inconsistent Idle

TDAWG
I have a 81 Honda cb 750 custom.  I have a some changes to the engine. 1. I got rid of the air box, 2. I added individual Carbs air filters, 3. I also have a 4 into 1 drag pipe on it.  At one point it ran really nice like this.  I was really proud of it. It sat for a while, but it still runs.  I made a mistake, I added a baffel and changed the jets, to make it quieter.  Bad move, it ran like crap.  I put the old jets back in took out the baffles and now it runs ok.  My problems is this: I start it with the choke on, push the choke off and it just barley runs.  I ride it and the idle goes through the roof.  I turn down the idle screw and it almost goes off, I ride it and it screams again, then on its own comes back down to a low idle then almost cuts off.  I have to hold the throttle open to keep it running.

someone please help me.  Please!

It sounds like you have air leaks around the manifold rubbers. Get it running and spray some wd-40 around the manifolds and listen for idle changes. Your issue sounds like classic air leaks making the mix really lean and having idle issues.
The ride IS the adventure. The destination is just to get gas!
