After installing the Clarke tank w/YZ tank a few months ago I have noticed that it is starting to rub on the shock reservoir where it mounts on to the shock. I am affraid that with the weight of the tank and pressure from the seat that it could possible wear through, or atleast weaken the tank. To correct this problem I put some foam used for weather stripping on the frame in addition to the factory foam, but it does not have enough density to space the tank up enough. I am thinking of putting some rubber on the frame instead. Does this sound like a good idea? Has anyone else had this problem?
