    Are these OK??

    I pulled out the pilot fuel screws because I was reading that they are supposed to be sharp. Mine have very distinct blunt ends.

    I uploaded some photos in hopes that you would be able to tell.

    I have a 78 GS750E.







    TIA for the help!

    The tips are broken off. Check the carb bodies, the tips may still be stuck in there. Check this thread for info on how to check the carb bodies. http://www.thegsresources.com/_forum...ad.php?t=82559

    Those screws are hard to come by. Only way I know to get them is in K&L carb rebuild kits (Z1 Enterprises sells them). If you have the tools you may be able to sharpen them on a lathe.

      Would that be the cause of my high idle?

          I redid all the o-rings and dipped and stuff, but I had no idea the little jets n things could break.

          Are there any other components in the carbs I should check more closely?

            Change the intake boot O-rings while the carbs are off if you haven't already. False air from the boots is very common and will cause a high idle.

              To resharpen mine I clamped the screw into a drill then put a dremel with a sharpening stone into a vice and spun both while lightly touching the screw to the stone... Worked pretty well

              The one on the far right came out way too short because I made the stone go into the screw instead of away from it.

                I did change those as well by recommendation of the forum .

                Am I better off reshaping these ones or buying new ones? The PO put on pods and I don't even know if he rejetted.

                  I think 1978 750s had 102.5 mains and 15 pilots stock, what do you have?

                    Is it written on the jets somewhere? How can I tell?

                      It should be written on the jets, provided they arent too badly pitted.

                        Should the jet needle be sharp as well??

                          No, they are usually blunt.

                            Well! Today I discovered the broken off pieces. Dang those holes are small! I would never have found that without this forum.

                            Next step - find a sharp something to get them out. I don't have an awl, so I'm gonna get creative.

                              A piece of stiff wire might push them out. Sewing needle maybe? You can get a carpet needle that is curved. Straight pin held with needle nose pliers. Just be careful not to enlarge the holes.
