It won't be long and the fuel filter will show up on my 'to do' list. So I took a look at the service manual. I can't be certain without taking the thing apart but looks like that filter is ahead of the fuel pump. It therefore protects the pump as well as everything down stream. If that's correct, the adding of a down stream filter isn't going to cut maintenance, it's going to add to it. According to one thread (a couple of months back) pulling the tank isn't a big deal, and that's a big percentage of the job. While the tank is off the plugs can be inspected and air filter dealt with. I need to check the manual but seems as though 17,000 miles is the time to check valve lash. Valve lash adjustment is the little dumplin' that really looks to be a big deal. I don't think that can be done without removing the tank and changes to clearances are made by changing (shim in bucket) shims. It isn't rocket science but there is a lot of opportunity to really screw-up... From what I've read most engines get past the first valve lash inspection without adjustment but even so that's another opportunity to check the fuel and filters.
From what I hear filter changes on some bikes can be a lot worse than the DL's --- ask a GL1800 owner what's involved in changing an air cleaner element... :shock:
