    Motor Mount Positioning?

    So I have a question about the motor mounts on a 78 GS750. I want to sort this out before the engine is sitting on a jack under the frame...

    Which way do the top rear mounts go, with the extra bar towards the frame or the engine?
    I'm talking about part #8 in this fiche: https://www.partzilla.com/catalog/su.../gs750ec/frame

    This pic should make it a bit more clear what I mean by the "extra bar"

    Does this go towards the engine, and I have this mount on the correct (left) side... or does it go towards the frame, and so this mount needs to go on the other side?

    I cant remember which way it goes but it will be apparent once the engine is in. Pretty sure the "extra bar" faces the chassis.

    Bolt up the other mounts and it will only go in one way.
    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....

      My rear mounts are situated with that piece close to the frame and not on the outside as yours is. Is it for rigidity purposes...IDK?

        Measure the distance of where it bolts to the engine. One way will be closer together than the other way.

          It may be for more thread surface area and strength.

            There isn't much thread left over on mine...not like you're gonna put a nut on it to keep it in place.

              Yup, ok. Looks like I have it backwards... Measuring between mounts this way is too much distance. Switch them around, and it's a hair tight. Gonna have to sand the powder coat down a bit where the mounts bolt up.

              As always, thanks for the help and the quick replies everybody.

                I did think it was odd that the bolts stick out so much. Judging by the part # though (01500-0840A) they should be 8mm x 40mm, which they are...
