My bike at low speeds has been surging, even at idle it was slightly erratic I had a guess it might have been fuel filter, bit surprised at the crud at the bottom of the pump housing, mostly a rusty paste. I've had the housing soaking in evaporate to clean it up, was thinking about sealing the bottom with a tank sealer to stop any further rusting. With a new filter in I'm looking forward to a clean ride again. Bike is nearly 95000klm is it common for the housing to rust like this?
