Thanks thats very helpful. I'm not trying to magically make the problem go away but as you put it, find the problem faster.
My fz1 has small velocity stacks that came with the filter kit. It's not enough if a problem to bother me right now and the cbr runs well enough that this might be a month or two before I get to it.
We're not out here to rough it. We're here to smooth it. Things are rough enough in town.
