I am considering installing some 750 oil pump gears in my new project, a '78 GS1000, bored to 1085, ported head, VM29's, aftermarket cams. The questions are: from which model 750 do I get the gears from? Is it just a straight replacement, i.e. take out my gears and put the new ones on? What all else do I need to do? I know I will get an increase in oil flow volume, but will the oil pressure also be increased? If so, by how much? Any other mods I need to do to the engine to compensate for the change?

There from the same year as ure im pretty sure. Cant go wrong as the gears are phyically larger/smaller than yours. Have u seen the GS1000st parts book post ive done on here.

You can use the gears from the 8-valve 750 motor or from the 16-valve 750 motor from 1980 through 1982. You must use a set, not just one gear.

May notice a small increase in pressure, it is more about volume though. Is particulaly useful if you intend to run an oil cooler and or a topend oiler kit.

One gear is attached behind the clutch, the other is on the oil pump shaft.Comment

You got OEM 750 pump gears in some fancy Schnitz packaging is what you got...
Bruce, it doesnt matter. The ratio on the 8v 750 and the 16v 750 is the same. There is a difference in LOOK (casting marks are a little different) but they make no difference whatsoever. I have both, have used both, no difference.
On the other side of this, are you sure they're any different than the 1000s?? Im not sure on that myself...Comment
