    Carb settings for modification

    how about instead of telling everyone to figure it out for themselves, we make one huge thread that has everyone's settings in one place. So then people can have a baseline to start with, include elevation, jet size, needle position, mixture screw turns and what modifications you have for your bike.

    that sounds like a good idea :-) but i think this would have to be in some sort of a spread sheat by engine size/elevation, size/modifications/elevation

      nobody is for this? I figured it would save a majority of the posts about settings on this forum.

          I for one LOVE that idea, and have a break down of modifications to the engine. pods, exhaust ETC ETC. and keep it simple, so worked bikes shouldnt be listed. basic bolt ons ok, but not overboard to keep it somewhat manageable.

            I started a spreadsheet with the information from my GS550 manual. People can add their bikes to it if they want.

                All that information came from the Suzuki manuals that Basscliff has on his webpage. It just makes it easier to have it in one place I guess.

                  I believe there is already a spreadsheet for all the stock settings on the site. I just can't remember where I found it.

                    Where did you get that from? Your attachment is way too small to read.
