using a garage with the engine running and the door shut, unscrew the door bulb so you don't let the exhaust accumulate. Obviously, open the door right away, exhaust in confined spaces is deadly, you are responsible for you doing dumb things, your wife will get pissed if you stink up the house, yada, yada . . .
