    Substitute Stator for my GS1100G

    Hi all, Looks like my GS1100G stator has lost its oomph (still need to carry out a couple of checks to be absolutely sure).

    I have a spare cover and stator from a GS1100ES (at least I think it is as the covers are much the same except it has an extra bolt hole at the bottom front edge). However I don't know if it is off an ES D or an ES Z.

    I have done some part number cross referencing to see if they are compatible and see that although the GS1100 ES model D Sku is different to that of the GS1100G, they appear to both superceed the same part on the XN85. However the ES model Z does not share the same commonality with the GS1100G.

    Considering the above, I am assuming that if my spare part is from the GS1100 ES model D, that there is a better than even chance that the stator will fit my GS1100G... but am not sure. I am also unsure if the GS1100 ES model Z stator will fit.

    Is there anyone out there with any experience with substitutions that can confirm whether the stator can be swapped?

    Thanks

      both bikes have the larger stator so i would guess that they would interchange.

              Hi,

              According to Electrosport, they sell one part, the same part, to fit all of these bikes. The only difference in the OEM part numbers would be referencing the connectors or rubber grommet that fits in to cover.

                  I used to have an 850G. I ended up replacing both the stator and the r/r with Electrex (now Electrosport) units. Never had a problem with it after that. The r/r went south on my current 450, so again replaced it with an Electrex unit, and again, so far, I haven't had any problems with battery charging since then. I'm not sure about the 1100, my 81 850 had big Phillips head screws for the stator cover, I believe the later GS models had regular hex head screws. I replaced the screws on the 850 and the 450 with socket head cap screws (use an Allen or hex wrench). Whatever you do, don't use a screwdriver to pry the cover off. The magnetic force from the stator is significant. It's not a terribly hard job.

                      Awesome. Thanks everyone. Checking the two different models at the electrosport site shows that they share the same replacement part number "ESG020" so as Basscliff indicated, I may have to swap rubber grommet and connectors. I'll give it a go then.

                      Gosh it's tempting to order up a new one at $119 (though out of stock.. lol) and a rectifier at $99.

                      Thanks again
