Parts Interchangabilty

[limeex2]

Parts interchangability. Sorry if I have asked this question before, but does an exhaust systems off of a 81 GS850 standard fit on a 78 GS1000? Also, do carb assy's from a 93 GSX1100G fit air cooled 4v 1100"s? I know GSXR750 carbs bolt up to a 4V 1100. The GSX1100G has flat slide carbs, once again, I can get the whole bike really cheap.

Dang, I'm scratching the murky bug-infested backwaters of my mind, and I remember that I had a nice '79 GS850 exhaust from a freebie bike, and a '79 GS1000E with a 4:1 header that was rusty. I fitted the GS850 system up and all was good. The 850's mufflers were a few inches shorter but the whole setup aligned with the mounts. Heck, I was so surprised and pleased that I took pictures of it and even posted here, I think.

So, given the difference in years I'm talking about, that narrows the question down to:

(1) What's the diff between the 78 and 79 GS1000? Nothing, from what I can see on Partzilla.
(2) What's the diff from the 79 and 81 GS850G? Nothing again. But double-check the Partzilla #'s.

Man, I was waiting for this question to come up haha

That is awesome! I love that even with a longshot question like that, someone around here has an answer.

I somehow had the impression that 750/850 was a go but the 1000 was wider and 850/1000 would not go.
Just as well I kept my mouth shut

This is great info. I have a bone stock 78 GS1000, very good shape, but the exhaust head pipes are so rusty the pipes cant even be re-chromed(I dont believe). Want to restore it, but keep it stock. I've modded every bike I've ever owned. Now the auction the bike I was looking the bike is and gone. 850's seem to pop up for sale usually pretty cheap. If I'm patient I find one. Thanks guys!

Bummer you missed out on that bike. If it's just the exhaust you need, I've got a pretty nice set from a'79 850. Here in NM things don't tend to rust out like up there. This set could use some evaporust and polish, but should shine up nicely. There are some scratches that won't buff out, fyi. PM me if you're interested.
