If she is as good looking in the flesh as she is in the photo I would start with another bike. Plenty of cheap 750s out there to upgrade.

Thanks for the info guys

eric, any pointers with regards to fitting the 1000 engine?

Picture of my starting point

That's a beautiful bike, I'd use another and keep that one intact.

Buy the front engine mounts (used will work) for a GS1000 of '79-79 vintage as you will need to modify (drill one hole in each) and
a right side foot rest from the same vintage bike as the engine would run into the stock right side mount on your 750.

Thanks for all the help guys, my 750 is a really clean bike and im in two minds about leaving it standard, may buy a tatty 1000 to use as the basis of the project. It will atleast save the extra work of swopping engines. decisions decisions

Sounds like you want to build a "sleeper" which I consider to be a very high performance bike that looks like it won't make it around the corner without breaking down. Makes the other guy wonder "what happened?" when you leave him in the dust.
Seriously, that 750 is really nice and a great bike to boot. Do believe it was the first of the GS series and the predecessor to the GS1000. Anything you do to it will hurt it's value should you modify it in any way.
There are so many "rat" bikes out there that you can get for a song that would fit the bill for cheap, easy, high performance project. Maybe Eric will sell his!

You hit the nail on the head there sedelen, high perfomance gs but without losing the style of the standard bike,
Just subtle mods that wouldnt stand out to the untrained eye :-)
