Do me a favor. Go start your bike and let it run for about a minute. Turn it off then open your oil filler cap/dip stick. Can you hear a sucking/suction sound?


I put my krank vent back on this afternoon and checked the oil. I heard a suction sound opening the oil filler cap. Just wondering if it's normal.

Are you immediately opening the oil fill cap after shut-down? I usually wait about a minute before removing my cap and have not heard the suction sound with my krank vent. I do remember that other people have heard the same thing that you are hearing because of the vacuum in the engine caused by the krank vent. As far as I know this is normal.

Ya, I open it a few seconds after I shut her off.
