Front Fork Overhaul ..... It's The Pits

Discussion in 'Suspension help' started by oldtech, Apr 1, 2020.

  1. I know there's a 916 fork repair thread running on here but I didn't want to hijack someone else's topic ... :)

    I'm about to replace oil seals , dust seals , and bushes on the standard Showa forks on an ST4 and I've just spotted a couple of tiny pits on the chrome , of one leg only .

    I've attached a pic but it's difficult to make them show up

    Is it a certainty that they going to cause early failure of the new oil seals ?

    I suppose I could just do it , then wait to see if the Kiss of Death comes ... :skull:

    I've thought about having the hard-chroming done , or buying used parts , but it seems like an expensive fix for a 20 year old bike , with only two tiny pits ...

    I've watched and read various things about using super-glue , JBWeld or Araldite to fill tiny pits , followed by "shaving" then carefully rubbing down with very fine wet-and-dry
    .... it appears to be a temporary fix , at best ..... or not ?

    Anybody tried it ? ..... any thoughts or suggestions ?

  2. If you can't feel them with you fingertip I'd be tempted to tempt fate, if you feel them raised then wet and dry and again tempt fate - shitter of a thing to find

  3. If your forks aren't leaking now then I waould say they will be ok. In any event polishing them up with some v fine wet and dry wont go amiss.

  4. I've already worked them with 800 emery ( wet ) and then 1200 ,
    first dry then wet and I can still feel them .... just about .

    @Topbox
    The seal on that side was already weeping slightly , when I had to leave it standing 4 years ago .... and now I know why
     
  5. A bit of super glue over the pit , then sanded once hardened will fix it

  6. I just couldn't decide between reassembling as things stand ,
    or using the glue , but the fork is on the bench and super clean ,
    so I'll have a go .

    Now I just need to decide between epoxy and super-glue ....

    Since the first post , I've been searching " The Sprawl " for information .
    This bloke goes one step beyond , and uses an old AA battery and a phone
    charger to zinc plate the pits before using the glue .... I kid you not !
