    There should be no stiction in damper tube/cartridge when cycling damper rod through stroke.
    I hope for you, that when forks were revalved/rebuilt the damper tube hasn't been clamped in the middle.
    You can only clamp damper tube near top of tube where peening holds the 2 pieces of cartridge together. Anywhere else will very likely distort cartridge.

    As for bushes, i had 2 sets with about 30k km each. Inboth sets, stock ano wore, as did Kashima recoat,no bush had any measurable wear. Could have continued to use them.

    Damper should move smooth as silk.Somebody messed up when they revalved them.That really sucks and I would get on the phone to them.Be interesting to see if there's any kind of marks on the cartridges from being clamped.

    Konlflict emailed me concerning my damper issue after reading my posts on this forum.
    I appreciate their immediate response.
    My response included a video.
    Details later after resolution. I really want to ride this MC! :becca
    Thanks again for individual help on this thread/forum.

    It does not surprise me Konlflict got ahold of you.My only experience with them was a custom spring but I read a lot of stuff about his top notch work.

    I had a decent experience with Konflict also. I was delayed getting my shock back because of delivery issues, not them...the usps. I did my front forks myself and saved a load of money and put a stronger spring on the shock. soon it became apparent the shock would need revalved to match the spring as i had built a very efficient pogo stick. i sent to him because i didn't want to mess with the pressurization and buying a bunch of tools i didn't have for a one time job. worth the money.

    Sending my forks and new ATAS upper tubes to Konflict for their inspection and reassembly. I was not confident on disassembling the damper tubes and inspecting them for the 'binding'

    mid stroke...? just the one damper?
    weird. Only thing I noticed on mine was some wear on the rod...think @Motociclo said it was due to flex. My oem tubes were done after 8k km I think...that was my issue..

    Only disassembled the left fork. That was enuf to understand I don't have the right tools for the job!
    Need to get them posted to Konflict tomorrow!

    I’ve set my fork oil at 55mm with springs in. Contemplating 60mm at next fork service on the theory that it will help it feel a little more cushy on the highway at speed. Does this sound right?

    It will only make the end travel on a big hit softer.Not enough pressure build up the 1st half of travel to make a difference. Try backing your high speed adjustments out more.Can also try backing off preload some.

    I have almost 10,ooo miles on my 2017. Did a 100 mile mixed ride a couple days ago. Some county gravel, some slab, some washboard. Anyway this morning there is the dreaded spot of oil under the left fork. I don't have seals at hand. I'll need to order some. Anyways, I thought I would try cleaning the seals. I don't have the motion pro seal cleaner device. so I cut a piece of plastic from a container. The kind that is packaging for stuff. Pulled the dust cover an when I did it just almost fell to the bottom of the forks. It doesn't fit tightly against the fork tube. There was plenty of grit inside. I cleaned the seal as best I could. From what I could see with magnifying glass and flashlight. Seal actually looked pretty good. but that's very hard to see. Anyway, since the left seal seems loose, I pulled the right dust cover. It fits tight on the tube as you would expect. There was no dirt inside there. on the right one. Took it out for a short ride. Probably 10 miles. Abused the forks a bit, and no leaks. I'm sure it will leak in the not too distant future, so I'll order new seals and get ready. But thought it interesting.

    Get the Kawasaki seals save the elastics and set fork oil 55mm from top with springs in.

    I need to research the best seals. I saw mention of Kawasaki seals. I should do the springs and valving at the same time. again, I'm not sure what to put in it. It's so lightly sprung, its ridiculous.

    If you are 190 to 220 lbs the .72 are a good all around spring. The .82,s in mine are on the stiff side but great for my 2 up riding. At 205lbs if I used bike for mostly 1 up I would go to the .72,s.The cogent springs are drop in and the racetech are repurchased so you must cut your spacer for proper preload.

    ^^^ Thanks. I don't ride 2 up. But sometimes with my camping gear. And I'm about 235 lbs with boots and gear.

    Go with the .72,s and you will be very happy.If you give Rick a call at cogent he may even suggest a little lighter. He suggested. 72 for me but I put in the .82,s and wish I would have listened to him.I did it because I ride a lot of sand and thought keeping the front end higher would help some.It was a failed experiment lol.

    I'm150lb and have Raceteh 0.75 springs with cut down spacers (could be cut another 5mm). Zero preload, 25% rider sag.
    Matches the rear 100N-m spring. Zero preload 25% rider sag.
    The bike sits higher and leans more on the Camel Toe side stand.
    Suspension works well off-road on baby head rocks and washed out FSR's.

    I don't want to start a new thread so hopefully I'll get some responses here.

    I really like everything about my Africa Twin except the way too soft rear shock. I can either have it re-sprung and re-valved which will cost me $400 or so or spring (no pun intended) for an Öhlins or Touratech. Both of those shocks run about $1,200 and I'd rather save that money if I can. I don't beat the crap out of my bikes but I do need a stiffer coil to support my fat ass as well as 50 pounds of gear.

    If anyone here has either re-sprung/valved the stock Showa please let me know your thoughts. The same is true for either a Touratech or Öhlins upgrade.

    Thanks.

    I know this is a really old post but can you confirm what caused this wear in your fork tubes? I read ahead several pages and the word disc was mentioned as well as plastic fork guards. I just check my AT which only has about 5,000 km but I have zero wear from the stock one piece fork guard and cannot see how it can wear a groove anything like this.

    Maybe you changed something from stock?

    Thanks.
