    Have a friend with a fork brace for the XJ750. Might fit a 900. Bit dubious whether they help or not. A friend had an XJ550 with a home made one. Gee the forks are bent or something sez I idly pushing down on the front. I never noticed sez he.

    Hmm, pass me those allen keys will ya. [F5 undoes forkbrace] front end now moves with aplomb. Nice engineering.
    Don't you look at my accountant.
    He's the only one I've got.

    Nup wrong bike try Z900s... Xj 550,600s and the 650 handle quite well.

    How old are the rear shocks?
    I've seen a heap of "frame flex" cured on older bikes just by replacing the rear shocks after being told
    "they all did that, nothing you can do about it"
    "If you can make black marks on a straight from the time you turn out of a corner until the braking point of the next turn, then you have enough power."

    Pretty old.. There is someone local that I can take them to and guys down Levin way that do it too.
    Could be the next best place to spend some $'s

    XJ's, old drive-shaft bikes flex under power and de-cel... its in their nature because they're not ballanced right... this is most likely why you've just replaced the swing-arm bushes, you maybe able to reduce it but it'll always be there, you shouldnt notice it flex going around corners too much (unless your try'n to power slide out?) if it does have a look at front-rear wheel alignment if you get my drift or even trebble clamp alignment and/or front and rear shocks.

    For sports XJ:
    Lower the front and put on clip-ons, then thrash the hell out of it.

    for cruiser XJ
    Lower the front and put on clip-ons, then thrash the hell out of it.

    ... you'll forget all about the flex

    edit: didnt read properlly... forget the swing-arm comment

    Moving along tho what do you think about the FJ's. Seen an '89 for $4k5. I know not shaft drive .. but could be a replacement ??

    Those pics were taken at Gizzy 2002, they still race there now...
    I like the FJ1200 (almost stacked one when I was 16 and stupid) plenty of power and comfy... but I think $4000 is too much for a 16 year old tourer, 3k would be better... If ye seek, ye will find.

    Not had much to do with the 900,but my mates 750 had lotsa flex somewhere,it'd wobble like a bitch at 180k,in fact so much it threw him off on day....
    Have you checked the forks,frame,arm etc for alignment? You'll never cure it if it's bent.
    I'd try the forkbrace/armbrace/framebracing if you're serious and it's straight.

    Try welding it to the side of the harbour bridge. That oughta cure it flexing.

    If they are the original factory shocks they were probably stuffed 10 mins after leaving the shop and are of the unrebuildable type.

    Slap a set of Kagons or Ikons (the old Konis) on it and all will be well... Ok, better...

    I'd seriously think about replacing the fork springs as well.
