I'm posting this question in general as it doesn't apply to any specific brand or bike and apologize if this has been brought up before. I have noticed that many manufacturers install a fuel shut off valve ( usually on or near the tank) and then a fuel filter ( somewhere near the carb). I'm confused by this as it would make more sense to me to install the filter then the fuel shut off so that draining the carb doesn't have to involve draining the filter and line also. any thoughts?

Usually what deteriorates is the inside of the FUEL hose so you would want the fuel filter between the carb and the shutoff valve or petcock or fuel pump (closer to the carb). What you want to protect is pieces of hose getting into the carbs bowl which would clog the tiny holes in the jets and the passages as well. That little bit of fuel in the hose and fuel filter is maybe 1 oz of fuel at most and not worth worrying about having to drain that little bit more. Actually it will come out before you even know it.
