Many motorcycles come form the factory with some type of sealant at the air hose to air box connection. It is important that there are no obvious leaks at this connection.
Not only do you not want water or dirt entering the air stream at this point, the intake system/carburetor is tuned for the intake to be in place and tight. All of it. Air leaks at this point can contribute to poor engine performance.
You woke me up, for this???
