    Question Fixed: FZ6R Hesitation on Quick Throttle Open/Close

    Hi everyone, I'm new to this forum!

    I purchased my first bike in May of this year, it's a 2013 FZ6R in White with Red frame.
    Currently has around 18000km.

    Mods are TB Carbon Exhaust, PowerCommander V, K&N Air Filter, "Airbox Mod", FZ1 Handlebars.

    The bike runs fantastic, starts well, shifts well, etc... Only issue I'm noticing is that once in a while, when I quickly give gas/let go of the gas, the bike kind of hesitates. It bogs down/chokes. This happens cold or hot, even at 100 degrees Celsius running temps.

    The maps I have tried on the PCV are Marthy's Sport RevA (currently using), Marthy's AdvGear RevB as well as the stock TB Exhaust map.

    All give the same result. Is this normal on the bike? My friends all have bikes (sport touring and supersports); none do this.
    It's most noticeable when downshifting, when I try to rev-match it'll sometimes choke.
    The bike doesn't hesitate/choke when accelerating normally.
    Never stalls, just kinda doesn't rev up...

    (Note: Did the same thing with stock air intake)


    Any ideas?
    Thanks!

    Try to enable the acceleration pump on the PCV. If you open the "note" on my map the settings should be there. I can't remember the exact settings but it was something like
    75% throttle
    15 Rev
    12% Fuel

    Let's see if that help... You can go up/down on the %Fuel to get the best out of it.

    I think that fixed it!
    Kinda annoyed, the guy I bought it off had the PCV already on it.
    When I went to see the feature, it was already enabled with 30% fuel.
    I think it was set to 80%, 50 rev, 30%...Probably was flooding the engine when giving it shots of gas, causing it to hesitate/choke.

    I set it to 80, 20, 10 (your Intermediate setting in notes)

    Thanks so much for the response!
