Tipped my bike over on it's side yesterday. When i got home i removed the airbox cover to see if there was any oil in there. There is a hole in the bottom of the airbox. Is there supposed to be a tube or hose coming in there?. Or is it a drainage hole. 2002 Honda 350.

 

If its like mine there is a hole there with a fitting for a clear plastic cup. You remove the cup to drain out water.

 

oh...so it's the clear plastic cap about 2 and a hlf inches long...3 quarters inch diameter that you see when you look underneath the bike from behind?.....am i right?

 

yeah it is for checking the condition of the airbox without removing the lid.
