    Engine dies after slight rev up.

    Not an issue but I have discovered that if the bike is stationary, in neutral, and I rev the engine up to , say, 5000 RPM, then release the throttle, the engine doesn't just return to idle. It actually dies. Bike has 23000 kms and is a '16.  Should I worry ? Any advice would be appreciated.

    I can't say that I have ever heard of a "Tumbledown Test" ?

    You could try running the "Engine Adaption" routine
    to see if that makes any difference ...

    The procedure is :
      Ensure the engine is COLD
      WITHOUT TOUCHING THE THROTTLE, Start the engine
      and allow it to warm up until the Cooling Fan comes on.
      Leave the engine to idle for a further 12 minutes.

    Hi Coconut. Thanks for the suggestion. I'll try that. I'm no tech wizard but could you briefly explain what that will do ? To AVI.INC, was your head replaced under warranty and what was your mileage ? Thanks for both replies.

    I'm away from Home all day now so won't be able to quote
    the Service Manual description, but it basically resets the ECU
    settings for Engine Management, Idling etc.

    Hi Coconut, That's ok. No need to quote the manual number. Thanks for the reply. Much appreciated.

    I found the information in a previous post :

    Engine Adaption can ( I believe ! ) reset / calibrate / "Adapt" :

      Closed throttle position reference status
      Twist grip adaptation
      Oxygen sensor adaptation status ( off idle )
      Oxygen sensor adaptation range ( off idle )
      Oxygen sensor adaptation status ( idle )
      Oxygen sensor adaptation range ( idle )

    I had that problem service could not find it until they did a tumbledown test and the values were shot replaced head . :233:
      Spellcheck got the best of me it's a bleed down test where they check the compression ratio the exhaust valves were leaking I had to head replaced for noise at 10,000 miles that replacement didn't make any difference at all in the way the bike sounded then at my 50,000 mile service they found  The valves were shot runs great now nice and quiet glad I got that extended warranty
    I must be going too fast for too long evey time i get back i'm younger!!
