Thread: Stiff Throttle?

  1. #1

    Default Stiff Throttle?

    Sorry, this is quite a difficult one to put in words, but I've got a feeling that my throttle might be a bit stiff. It seems quite hard to give a blip for the downchange, which is spoiling my shifting. Going up is no problem of course, just ease the throttle and it snicks on home.
    I was just wondering if this might be a known issue on the FZ, before I start trying to sort it out.

    Thanks.

    It would be a bit more easy to diagnose if you mentioned if you had a gen 1 or 2 but you should check to make sure your cables and throttle bar end has been lubed and that there is no binding or severe bends in the cables themselves. Make sure both cables are adjusted properly and any return springs are in good shape. Any moving parts should be free of heavy grease and/or crud that may accumulate. These simple steps should give you a throttle that responds like a new bike.

    Check for the obvious stuff first. See if the grip is rubbing on something, see if the throttle tube is rubbing on something. Lube up your throttle cables thoroughly as well. Take off your bar ends and shoot a tiny bit of a thin lube between the throttle tube and the bar if it seems corroded there.

    After that, see if your cables are bound somehow; crooked or with tension.

    Pull the rubber grip off of the throttle. Underneath will be a plastic tube attached to the throttle cable that lives over the handle bar, lube the whole thing up good including a little light oil into the cable outer tube and reassemble.
