    It doesn't have to be top of the line oil...just clean decent new oil.

    The forks run on teflon bearings against the alloy and against the hard chrome so any old oil is going to lubricate.

    A high viscosity oil is going to hold it's viscosity longer and thus damping qualities but is probably a waste of money in the AT forks which are going to need more regular oil changes than most.

    Guess what I'm trying to say is that it doesn't matter how expensive the oil is, it's not going to make a difference to the wear...it just needs to be changed more often to get rid of the debris.

    That's been my main bug as well. I know I had stiction- which is what I originally complained to the dealer about before this wear-thing raised its ugly head. But I know some guys who have had their suspension seize up almost solid. Mine has never been that bad- I can live with the stiction, but will it get as bad as Craig and my mate Darren's? And how long?

    As for people reporting no wear/damage - there is still the question whether they just missed it (oil sheen inside etc), as we know it is really easy to miss. I missed mine the 1st time I looked.

    I had a look at two sets of KYB's, but both needed a rebuild as well. So IMO not really worth the risk and the expense when you don;t know how bad things are on the inside (one set seems like its been run without enough oil for a while)

    My warranty runs out soon, so I'll be taking the bike to the dealer for a good check. There's at least one oil leak that I know of that they have not managed to fix.

    As for maintenance on the suspension - man, if these forks need rebuilding every six months just to keep them going, then I'm thinking switch to conventional forks. The performance is not that much better to warrant all this crap (for me at least).

    Hoping for some directional guidance soon.

    I think the hardcoat will stop the issue.Shit is pretty tough.Do you have shops down there that can handle doing tubes.I know it requires some special anodes to get to the inside of tube properly.After I am done with this I am just going to ride and not think about it unless it breaks.If tubes are shot in couple years will swap front for something else.I don't think my new hard ano is going to wear.Will flush tubes and put new oil in after a 2000 mile break in and just think about pretty lady's and good whisky.

    The suspension gurus say to lower the torque of the lowers from 25nm to 15nm or so but i'm sure you already know this.

    1st thing I did when I brought it home with new tubes.Still ended up with same wear marks.I think it's just shitty ano job.With all the issues kx,s are having on the showa forks with anodizing I think maybe showa needs a better ano shop.

    Just some feedback on the KYBs.. Have 5000km on them now (Pretty hard mileage too).... Wanted to re-valve slightly softer, so full teardown.... Absolutely no sign of wear on the coatings, and oil came out clean.... So holding thumbs...now gone to 2.5wt oil. (I guarantee the showas would've been toast by now)
    Shock teardown as well (to try 2 stage stacks)....oil looked ok....so looking good.

    I've got springs, front and rear on order from Cogent. They spent a good 45 minutes on the phone with me, advising on set-up. Frickin awesome customer service and knowledge.
