    .64 Superplush...
    I have done lots of searching on this and this worked well for me. I weigh 200 lbs..without gear.
    They will just drop right in.. easy..

    .64 will drop in but there are guides that run inside the spring and in some instances those interfere and rub against the internals.

    To do it right you would want to remove them from the forks and mill them down.

    The long thing at the top of #30

    If they rub it will quickly contaminate the oil with plastic shavings which get into the valves etc.

    Jeff at Slaven's Racing told me .62's. So that's what I ordered.
