    I recently changed my Fork Seals for my 2KR and
    I replaced the Fork Oil. Im not exactly sure how much to put in.
    I put it in according to the height from the top of the stanchion down inside, but im not sure if ive done it right.
    What height from the stantion inside the fork should it be, measurement wise?
    The forks arent too bad, but can i add more than specified to make em a bit harder without having to cut springs?

    p.s Sorry bout length of post

    I'll disagree somewhat with Grey Import - you can add SOME more oil, this is a standard fork tuning technique. It must however be done carefully and methodically, or you will indeed blow your seals.

    This is generally done as a final step to adjust final travel near the stops, once spring trimming (to increase the spring rate), spacer resizing (to set the preload) and oil viscosity selection (to adjust damping) have all been completed.

    Thanx, the bike isnt rego'd atm, so i havent been able to test the suspension yet.
    Im sure they will be fine. It would be nice to have em a bit stiffer, but i cant really be bothered.
