Another newbie question: Seepage on carb/airbox connection

[Jay96B6]

I noticed that the connection between the air box and one of the carburetor has some seepage. First, I am new to the carbureted engine, so I don't know why oil would leak back to the air box. Second, only the second connection from the throttle side has seepage, the other three connections are bone dry. Should I worry about it? Thanks!

Hey Jay

The crankcase breather connects to the airbox, so the airbox can collect some oil, and needs to be drained occasionally.

There is a drain hose that discharges by the right footpeg, that has a drain plug clipped on. Remove this plug, drain the accumulated oil and water, then make sure you plug the hose again, as this hose connects to the "clean air" side of the filter, and you don't want to suck dirty air.
