Bringing this from the dead. I've loaded up XR/ATK 300-350 lbs bikes with slime. I mean a lot, per the instructions. Probably 16+ ounces per tune of the stuff. I do a lot of cross country riding and breaking brush, off any kind of trail and run over all kind of garbage. I've pulled tubes that had tiny green spots all over the place. Worked great for cactus, small sticks, big goat heads, etc.
by the way, it will self balance with enough of it. Same idea as ride on balancer.
