    GSX engine in a GS frame?

    Simple straight forward swap or is it more to it?

    I'm guessing new engine mounts need to be fabbed?

    I might have a deal going on a cheap 84 or 85' gsx1100.... Want the GS1000 or 1100 engine but they're not easy to come by here and especially not one with a chain drive so looking in to this as an alternative....

    If you mean the 1135 motor into the 1074 chassis then it's a straight swap - same engine mounts.

    You need different bottom motor mounts if you are putting an 1135 or 1074 motor in a 750 chassis.
    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....

        It might be easier to put an old air/oil cooled 87 to 90 GSXR1100 motor in it they are a lot smaller and lighter Bandit 1200 motors can be bought for around $1000 to $400 depending on condition

          It's do-able. Quick and dirty way is just to not run the under crankcase mounts. If you've got the time it's quite easy to fab up new ones though.

            Actually I'm not running the under crankcase mounts now as I couldn't find the correct bolts

            But the front and rear mounts line up?

            What's heaviest of the 8v or the 16v?

            The 8v 1000 is a straight bolt-in affair?

              8 valve motor is lighter than the 16 valve

                  "lighter" being a relative term
