Bike bogs down and dies after reving up to 5k RPM

Never, ever do this with any vehicle

Amen! sure to cause voltage spike as no reference point for charging system.
Mak: this is not a choke system with a plate that blocks carb intakes- it's a fuel enrichment system that allows extra fuel into intake manifold. If bike runs poorly with this off, it means you're getting too little fuel or too much air- as others have said, check airbox for tightness.

On newer vehicles with computers this will fry them.

I'm out of state right now (being a truck driver and all) but as soon as I get back home, I am planning to take off the carbs, checking the sync on them again and throwing the airbox on. Thanks for caution about the battery disconnect.

All the maintenance suggested is needed but just for curiosity's sake, I would properly install the airbox and try it. It would probably run way better. Then you could go on to take care of all the other issues with spirits buoyed.
