A main sponsor and contributor here is at the top of the page. His website under " blog/tech" has just about everything you need to know. I will point you to this page:

He's kind of the Bible here on GLs
Assuming you meant 769, you should be fine to swap complete racks. Scroll down and you can see the jetting and parts differences.

Looking at it again, if one set is running well and clean, the only differences are in the primary air jets and idle air jets. The other parts are all the same.

769A's are pre emission. 771A's are emission carbs. Any of the 1000 or the 1100 carbs will swap. Performance may change a bit.
Please, go to the intro section and tell us a bit about you and your bike.
