Idle Adjuster Broke Off .....

  1. Any idea how to try and fix that?

    Tried to adjust idle on my 695 and the stupid thing fell off. Not talking about cold lever but actual nut that holds the throttle bodies slightly open to increase idle.

  2. The idle stop on these motors isn't supposed to be adjusted. It's set at factory and a TPS reset should sort the idle. About all you can do is stick it back on with JB Weld or a similar epoxy metal and hope for the best. Otherwise it's another throttle body.
     
  3. Derek in theory I would have to agree but...

    Stock idle when warm is 1300RPM, Cold 1500RPM. There is no need for that.

    In summer 900RPM warm is happy idle, 1100RPM cold. Sadly in winter it is bit to low so wanted to get it back to same as I had on 749s, 900SSie and carbed monster.

    Warm 1100RPM, Cold 1300RPM.

    At warm up it is quieter, much quieter at 1300RPM over 1500 RPM with termis and it actually starts dropping to warm idle after about 30 seconds.

    Sadly because of TPS you cannot drop the idle below 1300, no way I found using electronics.
    Adjusting that little dingle allows me to do that as bike is still expecting fuel and air for 1300 but throttle bodies are slightly more closed then usual.
     
  4. Hmm. I thought that the 695 had an idle control valve but it seems not. In which case, assuming you can re-attach the throttle stop screw there might be a way round it.
    As far as the broken off lug is concerned; maybe if you undo the locknut and remove the screw you can get it turning very easily in the broken off lug. Then re-attach it with JP Weld, building it up around the lug to strengthen the joint. Once it is on and had a day or 2 to set run a tap (M5?) through the threaded hole to clear any JB weld and refit the screw and locknut then carry out this procedure
    When a software TPS reset is carried out it sets wherever the throttle butterfly is as 2.3/2.5/2.7 degrees or whatever is the required for that engine. This is preset in the ECU and MUST be carried out at the closed throttle position, assuming that the throttle stop has been set correctly at the factory and not been meddled with. In your case the throttle stop will no longer be at the proper position.
    The answer is, with the diagnostic software connected, back off the the throttle stop until the indicated throttle angle stops falling. At that point reset the TPS. The software will now say it is 2.6º or whatever it should be for that ECU. Then screw in the throttle stop until it indicated double the angle on the software, in this case it would read 5.2º. Then reset the TPS again. This time it will read a true 2.6º. Now that the TPS is set correctly you can back off the throttle stop to get the desired idle speed. You would need to go through this process every time you needed to reset the TPS, hopefully not very often.
     
  5. Seems lots of hassle as it idles Ok will leave it for now
