Run the bike...

If it was air, your bike would have a lean surge, not a bog....

 

There are a ton of things that can cause a low end bog.

 

Wrong pilot jet/air screw

Dirty pilot jet

Clogged air filter

Old gas/oil

Old/fouled spark plugs...

Left Carb is getting good flow, right has the air pocket... could it be float?

i have that same problem. i think its due to different things but mainly i think its the way my fuel line curves around the boost bottle that stops any bubbles from traveling up out of the line. lately i been straightening the line till the bubble floats up out of the line then its good for awhile. Could be several things in your case though. maybe a partialy clogged petcock or something

turn the gas off. pull the hose off your right carb. turn gas on. shove hose back on real fast.. ive had air bubbles in mine before that just wont come out. doing the above will fix it.
