Ta - I hadn't realised that the Evo2 tanks / fairing were so newly released - no wonder no pics yet ...

I sold the 2008 model a few weeks ago...
So far, I haven't rubbed the tire on the 2012 model, but I haven't tried to leap tall buildings yet...

690 engine stalls

A friend's 690'10 Enduro R has this weird behavior:

when closing the throttle and pulling the clutch, the idle drops so low that sometimes the engine stall... This does not happen always, sometimes the revs drop low but still it manages to keep working.

Upon some testing the idle drops but slowly (maybe the idle stepper motor) gets the revs back to normal idle.

tried loading a different map (EFI & EPT) with TuneECU, noticed the TPS value is a bit high (0,7 warm).

Cold start is normal, revs go up, then go down, only when riding if closing the gas and pulling the clutch it acts like this.

Clutch switch is disabled so the bike thinks the clutch is always pressed.

Anyone had this before?

Stock or aftermarket exhaust?

Akro exhaust.

does same thing with stock airfilter and powerparts foam filter with open ktm cover.

Loaded the Akro Evo1 map and didn't change the stall behavior. Changes noticed only at higher revs.

Aaah - the slip-on is the original cause. The less restrictive pipe doesn't give enough back pressure.

I had a similar problem on mine. The PO had installed a FMF Q4, but not remapped. If I removed the baffle/spark arrestor from the Q4 it would stall very often as I coasted to a stop - just like what's happening to your buddy.

First step should be loading those Akro maps, both of them back to the bike.
*YOU MUST* do both the throttle position reset and the idle reset procedures when you load a new map suite. Failing to do so, especially the idle reset will result in a whole lot of ZERO change. So ensure that the Akro map is being correctly uploaded to the bike and then the proper resets are being done

If you're feeling more industrious some folks at SMJ did some real testing and data logging
http://www.supermotojunkie.com/showt...s-with-TuneECU

I'm running an EVO1 lid with K&N type filter at the intake and an Apex or Q4 (woods) with mappings based on the work on that thread and the bike runs like a champ.

Not trying to spoil your conclusions, but let me add more information:

Did both the throttle reset, key on, switch on, slowly go to full throttle then go back slowly, switch off, key off and then did the 15 minute idlefar away from the bike, not letting anyone touch it. Noticeable results only in the high revs with smoother and more powerfull response, weverything else remained unchanged.

I also own a 690 R with akro slip on, foam filter and open powerparts airbox cover (my friend used my bike's parts too for testing purpose to pinpoint any changes). Never had a hickup or sort of. Ran it with both db killer and without. Only difference was louder operation... Till a few weeks ago i had the stock map and zero issues, never had any stall or related to clutch stalling problem, fires instantly, engine response is great and so is fuel economy.

Loaded the akro map, only change was also in the higher revs. Everything else is almost perfect with the exception of two ocasiosn on decel the engine kept accelerating for a fraction of a second but then acted normally again.

i'll dig into SMJ too.

Hmm, the description of the problem is very consistent with the troubles folks have documented when going from the stock to aftermarket exhaust without a remapping. Hence my first line of thought.

Though it would effect the running over all - has the fuel filter been replaced? The injector cleaned?
I recently replaced by fuel filter at 4XXX miles and it was in terrible condition. Not long after I sent out the injector for a pro cleaning. When I got it back the notes stated that the plastic screen was coming apart and there was filter debris in the injector and the spray pattern before service was noted a 'poor'

With the filter an injector dirt issues these bikes are known for it might be some time for more digging in to ensure everything is right as rain.

Can't assure there was any fuel filter change, and hardly the injector was ever cleaned, however can't relate those to this specific behavior.

Engine start and idle is very consistent.

Nevertheless, we both have quite similar bikes and my buddy's bike noticeably pulls less strong than mine. It vibrates less but feels significant weaker. Final drive ratio on his (15/47) is a bit longer than mine (14/45), but from my knowledge this difference wouldn't make his bike so much weaker than mine.

First, unless your bikes are setup exactly similar I wouldn't compare them, each bike is different enough in stock trim and comparing two similar but not exact setups can cause a person to chase the wrong troubleshooting variables.


Basically we need to find the problem so lets be methodical. Did this problem appear out of the blue or after some change? Did the bike ever not stall?

Not trying to say that the filter or injector is the root cause. Just issues than could make an existing fueling issue harder to deal with.

And his final ratio should make it feel *more* grunty and powerful. One would run out of RPMs earlier but pick up more quickly. So if you two had the same final drive, his would feel further weaker.

Well it was not an exact comparison, but the fact is that there is an issue with the idling just when the throttle is cut and the clutch pulled.

The comparison between bikes engine response was related to yuu's query on fuel filter service and injector cleaning, as in fact we noticed different behavior with his bike pulling significant less.

BTW, thanks for the link in your signture, was not awar of a ktm690 info.

Agree, still it's a valid point as i'm in the auto industry and have seen quite a few problems related to injector condition.

I stand corrected on your calculation. His bike situation is worse than expected.

I have the same problem (2012 690 R), and came to a similar conclusion - not always, but occasionally - e.g. brake and clutch hard before a corner, and chuggs right down low +/- stalls - mine also resulted in a flashing oil pressure light, which persists for a while - oil pressure tested and OK.

check with your dealer as there is a brand new mapping just come out from ktm for this,
