    Skunk Clutch rattle

    It's always made some noise/vibration but has started to get worse. I've put 3k miles on the bike since I put it back on the road. Goes away when I pull the clutch lever in.
    The 1000G is much smoother.

    I will first check the hub nut is tight (do I need a tool for that or can I do it in gear & what size socket is it?) I did check it when I checked the plates etc before it went back on the road, was tight then.

    Other than that I assume it's probably springs/rivets/balance on the clutch basket?

    If so the cure I think is a welded clutch basket? Any recommendations / idea of $$? Can I use stock plates & fibres?

    Cheers,

    Dan

      Schnitz is a little cheaper

      These are all for the 1100 so you need to make sure it works for the 1000; APE has added the 1000 as litings to their standard 1100/1150 parts listings.

              Ray,

              Will give you a shout tomorrow.

              I need to get inside there first & have a look at what's going on I guess, other than the vibration & increased noise it runs great, don't notice it when moving.

                Dan,

                Have you checked your carb sync lately? Poor synchronization will give an uneven idle which can cause clutch rattle..................

                  Nope, not checked it since the day after it went back on the road.... Would 3k be enough to upset things?
                  It's been worse since I've been running less......

                    Dan,

                    It's difficult to judge by mileage. Any change in intake (dirty filter, intake leak, etc.) could affect the sync. It's easier to check than pulling the clutch apart. You'll also probably notice it more in cooler weather. Mine has a noticeable rattle when it is cold but it pretty much disappears once it warms up and the idle evens out.

                    Thanks,
                    Joe

                      I will say this much, my big nut was loose on the first go around, so I pulled everything and discovered that the big springs were a tad loose in the back, but the smaller springs were fine. So, I put a new OEM nut on and washer (I went cheap), built a tool and torqued to spec.

                      With the big springs loose it does not rattle. Maybe by the time it gets to 34 it will.

                      I have seen both sides of the argument for welded vs. new OEM. I guess the new OEM's are updated.

                      I also bought a spare basket/gear so that if I happen have 300 dollars laying around with nothing better to do, I could send it off to be re-springed and welded.

                      I would probably go with the OEM unit seeing that mine is a GL and I am not out doing crazy stuff or putting down modified E horsepower.

                        I just replaced my 1150 HD clutch basket and found the basket rocking on the gear. It's 12 years old. I too thought my noise was coming from the clutch. I put a unmolested used HD basket and new inner clutch hub in and the noise and ruckus are still there. I do have the Ape nut.

                        It sounds like a turbo cummins diesel at idle or a Ducati with a dry clutch.

                        Maybe my roller bearings on the crank are on the way out?
                        GS\'s since 1982: 55OMZ, 550ES, 750ET, (2) 1100ET\'s, 1100S, 1150ES. Current ride is an 83 Katana. Wifes bike is an 84 GS 1150ES

                          I had rattles in my old 750EF and 1150EF which both went away over 1500 RPM. So I just put my idle up to 1500. Problem solved
                          Current:
                          Z1300A5 Locomotive (swapped my Intruder for it), GS450 Cafe Project (might never finish it....), XT500 Commuter (I know - it's a Yamaha :eek:)

                          Past:
                          VL1500 Intruder (swapped for Z1300), ZX9R Streetfighter (lets face it - too fast....), 1984 GSX750EF, 1984 GSX1100EF (AKA GS1150)
                          And a bunch of other crap Yamahas....

                            carter,
                            call me.
                            i may be able to shed some light on the (rattle) at idle that goes away when you roll the throttle up.
