GS750E motor parts compatability

[rodneya]

I recently bought a 83 750e motor sight unseen. I was told it was an 1100, but it was cheap.

Are there any parts from this that can be used on a GSX1100 or 1150EF motor?. I know the valve covers are the same.

There is a lot of info that I can find regarding oil cooled parts comparability, but not air cooled.

Oil pump gears come to mind.

I see part of the frame was left on that engine.  Go get the welder; it's project time.
