GS750 engine swap

[origional-dz]

Just curious as to what other engine would slip into a 1977 GS750 frame? Does any other Suzuki have the same mounts?

i know that post 1980 - 750/850/1000/1100 shaft drives are all interchangable

so, it is likely your 750 frame would take a larger motor

someone here should know for sure

You can get a 1000 motor in there quite easily, though you'll have to fabricate some new bottom and rear mounting brackets (which is pretty easy). Probably be able to drop in an 1100 as well, since they swap easily with the 1000, though I've never done that one myself.

IT would take some major modification to the frame to handle a shaftie motor. The swing arm pivot is NOT the same tween the shafties and chain drives. However, a 1000 motor will drop in with only the REAR mount needing changed from what i understand.

the simplest swap would be to a GS1000E chain drive model. 1100 would be 4 valve model & require more work. You could also install a GS 850 top end for a few more hp
