    Can someone confirm this is the tool I need

    Time to check valves again .. they were fine last I checked but that was 4200 miles ago. I want to have the tool on hand should i need to do it.

    I cant rightly remember but I am pretty sure the adjustment screw was Square and the locknut is 9mm. I have an 82 16v GS 750E.

    This is the right one .. Right?

    Or you can make one out of a square drive wood screw screwed into a piece of dowel, and a 9mm wrench.

    here's another idea. You could grind a slot into something like this.

        If I remember correctly the adjuster has a standard slot on it for a straight screwdriver not a square. The locknut I'm pretty sure is 9mm though.

          1981 GS750L - Owned since 1990 when graduated high school and since have been discovering all the things not disclosed by seller.
          1983 GS750E - bought in 2016 as a rough runner to use while rebuilding 81L and then to combine with ES to make one good one
          1983 GS750ES - bought in Toronto in 2015 on a lark as a non-runner, missing front cowling and exhaust - If you have a 1983 750ES front cowling let me know! Blue would be nice

            If I didnt want to wait 6 weeks for delivery I might try them but ... I do love this from the ad !!

            I just picture a guy holding up a ruler and squinting and going Hmmmmmm yea that looks about right!

                Thanks everyone but I don't need a set. I just have the one bike. I just can't remember if the adjustment screw is square. I am trying to avoid taking the bike apart and then ordering the tool because then I will be down a week and it's my only way of getting around.

                  Just for anyone else that may come along

                  I did buy this tool
                  Motion Pro Tappet Adjuster (3mm Square with 9mm Socket)

                  https://www.amazon.com/gp/product/B00T6JO4EY/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

                  I also bought a small set of Motion Pro Tappet feeler gauges.

                  I landed up only having one valve that was tight and that needed adjusting and all the others were in spec but man .. it was really nice having the right tools!! The last time I did the valve check about 4000 miles ago I used regular feeler gauges but the short bend on the Motion pro feelers gave me a big confidence boost. With the regular flat blades I felt " yea that is kinda maybe right" but with the short angles Motion pro feelers you know you are dead on.

                  The adjustment tool was a dream and worth the 18 bucks.

                    Just a word of caution on the feeler gauges, they are thin and will eventually tear apart, I know this.
