    2 things here Dabbler.
    1. I would recommend only use genuine Kawasaki seals. These are a bit more expensive but IMHO worth every penny as they are far better quality. They can be bought from Zpower with whom we get a club discount.
    2. Yes there is a way to do it. A standard nut fits into the screw inside the fork leg to hold it while I turn the external cap head screw. I simply lock 2 nuts onto a piece of threaded bar bent like a handle at the other end. I can’t remember if it’s an m10 or M12 nut. Think it’s M12 but will check later for you.

    cheers KAPTAINKWAK i got one done its a 19mm head bolt i used with 2 nuts locked on neat trick that will remeber that one so to the fluid when it says 185cc fork oil is it the same as 185ml

    Again yes. 185cc = 185ml. That is one of the joys of the metric system. I also check the measurement (433mm +/- 2mm) from the top of the stantion to the fluid level) to be sure. Make sure the station is fully extended.

    Kaptain – can you explain the two locked nuts method? i can’t think what you mean?

    No problem Jon.

    Get a piece of M12 threaded bar approximately 650mm lg. Bend around 150mm at 90 degrees to form a handle. On the other end fit 2 M12 nuts and lock them together flush with the end of the bar. The 19mm nuts fit inside the inner fork piston head to hold it still while you undo the allen bolt on the bottom. This is only good on the LTD forks. For the B1 and B2 forks I got a think it was 9/16″ socket. I heated it cherry red and forged it over the top of the fork piston head and used a standard 1/2″ ratchet and extensions to hold the head. On B3 and B4 forks it is different again. I believe a square taper of some form is required.

    Ah yes i get it now..

    When removing my ones i grabbed a long piece of 15mm copper tubed, squeezed it oval and it was just right to hold the top of the piston head.

    Now that it’s dis-assemebled im’ thinking i might modify the piston heads to fit into a normal socket by pushing the socket onto the pistons you can see the tight spot and just dremel them away- i can’t see that it’d cause any problems.
