    Pmed you


    Can they be inconsistent, sometimes I have a smooth reaction to throttle, sometimes it fights to go up. Would that indicate anything?

      Yes! they can be inconsistent but so can other issues.
      Fitting fresh plungers may or may not fully cure the problem but it will permanently eliminate them as the cause of any current or future fueling fluctuations.

        Your hanging idle issue may be related to the timing advance. Many here have had the same issue with a rotor slipping or other part not operating as it should.
        I'm not familiar with your model but as an example, I installed a Martek ignition on my '79 1000 back in 1980 to replace the points. The Martek rotor had a set screw to keep it tight. The set screw came loose and the bike behaved exactly as you describe. I'd check everything and verify correct operation with a timing tool.
        And on the seventh day,after resting from all that he had done,God went for a ride on his GS!
        Upon seeing that it was good, he went out again on his ZX14! But just a little bit faster!

          If pulling the choke rack can get it back down could it still be that?

          Bikes apart right now could check it, when i did a few months back it corresponded fine but I just used a timing light making sure it moved, not if it was tight. Probably gonna inspect it later while I'm putting the bike back together

            Using the choke, on a fully warmed up/hot engine, will lower the rpm's or stall the engine, depending on how much choke is used. It's normal.

              What exactly am I messing with on here, is it something right on this surface or behind all of it, and ifso i know these screws won't budge easily I don't think any of this has been messed with.

                    Okay so I found what moves the advance on the outside, I been pushing it and letting it fall back seeing I'd it sticks and so far no sticking, the piece itself has play I can pull and push it back and forth but not rotate the advance freely, and it has the tiniest play in rotation but that doesnt move the advance.

                      Your finger is pointing at the little tab on advance mechanism....grab it...it should rotate easily about 30 degrees and spring back when released.

                        It does, so I guess back to vacuum leak, which i hopefully took care of the problem if it's the intake boots.
