    He got bigger problems that an inline fuel filter Dan.. Did you read about him having to remove chunks from the petcock twice in 3 months??. Theres way more going on than aninline filter!!!!I have had GSs WITH an inline and thats a bunch of bullpucky.....they ran just fine and no differences. The amount of fuel being used by the engine is WAY WAY less than the flow that goes thru 2 inlines at a time unless they are plugged. You guys can haggle over that as long as you want and call me on it till your blue in the face..its an outright lie!! I have had them in my bikes and they have never so much as had a hickup because of anything other than one getting plugged up after a few yaers of use. AND just where in anything he posted does he mention an inline fuel filter..did you read anything or just grabbing at straws???? If oyu have the old paper media filters then yes i can agree with your point. The modern ones with the nylon screens like the tank filter on the petcock are deisned to trap CHUNKS and are designed to be in gravity feed systems. The paper media ones on the other side are designed to be used in a fuel pump PRESSUREised sytme.. So to blanketly say an inline filter causes reduced fuel flow is not true.

      I'll give it all a go tomorrow. I might send carbs off to a friend to sort out, I really don't have a clue about them. I cleaned the bowls, pulled out some pointed thing (Jet?) and cleaned the brass parts with holes in.
      No idea what to measure...I guess the brass tube around the pointed needle thing? I sound ditsy as.

        You will measure the INSIDE diameter of the carbs throat on the engine side of the carbs..thats the MM measurement you need to know. You also mentioned that it seems to run fine on 2 and not all 4 cylinders. Did you pull each plug and crank it to be sure all 4 plugs fire and make a spark? There are 2 ignition coils. One coil fires the the 1 and 4 cylinders ( the two outboard ones) and one fire 2 and 3 ( two inboard cyliders) Which two pipes get hottest and which ones stay cool?

          I will measure them tomorrow and post on here for ya. Thanks for all the info.
          Just found out the points are sparking / arcing. I think I set them up right and the turn over too but still sparking. Condensor gone me thinks.

            POINT GAP is supposed to be .035 SAE measurements. If they open too much they will spark very noticeably. EDIT>> Corecting this post..i meant .35 mm which is .018 SAE
