      It's definitely cam walk.

      There are others on this forum who have done this machining. Hopefully, one of them will listen to your clip and confirm that you have cam walk!

      I was skeptical too until I removed the cam chain and slid the cams sideways back and forward against the thrust rings. The sound I got was identical to the knock I was hearing, but with less magnitude because the cam cover was removed.

      I can appreciate your skepticism on this, as you are receiving a lot of contradictory information.

      Keep riding it. If I'm right, the sound will still be there in 6 months or even 6 years time, and no further damage will have been done to the engine.

        The thing I can't square with the cam end float noise is that it only makes that noise when cold and it disappears when hot. That's the other way round to norm.

          Yeh , thats whats bothering me, tried it again tonight before i came in from the worshop just to let a biker mate of mine have a listen over the phone, i told him to listen for it 2/3 minutes , after start up and then listen again when its at full temp , and sure enough it came and went again, so to be honest i think i,ll get the carbs done and take out the tensioner and refurb that and re-set it and who knows, it might even sort the problem out as that would stop a lot of lash too, we,ll see, as for the fuel tap , it think it would be wise to fit a new pet cock while doing everything else too, cheers jon




          Also, ive been offered a low mileage gs650gt head and with tight cams for Ł195 plus postage, what you reckon, its off a breaker on ebay
          And what is the measurements to check for on end float, i mean what is the float allowed to be

            I don't think Suzuki give a figure but Ian reckons 0.0015 in (and he sorted it).

            have you got a link to the Ebay item. There's one or two dodgy breakers we know out there.

                  I never noticed it when the engine was cold, unless I left the bike on the side stand the last time I parked it.

                  I believe it's related to excessive cam bearing clearances, and the viscosity of the oil at idle. I never noticed the noise directly after hammering the engine. I could stop and no audible knocks for some time until the engine cooled or the oil viscosity/pressure dropped.

                    My GS650E had exactly the same noise when cold. Since I had to remove head for gasket, I had to take the cam chain tensionner off, When I replaced everything and adjust properly noise was gone. Just my 2 cents.

                    Good luck.

                      Not a cam walk, not a tensioner. It is a single noisy cam chain link, going over the two sprockets. Listen to the timing of it, click, click,,,,,,,,,,,click, click,,,,,,,,,,click, click,,,,,,,,,,click, click, once every several crankshaft revolutions as the chain link goes around. The noise will be there for a while then go away for a while, usually it's only with a hot engine, and only at idle. You can't hear it at any higher RPM. I have heard this on two previous GS engines, one an early 750, the other I think was a 550. Both are still running fine, and have not failed. You couldn't see or feel any damage to any one link when the tension was loosened, no kinking or anything. If you run the engine at a slow idle with the valve cover off the cause of the sound is very obvious. We put a spot of paint on one link, the timing of the noise is perfect, the same link was making the noise every time around.

                        Hell allof these theories are sounding honourable too, i guess when the carbs come off and i can have a look at the tensioner it might as well be a good idea to take the cam cover off and have a look inside and take some details , this is one hell of a forum , cheers guys..respect

                          It's hard to run the engine with the carbs off.

                              Where did I mention I was going to run the engine ???? read the post again, it states. "when the carbs come off and i can have a look at the tensioner it might as well be a good idea to take the cam cover off and have a look inside and take some details" unquote !! I mean't take measurements of cam end float, cam chain condition and wear etc etc.....Strewth

                                Sounds like a lot of unnecessary work.
