    BBSHD leaking after a hot ride

    Yesterday I went for a 15 mile trail ride when the temperature was in the 80's. By the time I finished it was over 90. Today I saw a puddle under my bike and signs of leakage on the motor. I have the motor lubed with Mobile 28 grease. Would overheating cause the grease to liquify and leak? Is it possible that oil/grease got into the controller and is that a problem? The motor runs fine and is quiet.

    Mobile 28 is aircraft rated and doesn't start to loose its consistency until over 500°. I think you need to look for another answer.

      Were you frugal or overly generous with the grease? Is it watery?

      No matter - you should open it up!

        If it's a lube of some kind, it looks more like shock / suspension oil to me. No leaky dogs or humans nearby I hope.

        Has the puddle evaporated?

          It's shock oil! Boy am I embarrassed. I rolled the bike out of the shadows and flipped it over to take off the back wheel and saw the oil on the motor. I panicked, saw the puddle, took photos and posted a motor problem. The motor is fine, but I'm going to be rebuilding my rear shock. Thanks everyone for quick replies.

            I didn't think there was that much Fox Float Fluid in that shock. There must be none in it now.

            The stuff spreads really thin and all the pressure will push most of it out when the seals go south - don't get it on your disk brakes!!!

            The shock internal seals are blown, and the cost to rebuild equals the price of a new shock. Even if it can be repaired it won't be reliable. Time to go shopping.
