  • Idle Jet Screw

    Anyone know where I can find an Idle screw for a 78 xsE? A nearby Yamaha shop told me they're no longer in circulation due to age and I'm hurtin' for one. I'm in Dallas.

    They are kind of hard to find and expensive new, here's a carb kit that has the one you need for under $20...

    Maybe someone has a spare one for you.

      And is that the main Idle Screw? I realize theres one for each carb but isn't there a main one also?

        Do you need the large main idle adjustment screw for overall idle adjustment or are you refering to the jets?

          I may have made a mistake by adding jet. The one I'm needing is the overall idle screw or bolt whichever its called.

            They are still available, Yamaha P/N 2H7-14922-00-00. If you google that part number, you'll find several vendors. Here's one...

                No problem. I might add, many times your local Yammarobber dealer can get these old parts still, they just can't or don't want to look them up. If you have the part number, they can easily check their computer to see if it is still available. Good luck with getting your bike running.

                      I always use the UK forum site. www.benefiscal.co.uk

                      It's funny, I just did the 850 final drive mod and the FD I got had a broken vent cap. I took the number into the local dealer, and they managed to locate "The last one available anywhere" for $25. I know that if I had just gone in there and asked for the "Final drive vent cap", they would have looked at me like a deer in the headlights.

                        Hi turbo,
                        that's the single adjusting screw that sets how far all 4 carbs can close?
                        Thread an ordinary (M5?, M6?) bolt or Allen screw in there and adjust it with a wrench.
