Oil coming out of the air intake?

    Hi, someone could tell me why the oil was coming out of the air intake. This happens more often when I ride at high speeds. I already checked the level of oil and it is at the correct level. I have V&H FP3 and it is set correctly. Thanks

    solved: This problem never seems to come up in the wintertime. it is happening in the heat of the summer,  too much oil in the crankcase. Most air cooled Harleys will be happy with about 3 1/2 to 3 3/4 quarts of oil in the crankcase instead of 4 quarts. The oil heats up in the summertime and expands outward through the breather. The easiest way to check this theory out is to pull the dipstick when the bike is hot. If it has too much oil in it and is puking out the air cleaner, pull out a pint and go for a ride. When you come back, pull the dipstick again and check it out. It is an easy fix for an age old problem. On the other hand you may a a big honkin hole burned in the top of the piston and it is puking oil out of every hole it has. Not likely though.

    My Street Glide does it as well so vented to the air and a closer eye on the oil levels

    To much oil in the oil tank.
