Yes Tbs not seated correctly could cause that. Though more than likely you would notice the bike sounding odd at idle as well. Just depends how bad the vacuum leak is.

Like OMR just said kleen air done right will create vacuum not pressure. The AIS system that normally hooks up to the pair valves on the top of the head, which are like unidirectional flow check valves, are an emissions thing that pulls air from the airbox and directs it to the exhaust ports of the head to help burn off some residual unspent fuel. The crankcase breather stock routes to the airbox so hot oily air is constantly entering the combustion chambers. So when you hook the crankcase breather up to the pair valves they pull all that nasty oily air to the exhaust. Also prevents oil from getting into the cylinders on a drop so you don't hydrolock the motor.
