Not familiar with the 1000, a couple things come to mind though.

Did you do a bench sync and verify throttle plates were working together correctly before install or possible linkage problem being installed backwards, upside down etc.

Leaning the bike over and having it stall tells me floats are out of adjust. Doing a running sync on questionable carbs gets you nowhere fast. High idle would be due to plugged/open passages in one or more carbs sucking in air and fuel from circuits that are not supposed to be active.

Do a bench sync using a strip of business card paper. If the engine will not run that way it will allow you to diagnose carb troubles on a level playing field. Jacking sync screws to get one carb to carry the load might give quick results but is not correct.
