    Hi Guys

    I have a very irritating problem.

    Sometimes coming to a halt and when activating the clutch, the idle rpm drops to around 1000 rpm and the motor cuts out.

    I have Akropovic slipons and all the ¨emission¨ stuff removed and disabled in Tune Ecu. Running the 2006 akro map EU model.

    Atm the clutch switch is jumped but does not change anything.

    A couple of days ago I cleaned the throttle bodies and I thought they were the culprit, because suddenly the idle was at 14-1500 rpm and it did not act up on a 400 km trip.
    Today it did it again.
    This is very tiresome and takes away the lust for riding, sometimes you end up in some sketchy situations when the engine cuts out.
    My idle is set at 1450 in Tune Ecu.
    I also have the G2 Throttlecam installed.
    Was told by a friend riding behind me that it smells rich, could that be the problem?

    Hope someone can help

    Possible causes of those engine cutting problems:

    Sidestand switch acting up
    Ignition switch contacts dirty
    Ignition switch wire cut
    Main relay or battery connections loose
    Bad grounds

    Ok, but would that not mean that I should have problems just going down the road?
    Its only when pulling the clutch.
    It did it again tonight, the rpm goes down to around a 1000 rpm when clutch is pulled, sometimes it cuts the engine and other times it comes back to 1400 rpm after 2 seconds.

    I will check all the other stuff tomorrow but it sounds like I would have the problem more often with the problems you have described.

    Sync throttlebodies and clean the injectors, also check your gearselector sensor because the plug might be dirty.

    Now, when the rpm drops, did you try and blip the throttle to see if it stays above 1400?

    This is probably your culprit.

    Same bike, same story here.

    TPS was in range but idle would drop after an hour of driving and the motor would just die.

    Solution that worked for me: turn O2 sensors back on.

    Hi Guys. Checked lots of things today but everything looks to be within specs.
    Battery was dry though so refilled it and put it on charge. No problem starting the bike. All surfaces are nice and clean; no corroded contacs anywhere but still gave everything some dielectric grease.
    The tps reads 0.59 or 0.6 warm at 4 bars.
    The sync is good 365 vs 370 which is pretty close.
    The gear selector switch is located where? the only thing I can see near the gearselector is the switch for the sidestand.

    Havent tried activating O2 sensors yet

    Follow the wires from here: [​IMG]

    It's a black plug with a green, green-yellow and red-blue wire. The green wire is for neutral, the other 2 for first and 2nd gear. Maybe take the 2 contacts out of the plug, put some tape around them so they don't short and go for a ride. (make sure it's not raining because the connector is not sealed with the wires out!) See if the problem still persists.

    Worth a shot. :freaky

    edit: wrong about the colors, those where from my SDR. :D

    Here is the adv color code, just keep the green-blue one connected:

    Hi All

    Well today I reenabled the o2 sensors and so far no stalling. Can this be the solution? I sure hope so. The bike runs fine no dead spots. Why do some of us disable them in the first place?
    So far thx for the tip "sixdays".

    Hi guys

    So today on a short 5 km trip it stalled again, all the time. Wth is going on?

    How can so many people have exactly the same problem and KTM does not do anything about this? This is starting to bother me big time, never knowing whether or not it stalls when pulling the clutch.

    Since last I also changed the battery, since the old one was completely dry.

    Besides the stalling problem, I must say I find the difference between O2 sensor off vs on, huge. Some large bangs in the exhaust when decellerating and also more rough on the gas, however the smell of too much fuel is gone with O2's enabled. I personally prefer the O2 sensors disabled.

    If anyone has any new advice,it would be much appreciated.

    Does it do it in neutral as well or only when it's in gear? Do you experience hanging IDLE (3-4k rpm) sometimes?

    If not yet done, try reloading the map into the ecu and after that do the 15min idle trick.

    Sounds like the bike is stalling due to low rpm caused by clutch dragging
    If you roll to the lights in neutral does it still stall?
    Try that and it may eliminate or be the culprit ??? If it is u may need to shim ur push rod at the slave end

    I never have a problem with high idle when driving, but sometimes when I start the bike cold it goes up to 3/4000 rpm. I just switch it off and restart.

    Have reloaded the map today and disabled the O2 sensors, set idle at 1600 rpm and did the 15 min idle afterwards. Havent driven it yet, also checked the fuelfilters and ofcourse need a new o ring, the old one broke. Also did an oilchange.
    Checked all plugs I could find on the bike and gave them dielectric grease.
    Also did the Black Dog sidestand relocator.

    Took the throttlebodies of today. Can anyone explain what the 3 small locked screws control? They are locked with yellow paint and can only be adjusted from underneath. Can they by any chance be related to my stalling problems?
