    Yeah thinking a new one either way as Nix will be sold if I enjoy riding the FZR enough! The riding position is very different though, not sure at this stage...

    Picked up these remains of a Yamaha YB100 yesterday and spent today swapping the good bits onto my YB100 that I am taking to the National rally in Canberra in March.

    Rebuilt the ZXR today, using genuine parts is just so nice :D The ride home from the shed was chalk and cheese compared to how it has been, zero regrets in busting my bank and back doing this haha!

    Downside... The front wheel doesn't want to line up, driving me mad. I feel like there should be a metal spacer between the wheel and the right fork but none of the diagrams or pictures I've seen have one.
    The problem occurs when I do the axle up nice and tight the studs on the brake disc foul on the Calliper bracket and often the lower mounting bolt. Levering the fork outwards by a fraction and tightening the two lower bolts I can force the wheel to clear.... Just.

    Anyone got any ideas what the hell is going on?

    If it's an alignment problem, loosen the triple tree and pop everything back into square.

    If the front wheel is wobbly, you need to replace the wheel bearing

    This is where it gets weird. I did exactly that and it made everything worse tenfold. Got so bad I couldn't rotate the wheel.

    But it's not wobbly wheel syndrome, I rode it home and it was awesome. The vibration came from applying the brakes on the way home.

    Check that your disc isn't loose......shouldn't be !! If the disc is ok, perhaps it could be the disc itself.....warped or far to thin, check that out also.

    Disc is tight, shouldn't be warped - it's brand new metalgear discs.

    Going to investigate after class today

    Try loosening the clamps and rotating the fork tubes. One may have a slight bend causing the misalignment.
    Make sure there is no old gasket or bits of crud behind the disc mounting face.

    When I had them apart the inners looked great, no bends that I could see. Might check the outers for a bend...
    Argh. This bike drives me mad

    Sounds to me like something hasn't been assembled correctly

    Fork Stiction etc.
    I have not seen the ZXR forks but they appear to be a floating leg assembly. This arrangement has a spacer on only one side and pinch bolts on the lower fork leg on the other. They are supposed to be free to align perfectly, when tightened, into a position that will create the least amount of fork stiction. When confronted with an assembly it is useful to understand why it was designed in that way. Then you can assemble/tighten in the correct sequence

    With the floating leg arrangement (one fork leg is positioned by pinch bolts), this is my preferred assembly method.
    1/ tighten axle.
    2/ Remove fork caps and springs and allow forks to bottom.
    3/ Tighten fork leg pinch bolts
    4/ Support front of bike and test full travel of wheel. If there is excessive stiction, try rotating a fork stanchion ninety degrees at a time then retest. If you are really pedantic, you can find the two points where stiction appears to increase and then rotate to the centre of that position. If something is bent it will be difficult or impossible to achieve the full range of fork travel.
    5/ Refit springs and caps.
    Steps 2, 4 and 5 are for people that race bikes or like things to be perfect. Actually, for a race bike, I test for the least stiction when fitting the individual forks into the fork crowns. It is also a good opportunity to test the dampening performance on each leg.

    However, as your bike is 25 years old there exists a strong possibility that it has been altered by previous owners. You must assume that nothing is correct and work from that assumption. Also last things first, you fitted a new aftermarket disc, that would be the first thing to check. Confirm with owners here on the forum what the correct offset of the disc is. Don't assume that it fits correctly. That recently happened on this forum with sprockets for late model FZR250s, all of the aftermarket products are wrong.
    cheers
