    For on-road ease of flat repair, I've sealed my rim to use tubeless rubber on my F8GS.

    EDIT: Thanks!!! to Cyborg (his link) (Finally found the link...)

    "Seals All" went into the syringe. Goop went directly from tube. Apply two layers of Seals All. Wait 30min then apply one layer of Goop. Let stand over night. Remount.

    Intersting, now go ride and check back in 10 or 15 thousand miles. I like it.

    much easier than trying to move spokes to the outside of the rim.

    Why does it feel like the boat is sinking and sharks are circling? :D

    How did it balance out after adding all the slime, goop and goo? Did it take a lot of weight?

    I put her on a Marc Parnes balance tool and spun her both without the tire and with the tire. Neither one showed a significant heavy spot, i.e. after ten spins the wheel never once stopped in the same spot.

    Lucky or incompetent. Either way there is not a significant imbalance.

    I'd be real curious to know what your rate of leakage is (if you plan on tracking that), and how far you feel safe lowering the pressure when off-roading.

    I will definitely track it but I don't off-road so I won't be playing that end.

    I'm curious about the other end of the spectrum-- fast. Will the centripetal force cause leakage as the sealant is pulled to the perimeter or will the tire pressure keep it all in check?

    The cool thing about the Parnes balancer is you don't spin it and watch where it stops each time. Put the wheel up on the rig, let it settle. That is the heavy spot. Mark it. Weight the opposite side of the wheel until you can put the heavy spot at 9 o'clock and 3 o'clock and have no movement.

    Good to know. I don't use the balancer much.

    I still think she is basically balanced.

    Saw a RR for..."Gregor" I think where he did a 17/19 combo on his KTM 950, made the rear tubeless in this manner and went on a trip, 2 up with gear on the Translab. I think he only had problems with the road conditions eating up the tire. It still did decent (able to limp in to town) even with multiple string plugs.

    I've done 18k with my Tiger after tubeless conversion, no issues, and yes it gets ridden off road.

    I assume you would break the seal if you need to tighten the spokes right? (The only seal-all I've ever used sets up pretty rigid.)

    They don't make a tubliss for our rear, and I believe the front 800 rim is also too wide. :bluduh


    DB, you didn't have to alter anything to get the tubeless valve stem in, did you? If not, seems to me the worst case scenario is to do this mod but then travel with a spare tube. If something craps out or you get a bad cut that you can't fix, rip out the stem and run a tube, right?


    I'd run tubliss if I could; the idea of the rimlock feature really appeals to me. But between the cost of the system, and the cost of getting new wheels built, I'll probably just take my chances with your method.


    After you thoroughly beta-test it, of course. :norton

    Yes. I checked them first for "tone". I assumed the wheel was "true". As necessary I will clear the affected spoke and reseal.

    No. It fit perfectly and I ran some Seal All around the rubber washer on the inside.


    That's my thought as well. I'm carrying tubes and tools to revert if necessary on the road. I left the front tubed for now also. I figured the experiment was better on the rear than front and as I've never had a front flat (knock, knock), I'm hedging my bets that I will continue to be annoyed by only the tail dragging up the debris.

    As a bonus, if nothing else, I've eliminated the need for a rim band.
