    I used a 0.05mm shim in my original AT forks to reduce slop.
    The slop may contribute to anodising lose, made zip difference to my stock tubes post Kashima coating.
    Tubes are just to flexy.

    I found the ATAS fork tubes had tighter clearance.
    From what I have researched, 0.10 to 0.20mm is a good bush/tube clearance.
    I found the ATAS tubes were in this range. From memory, 0.16mm on mine. Not worth shimming.
    My original AT tubes were 0.25. Way to much.
    With shim, 0.15mm.

    Where do you guys source your material for shimming the bushing?

    I'd be curious to know if Ohlins is aware of this issue? Or the retailers who re-sell Ohlins? If you had purchased your forks new, would this be a warrantied?

    Not fixing this problem doesn’t seem to bother Honda. Maybe Ohlins would care more about their rep? Hope so...

    I have a supply for 10 lifetimes. If you PM me a US address I can put Africa twin sized pieces in the mail box if you are serious about doing it. I’m happy to help out AT do it yourselfers because so many of the people In The know here have helped me with their time and knowledge.

    I ended not using the shims though when I put ATAS uppers on my AT lowers.

    The problem is a matter of degree. For some people they will never have a suspension dissatisfaction they ride tame and like the Cush. The guys that hang out here are the obsessive hobbyists in pursuit of the perfect suspension and we abuse it along the way. I don’t fault Honda too much because motorcycles need a lot of maintenance in general, but the springs could have been made stronger with an extra shim or two in the valves for $0.00. That was must have been a compromise to hit a deadline. Like they saved it for last and ran out of time to tune.

    They had a 13 year gap to tune it ;)

    I don't think they care.
    The excuse for lack of top out is the tampon does its job.
    Coating? you're riding it too hard.

    Not even going to bother.

    Same deal as honda..prob even less care now that they switched hands. If Rossi is unhappy with his setup, he's got a few ohlins guys mulling around his garage...I checked, there's no ohlins guy hiding in mine. Just riding it now, not really getting bothered by it. Will check the forks this winter for coating wear

    someone said they were too busy on the dct...likely very true. Just like yamaha, suspension is an afterthought.

    If one can actually pull it off, SSS complete forks, AT bottoms, or Ohlins bottoms, simply sell the forks separate to the bike. Or lose the one disk.
    But it's not a straight forward job. Far from it. if @Camel ADV has four or so vids on the process, it's not a walk in the park.

    The lower AT lugs don't have enough meat on them to machine out for the extra 4 mm,I have a set of sss forks if I need them in future. As of now the stockers are holding up well with whatever Rick coated them with.The sss forks would be sweet but over kill for my riding now.Like you having real offroad bikes keep me from pounding the shit out of this pig.

    correct. @Motociclo mentioned the lack of thickness.
    Mine still gets a workout, but not the really punishing kind.
    Will ride the piss out of the Beta next few nights.

    Just a question.
    Are we sure Öhlins fork lugs are just "plug and play" to a Kayaba SSS fork legs? I mean: threading is the same?

    And... would Öhlins offer lust the lugs???

    Even if the Ohlins lugs fit SSS tubes, from memory Ohlins are kind enough to use left-hand thread to hold in damper assembly to lug. Won't be able to screw in KYB inards to lugs.
    May or not be the case with Ohlins AT forks, but other Ohlins forks are like this.

    Here are part numbers for Ohlins lugs,

    21935-01 left.
    21935-02 right.

    Wow that would be cool.I am guessing RT could have new chrome tubes made to fit lugs if needed.This really gets me thinking.Have your cake and eat it to.Guessing Rick could make this work also and friendly to work with.
