    It is possible, but quite difficult. Easier to remove forks, and disassemble on bench. Not worth the hassle doing on bike.

    I always loosen the top triple clamp bolts, crack the cap loose, THEN loosen the lower triple clamp bolts and remove the fork legs. The lower triple clamp is the perfect vise for holding the fork legs.

    I am a very happy 2016 AT owner. While I have not experienced any stiction issues yet, I suspect at some point I will. When I do, I'll simply pull the forks and send them to Cogent. I don't get too wound up about these things. Every bike I have ever owned has had its issues. While we'd like to have perfection, it's never going to happen, and especially on a newer design. Maybe in a year or two the engineers at Honda will quietly make a design adjustment, and of course, never say a word about it being a "fix".

    Well after discussing pricing with Konflict Suspension to fix the stock Honda tubes it made more sense to go the KYB SSS route. Already purchased some mint looking KYB SSS forks off ebay. Now on to getting these fitted to the bike.

    What did they propose to do to the forks, and what was the quoted cost for the work?

    Because of the wear on the inside of the fork tubes, new fork tubes are needed. Those new fork tubes would need to be Kashima coated and then I would also need to put in slightly larger bushings.

    I do not want to post the pricing that I got here publicly but if you are interested PM me.

    I am really interested in your 1290 SDR. I think that is my dream bike.

    Yes.It will allow you to over extend fork if you have bike high enough clean your tubes well 1st.The rough machining on chrome tube will show some when extended enough were you can see inside.You most likly have to pop calipers off forks and unhook speed sensor(will need to remove fender on that step).tape some rag onto a stick soaked down with carb or electrical cleaner to wipe inside of tube.Damage is 220 to 240 down just above lower clamp on mine.My seals still worked after I over extended as the rougher machined surface is chromed very smooth and will not cut seal.I removed my forks but is possible the way you are thinking.Honestly at that point you are close to having the forks off because all the hard work is done lol.Also my left fork showed the most wear as posted by another.

    Very odd. An Oz member herewith fork tube wear (@Motociclo) sent his forks to Japan to get coated by Kashima themselves. They didn't tell him he needed new fork tubes.

    Since your forks were still working fine and you may buy an SDR anyhow, maybe hold back on that conversion for now. ;-)

    Buying a KTM to fix a Honda reliability issue is like giving up red meat and taking up crack smoking because "red meat will kill you".

    I did say "dream bike". The concern from Konflict is that there will be a low spot in the area of wear and applying a Kashima coating is not going to fill in that wear spot. The issue of having to much clearance is still going to exist so this could be another bandaid to cover the bigger issue.

    The fork conversion is not a priority for me now. I have purchased the forks already due to finding some in fantastic shape. I will now begin the slow process of getting all the pieces fabbed that I need. In the meantime I will be putting the stock forks back on the bike and ride.

    The wear in beginning Is very light and when stripped to recoat may be completly gone.At 7200 mine would have dissappeared with a recoat.I have 2000 miles on my new tubes and will spin them tomorrow.Have only a month of riding before snow flys then will take my new tubes off and send to Danco in California for hard coating and make some adjustment to my compression valving as it's still a little soft.A big thing will be to replace teflon bushings as the old teflon will have the crappy anodizing stuck in it that will wear new coating if left.Will make other mods to chrome tube also.I also always rub my chrome tubes down with 400 wet/dry on 1st rebuild.This has always helped my seals last longer and fights stiction as it allows surface to carry some fork oil with it.

    Funny how some, facing an ever growing list of Honda AT problems, like to deflect by making fun of KTM. I think it is likely few of them have any personal experience with KTM ownership.

    Pointing fingers at KTM is not liable to be effective in fixing problems with your Honda.

    "An ever growing list"? :photog

    Show me the AT's version of this:
    http://ktm950.info/how/ktm_950_issues.html

    The difference between the AT's problem thread and that website? You could own an AT and never join this forum...visiting that website is practically a prerequisite to KTM ADV ownership, half the owners will tell you as much!

    Funny how many KTM owners have become the most defensive owners on the www these days. And they used to make fun of BMW owners! ;)

    After a re-spring to carry my big butt, my 1290 does too. Very impressive.

    If there was such a page, the "CRF1000L Africa Twin problem thread" of this very forum would probably have been much shorter than 170pages.
    The Advrider "Hall of Wisdom" is full of DIY and repair info on GSs, KTMs and KLRs. I don't think it has anything to do with reliability, more like how popular these bikes are so lots of information became available and was collected in one place. Same like the faq.f650.com page.

    I'm sure as the CRF1000 will continue selling in the next years it will receive its own page, like its very successful and popular older sibling, the XRV650/750 that was not available in the US.
