    Default Problem at 7000 rpm


    here is the problem on my FZ1 2006.

    Just like that, my bike started to lose power over 7000 rpm. The bike was still running and accelerating when I was under 7000 rpm.

    On the idle, I was able to go to the max rpm. It was until last night, I started the bike, and now, it just barely go over 1000-2000 rpm and a smell of fuel. When I turn on the ignition, the flyes doesn't open at all.

    Also, way before my bike was like this, every time I put the ignition on, there was a tic tic tic tic tic tic noise, even after the injectors were set. Now, it doesn't do it anymore, coincidence... Don't know.

    What I found on the Internet until now :
    - TPS problem
    - Sub throttle servo
    - Exup (no more there since I put a Two Brothers exhaust last year and everything went fine)

    What I did until now :
    - Spark plugs have been changed (they were due)
    - Air filter have been changed (they were due)

    Thank you,

    Hi Patrick,

    Check for a kink in your fuel line.
    It's a common problem that may explain your over 7K rpm problems.

    There is a fuel line mod that I and others here have done.

    A quick search for "Fuel line Mod" should be all it takes to find the write up.

    I believe that Ballmead is right about your fuel line being linked. But it also does not sound right for the secondary flies to not cycle open and closed upon turning the ignition on. Possibly check for trouble codes.

    The only problem you should have at 7,000 RPM is your arms pulling out of the shoulder sockets.

    Good call on the fuel line but is it likely to kink unless the tanks been lifted of late ? .. I've read a few posts of the secondary flies servos seizing up though.
    Cheers Delbert

    Tell it like it is
