    The OEM hubs are fine. I don't think anybody makes a hub that will fit this bike. Yet another great engineering decision by Jans and Franz.

    I really banged my rims riding around Goodsprings last year. Guess its time to start shopping. Just passed 27,500 miles this afternoon.

    Does anyone have an old rear shock that they are no longer using? The shock bushings (rod ends) have developed play on my xMoto (Sachs shock) and it's making a clunking noise. Can't seem to source any replacements... but I could easily press them out and replace with some new ones.

    I determined the issue was that the spherical bearings at either end of the shock have developed play. The bearing is printed with G14DX CCVI and I couldn't find any online.

    Had to make a bushing using Delrin and a spacer. But this doesn't allow for twisting movement.

    Looks to be the aluminum subframe. You can beef it up and make it durable. The TT subframe is a pile of cash and works well. It does add a pile of weight to the rear of the bike as well. The pannier loops can fit various cases, but don't work well with a "Giantloop" style bag. To make soft bags work better, add a plate to the pannier loops.

    It's only a couple pounds heavier than stock. I was surprised how little.
    Subframe + XRack are net gain of ~10 lbs over stock.
    Stock subframe tail official weight limit was 11kg (yeah right), not sure how far north the TT limit is.

    I've been using the Giant Loop Great Basin with a set of DirtBagz racks for some time now. The DirtBagz racks provide some crash protection as well as a point to secure the Great Basin. The Great Basin will not hold spares for much of a wilderness trip and all of your camping gear for anything other than a couple of nights of good weather. Plan on a couple of dry bags to go with it for camping. If left on the bike it can collect a lot of stuff that might otherwise be left at home.

    That KTM nose job looks great, Rocky. I think I may have follow your lead later this year and do that myself.

    inlet valves are too tight. I'm getting shims but should I try to match the outer spec 0,11 or keep closer to the inner spec 0,03?

    do valves get tighter or looser when they wear?

    Tommy,
    Here is what I know about valves - all learned online so some might be suspect :rofl The valve edge and the valve seat (in the combustion chamber part of the head) wear fastest which tends to make the valve lash clearances tighter over time.
    What I plan to do with my valve adjustment (cam out currently) is to go towards the tight side but not all the way down (because any later wear would make it too tight which would prevent the valve from closing completely). My theory is that the larger clearances cause the valve to open microscopically later and minisculely (is that even a word?) less distance somewhat limiting the charge entering the cylinder.
    Lots of people just shoot for the middle of the range.

    I got a great price on a Sprint ST becuase the PO had the intake clearance too tight and the thing wouldn't start when hot.

    thanks!
    in conclusion: the tighter the better IF within spec?

    bli55 thanks for pointing that out
    and leafman60 thanks for the explanation.
