No idle and high idle problem

[Dogdaze]

Hey Ramseybella, sorry to see that you are still having a sh*t time of it. I know your financial circumstances don't allow it, but I would ditch it as soon as it becomes financially viable.
As to your question, it could be over fuelling so flooding the bike while running and ecu not leaning it out...... just a thought.

If that ain't some lame shit? ::007::
Yesterday and the day before bike went mad hatter again, rev. stall rpm's bouncing just sitting at idle.
My next question any of you folks experience an extreme raw fuel odor when you park the bike in the garage after this happens.
I have noticed this a few times and also noticed this odor when it didn't give me a hard time the next day i took the bike out it would give me a bad day.
And all my fuel lines are good and vent lines are open.

Sucks that you are still having problems. Specifically answering your question, I did have the fuel odor develop on the Gen1, which was like yours. When I tear into the bikes in the winter I clean the injectors and that stopped the fuel smell. I also had to use the following technique for the KTM 690 a few weeks ago after it'd been sitting.


To clean the injectors, I take them and the spark plugs out. Soak the injectors for at least 15-20 minutes in mass airflow (MAF) spray, because I know it is safe for plastic and electrical parts. I'll then hook them up backward to a piece of fuel hose coming from the pump, and hit the starter to motor the engine and run the fuel pump. Soak the injector for at least another 10 minutes, flip the injector around on the fuel hose, and do it from the normal side. The injectors always seem to spritz a nice pattern on a paper towel after a few times on each side like this.

Funny thing is, it only happens sometimes before the problem but mainly right after it's gone through it's fits for the day.. The days it runs fine I get no raw fuel smell at all.
I mean this is strong to the point I open the garage for about two hours, till it settles down. But I checked with a flash light and see no wetness at all, underneath in the exhaust or around the frame.. I also checked the fuel tank hoses as well as the vents. It is about close to valve check time 70k will be on my bike by the end of the day.

Just a thought...
I don't know if the S10 uses the same thermocouple that show ambient temp., and to "adjust" the fueling...but have you ever noticed some crazy ambient temp.?

I have noticed a problem with mine that may be related to this topic. Sometimes when downshifting when I blip the throttle the engine gasps and does not rev. On my last ride the engine quit when I blipped the throttle downshifting for the first time. I just let out the clutch and it restarted. It is almost like it is too lean and won't take a sudden throttle input. It makes me wonder if it is related to the cool temperatures being so close to winter. It is parked now so I have to wait until spring to see what happens as things warm up.

So I got my bike back friday (10.20.2017) from the dealer. They said they cleaned and tested the clutch switch and since then no issues. They did do as I asked and put my old ECU back into the bike, and they did a few test rides with no issues, so they concluded that my ecu infact was not defective (as I kept saying all along...) so I was not charged for the new ecu. I rode the bike home and it ran just fine as it should. I have not had a chance to test anymore since I got it home. I am hoping the issue is now resolved. They put on almost 400 miles on the bike with all the testing they had been doing so atleast I know they were in fact testing each fix they tried.

Thats exactly what I was having issues with. It just suddenly dies but will start back up when popping out the clutch, but will continue to die if I pull in the clutch until I turn it off fully and turn back on.

Interesting....strange that a clutch switch could have anything to do with killing the engine when the sidestand is up and you are riding at over 30 mph. I wonder what the relationship is or did they accidentally fix something like a loose connection elsewhere without realizing it.

As i understand it from reading on here, there is another programming mode the bike goes into when the clutch level is pulled in, and if there was a bad reading from the connection / switch then maybe the signal to the ecu was out of spec and thats what caused the issue. This is just an educated guess from all the info I have gathered. Checkswrecks had the same trouble shooting idea here - http://www.yamahasupertenere.com/index.php?topic=2895.150

Now we do not know if it is fully fixed, i need to ride it more. The problem I had was intermittent and would come and go. I have not ridden it enough to know if it is fixed. The issue would also arise shortly after taking off on the bike. I never had an issue after 5 minutes of riding, the problem always popped up within 5 minutes of taking off.

Something else to add to this pot of Soup.. ???
I may have mentioned this awhile back, this is for the folks that run at high idle 3k rpm ramp up or when it's at below 1k ready to die.
Try switching from S to T or T to S see if you can? Mine can't. Yesterday was not fun this is getting tiresome.
I am conjuring up cash to get the Ōkina shigoto done, valves checked, Plugs that clutch pressure plate noise that's been going on, air filter maybe change some vacuum lines and caps, clean some connectors.
And the MAP sensor maybe? Oh and another set of tires.
Anyway of checking the electrical integrity of the coils while they are out?

 

[Nikolajsen]

It won't switch between the modes, if the trotttle isn't all the way back.
That indicate that the "control" have given the engine trottle, and know that...
Now the question is why does it give throttle?

I don't think it have anything to do with the RPM, because you can change modes when you, for an excampel, is going downhill and in gear and RPM is high because of downhill.
In other words, you can change modes even if RPM is 5000 RPM (or any other number), the trottle just have to be all the way back.

(now without some of all the typing error, and bad spelling )

 

[Checkswrecks]

Interesting clue, and as our Norwegian friend mentions, it could possibly be related. It also could be totally unrelated for the original problem, but adding a layer.


Have you ever done a full re-rig of the throttle system? Position sensor, slack, switches, etc. It certainly can't hurt.

 

[Ramseybella]

Well I may have found a saint in the south west that has been looking into the problem with the Ten..
Bobby J's Yamaha in Albuquerque has convinced the district rep to replace my main wiring harness under Warranty.. ::024::
What that exactly means i will find out this week rep want's photos taken of my bike to make sure it's not a beaten up POS, time to get out the tooth brush tomorrow.
Service manager knows my extended warranty ran out this year and I am the second owner he just tells me the district rep knows that so lets get it done// O
He has brought the reps attention to this forum and us generation one owners having the same issue as well.
I will ether awake from a dream or i will pinch myself if this is going to happen.. Pray for me guys, and rest assure if this takes care of the issue I will continue to lean on this service manager to have Yamadog get on the stick with our problem..
This has been a shit year for me well last three years since my lay off maybe it will end on a good note?

 

[Checkswrecks]

Hoping for you.
While they are in there, consider asking them to clean the injectors and re-rig the throttle system with the positioned, switch, etc. It'll be on your dime but increase the odds of this being a success.

 

[Ramseybella]

Clean the bike Sunday head down Tuesday for a photo shoot..
I will talk to the service manager about the throttle bodies.

 

[Ramseybella]

Took it down today for the photo shoot service manager says it looked great.
I did a little detailed chat to find out what is the plan. He told me he can't say much as they can't give out to much info to the customer..
It's a Yamaha Corporate thing so I don't spill beans, supposedly they are reading the forums ours and AVD.. I am hoping this is true.
But something is going on and going to happen that's all I know at this point.
IT did act up this morning 3k high idle down the street pull the clutch in and drops to normal idle, let go and jumped back to 3k.
Stalled once then it sat for 20 minutes and all was normal the 185 mile round trip. yeah it's that far.

 

[Super08]

The last time I rode mine before I put it away for the winter it felt like the throttle stuck as I was slowing for a red light. I had to come down on the brakes and grab the clutch and then it seemed fine. Now I am wondering if this is related to the problem I have with the engine quitting when I pull in the clutch to downshift sometimes.

Any time I have had an issue with "Throttle Stuck" it was after having to start the bike with the throttle cracked open. If you started the bike without throttle cracked open and it seemed to have a sticky feeling, make sure you have proper amount of free play in your throttle cable, just a thought.

Be curious what they find out. Hopefully they can get something straightened out. I have only ridden my bike once since I got it back, but so far no issues, but in my experience with it, it was a problem that came and went with no real indication it would die until it just died.

 

[Ramseybella]

It started out rough the morning I went down to Bobby J's after about 20 minutes it rode like a champ all the way down and all the way back..
Next morning it went nuts, high idle bouncing around and cutting out over a dozen times, riding down the highway turning the key off and on feathering the throttle at intersections
so I won't get caught stalled at green. This went on for almost an hour then it just straightened itself out..
I think we all have the same symptoms just intermittent and unpredictable what it will do, high idle, stall bounce around idle..
That's why I started a head count Generation one specifically on this issue, i wanted to print it out and bring it to the techs when they start examining my bike.
A few of you replied others just boasted my problem was solved, "I bought a 2014"..
Not trying to be a dick but it needs to be out in front of Yamaha's face.. I guess their theory is it will be outdated and traded in so why worry.. That's a bad way to look at it. ::007::

I am on an un-flashed 2014ES without any issues, but I have wondered if these issues could be connected with a bad flashing job. Has anybody polled folks with these issues if they did something to their bikes that may have caused this?

Good thought but we have a number of Gen1 owners with the problem who had not had their ECU flashed.
