    Katana Stator cover

    My recent project bike is an '83 Kat 1100 that has a different style of stator cover compared to my same year GS1100's. Seems more protruding.

    I though the motors in both models were essentially the same but can anyone clarify?.

        I'm not positive about this but I believe the Katanas had a smaller diameter rotor than the other engines. BikeBandit shows different part numbers for both the rotors and covers.

        Thanks,

          That is an 1150 cover! They work just fine. Same internally, gasket, function, just a different look outside. If you want an 1100 cover, I will trade you if there is no damage to yours. Ray.

            Ray nailed it.

            GS1150 cover.

            Additionally, the Katana had a slightly smaller-diameter alternator rotor than the earlier GS1100's. Thus, a smaller stator as well, with a different diameter stator-mounting boss in the cover.

            If you decide to switch to the 'GS1100-syle' cover, be sure get a cover that matches your stator. They look identical on the outside (well, not counting the cover color, black vs. brushed aluminum).

            I learned about this the hard way. Hope it helps.

              If he has an 1150 cover the 1100 cover will work with the stator he has. Ray.
