    Forgot to mention.

    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/show...-690-SMC-Ignition-amp-Fuel-tests-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. :wink:

    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.

    After a Wings exhaust install, I updated my FI map to match Beanys suggestion and have no stalling but also runs a little fat for my tastes. In TuneECU my F-L switch is set to 10,10,0,0,0,0,0,0 and the FTrim is 4%.

    Conversely, the Akro and stock map F-L Switch is 20,35,39,39,39,39,39,39 and the FTrim is 0%.

    Maybe the butterflys are closing (because of the F-L switch values) and choking the engine off???

    Probably going to FTrim at 2% very soon.

    I just picked up a 2009 690R with 8800 miles.

    It seems she was pretty much a street bike.
    She already has a Safari tank and a custom Corbin seat. (Never knew they did custom) Very comfy.
    I've already ordered in a FMF Q4.
    Next on a long list of things to be resolved is the headlight.
    What have you guys been doing about that POS BA20 bulb? I saw a note about a possible mod to put a H4 in there. Anybody know the details?

    Hey I know that bike... I'm pretty sure that was owned by a police officer in Santa Maria and was on consignment at Santa Barbara Motorsports?

    As far as the appliance lightbulb, you can change the entire headlight to the much better 2008/2012 version and get not only an H4 bulb but a much better reflector that is DOT approved to boot. I opted to change to a 7" round light but the stock 08/12 light is actually pretty good and with a bulb upgrade is totally acceptable.

    KTM part numbers for light to follow...

    headlight housing: 76514001000

    wiring harness (plugs right in): 76511079000

    mask (orange): 7650800100004

    brakeline guide: 76513025000

    I believe the misc hardware from your existing light can be reused for adjustment screws, mounting, etc. This setup should come out to ~$150

    At a similar pricepoint and light output you can get a Trailtech X2 that allows the hi/low beams to be on at the same time and the housing lends itself well to HID conversions: http://trailtech.net/ktm-x2-ds-halogen-kits.html this light is also a straight plug in to your 690

    Yup that the bike. That PO took really nice care of the bike. Lots of stuff done. Much more to do. Along with the headlight is to raise the suspension back up and put heavy springs on for my Fat Arse.:lol3
    Hmm replace the headlight assembly. Maybe so as the final product. I would like to use the existing for now. Spend my money on the other dirt stuff needed.:D

    Thank you.

    I don't think much of the TT X2. I had one that I was going to put on my 525. Not nearly as much light as the standard Baja Designs rectangle headlight. I'm not sure I could go so far as to put one of those on my new Ginger. :lol3 Been considering the big 7 or 8 inch units as well. Is yours hi/lo?

    I have an H-4 690 light and a HID 690 light That will fit in that mask
    I also have a Leo Vance rear pipe section and a Scotts Stablizer tower and a Tourtech bash plate and Disc shark fin.
    I will sell you send me a PM
    Welcome to the 690 club

    Anybody got some heavy FF springs sitting around? 90 or 100 rear and maybe 60 for the front. :ear

    Yes, I plan on getting the new spring collar before installing that rear. :D

    Could somebody with a 2009 or 2010 R please give me a length in mm on the sidestand? The PO apparently cut or replaced this one when he lowered the bike. I'll be raising it back up to full height. 2008 & 2012 shows 295 mm. I expect 09 & 10 would be longer some. The microfiche don't show for the 09. :cry
    I might do an adjustable style like I did on the 950.
