    Steering Stem Removal

    I'm finally getting around to working on my GS750. I have a Gs1100 frame, gs750 forks and triples. now I couldn't get bearings that fit the gs750 forks and gs1100 neck. so I decided to do a simple stem swap and use the gs1100 stem in the gs 750 triples and voila!! easy enough.

    But it actually is not. It looks like the gs stem is actually welded to the triple. On both the 750 and 1100 lowers. So my question is how do i remove the stems without destroying the stems and lowers?

      The stems are press fit in the lower triple.

      Need a press and spacers or socket or blocks to press the stem out the bottom of the triple since its tapered wider toward the base.

          You'll need to remove any welds at the base of the stem before you try and press it out (if they are welded - I remember my 450 stem was welded).

          If you have access to a large enough lathe you might be able to spin up the stem and remove the weld that way. Obviously you will have to re-weld the stem back into the new triple after you swap them.
          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....

              just grind off any welds, when refitting you could reweld it or simply drill and pin it. you dont really need either if it is a good tight fit in the tree
              1978 GS1085.

              Just remember, an opinion without 3.14 is just an onion!

                  okay cool. thanks guys. I've done a stem swap before on my GSXR but that stem wasn't welded. I just didn't know of any special way to get it out of just grind it down. So Ill grind it down today and see how that works.

                      Are the same year models? I just did a swap on my 80 GS750E using its big brother (80-GS1100E) triple trees. bearings are the same, only difference between the two was the fork tube diameter.

                          nope. It's a 78 750. bearing's are different sizes. the bottom one mostly. I think the top one was fine. direct swap i believe.

                              I believe all balls has a conversion bearing kit to convert loose ball bearings to tapered rollers which will then allow you to use the 1100 stuff directly
