    New head assembly

    I think this issue is new but may have been discussed before, if so sorry.   I had the new head assembly installed on my 2013 TTSE a week ago and it is quieter.   When picking up the bike and looking at the service report I noticed that the tech/mechanic stated that he updated the the ecm with the "retune".   OK fine and dandy except now when cruising along and opening the throttle it sounds like it is just sucking air.   The bike will pick but it seems rather slow to do so.   If you leave off the throttle a little it will pick much faster.   Called the dealer and they said bring it in and they will check the "retune" maybe it did not download correctly.    I informed them that I have been using, here we go again, 87 octane and was told that all or most new tunes are set for 91 octane but did say that it would not make the difference that I am describing.   Not lugging the motor either, it happens even in excess of 4 to 5000 RPMs.  So anyone else have this issue or has it been discussed? 

    Thanks

    Without entering the fuel octane debate again,
    just use whatever it says in your Owners Handbook,
    and you won't go far wrong.

    I'd be surprised if an updated Tune made that much of a noticeable difference.
    ( I have been surprised before though ! )

    If have heard of Throttle bodies not being refitted properly,
    allowing air to be sucked in, and this just might be what you are experiencing,
    so when you take the bike back in, ask them to double check the fitting / sealing
    of the transition piece connecting the throttle bodies to the cylinder head face too  :028:

    Thanks Coconut I will mark it down so I don't forget.   I take it back next Wednesday.    Will be sure to update what was wrong (if they find anything)

    Nothing about the new tune requires an adjustment in fuel octane.  Your dealer is misinformed

    with the engine cold,
    turn on the bike and without touching anything leaves the idle until you hear the operation of fans.
    So all the sensors of the bike is included reset the tps for the electronic acerlerador, will notice a change to the lead

    Okay, took my bike to the dealer for the slow pick up when applying full throttle.   After the mechanic/tech rode it as well as the service manager both agreed that there was a problem.   What they decided is to order two new sensors that operate the throttle by wire system.   Hope that solves it.
