    1978 GS 750e tachometer cable

    Sorry if i'm posting this in the wrong area, but when I purchased my motorcycle the tach didn't have a connected cable, but the person who I purchased it from said he had the cable and gave it to me. It doesn't fit right into the cam cover, it seems to be too loose, and we checked on his bike too (same bike). His cable also didn't fit (second cable). Anyways I'm looking to buy another one but I do not know where to go for this, or if there is suppose to be an adapter that I'm not aware of.

    It sits loose inside the cam cover like attempting to screw a m8 bolt into a m10 hole. I think it's the same size as the speedometer cable.

    Thanks

    Take a look at the parts diagram for the cylinder head http://www.partsoutlaw.com/oemparts/a/suz/50d3fec1f8700230d8b4dc9a/cylinder-head. Are you missing any pieces at the end of the tach cable (25-28)? There's only one part that can screw into the head.

    The fact that you tried two cables, one that you saw fit on another GS750, suggests the tach drive hole on your motor might be damaged. Not sure how this could happen.

      Its possible that that I'm missing a piece. The gear is there I saw it when I adjusted the shims.

      I have everything from 25, 26, 27. I'm not too sure about 28. Is that suppose to connect to the cable or is it already on it. That might be the thing I'm missing. I'll post a picture later when I get off work.

      Thanks for the reply!

        #28 is the inside seal. Look at your cable ends where it screws in, what do they look like.

New SS fasteners through out. Rebuilt carbs, new EBC clutch springs and horn installed. New paint. Motor runs strong.

          Yes I realized that after I posted my comment that #28 was the seal. It appears to be there.

          I took some pictures of the cable and the inlet on the engine. It looks like the cable fits but it is actually too small to thread it. I may have exaggerated on how loose it was (I was going off of memory), but It still doesn't fit.

            Are the thread good inside the gear drive assembly???? They may be so stripped its just slopping around.

            I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

              From that pic, it looks like #26 will screw into the head but the cable won't screw into #26?

                Correct, It doesn't screw in, and the threads are not stripped out unless something happened to the cable ones, and they're suppose to be way more defined than they are now.

                  I've been looking around online and it is possible that I just have a second speedometer cable. Looking closer it I think that's the problem. I'm gonna drop a couple dollars and see if a new one will fit. Thanks for all the help fellas!
