YZF750 Neutral Problem.

    Hi All,
    Thanks to those who have replied to my previous message. I do
    however have a further problem:

    I recently purchased a YZF750 - 1996, it has around 3000 miles on the
    clock and looks like it has only done a handful of miles since 1999.

    I have only had the bike out a couple of times since I bought it - and
    this problem doesn't seem to be getting any better.

    While the engine is running I find it _REALLY_ difficult to get in to
    Neutral. From 1st it takes a quite large force on the gear lever to
    shift it up, this shifts right past neutral in to second.

    Going down from second it sometimes goes in to neutral but mostly
    shifts in to 1st...

    When I got the bike the oil was a really nasty colour, which I put
    down to the long lay up - so it was changed. The clutch fluid has also
    been replaced. There is quite a 'kick' as the bike shifts in to gear
    but it doesn't creep forward.

    Any ideas?!?

    Thanx in advance,
    Anna

    I have a 1997 Yamaha YZF750, which I bought new. Also would like to sell
    this 4000 mile mint YZF as I have a new bike! But, the gearbox in the YZF
    is the best I have sampled on ANY bike. Neutral is very easy to find. The
    gearbox always worked well. Wish my new Kawasaki shifted as well!

  3. That's the cheap fix: learn to ride it as it is. This is something you
    should be able to do anyway, should the cause turn up while you're riding.

    The large force required on the shift lever points to a dragging clutch.
    You'll be much happier if you fix it.

  4. Adjust the chain and/or just try easing it forward a tiny amount with
    your (other) foot while you flick the gear lever up.

    (Anna) wrote in
    Dragging clutch plates. Experiment with blipping the throttle while trying
    to find neutral. The 1100 Kat is the same way due to its hydraulic clutch.
    Blipping the throttle forces the clutch plates to slip, and eliminates a
    good deal of the force that's fighting you in your search for neutral.

    Also, insure that your clutch lever is adjusted properly. There should be
    no more than 1/8" gap (rule of thumb) at the lever hinge when the cable
    goes taught during lever pull.

    Good luck,

    Steve

    Hi All,
    Thanks very much to all those who replied. i`m happy to say that I
    took the bike out with new oil on Saturday and after a hard ride the
    neutral problem dissapeared. I guess it must have been the old oil
    messing up the clutch seperation..

    Thanks again,
    Anna

    Yea, it's totally screwed. Just ship the bike to me and I'll take care of
    its disposal.
