VENTED DIPSTICKS FOR HARLEY-DAVIDSON

FEULING OIL PUMP CORP. VENTED DIPSTICKS FOR HARLEY-DAVIDSON 2009 DIPSTICK VENTED BLK 06+TC Billet dipsticks vent/breathe excessive crank case pressure from the oil tank through a PVC style breather consisting of an oil separator system, perforated disc, replaceable filter element and umbrella flapper valve

Screws into the factory oil fill spout as a stock replacement part

These breathing dipsticks remove unwanted build-up of blow by pressure, all internal combustion engines have a certain amount of blow by

Larger cubic inch, worn and or loose ring clearance as well as engines pushed to their limits generally have increased blow by

Blow by is pressure that is forced past the rings and cylinders, pushed into the crankcase and then forced back into the oil tank

Dipsticks help remove this unwanted pressure through a (CVS) Crankcase Ventilation System

Feuling test results show a decrease in engine oil sump levels, more freely/smoother revving engine, increased MPG and decreased blow-by

Dipsticks vent/breath excessive crank case pressure from the oil tank through a breather system consisting of a oil separator system, perforated disc, replaceable filter element and umbrella flapper valve

Includes two venting styles options to choose from when installing the dipstick

Option 1: 1/8​" NPT breather vent fitting with internal porous filter element (this option gives a clean look, however it can produce an oil misting/residue out of the element on engines with excessive leakdown/blow by)

Option 2: Quick-disconnect coupler fitting with rubber hose and filter element (this option will run any excessive oil misting/residue through the line and into the filter element, however this option does requires disconnecting the fitting in order to check the oil

Option 2 is Feuling's preferred option as it breaths more than Option 1

For Option 2, Feuling recommends routing the line up the frame rail, up under the seat/abs area then back down along the right side frame rail and the filter element can fit cleanly between the engine/trans matting area on the inside of the lower right frame rail

Checking oil level: There are two ways to read the oil level with this dipstick, with the bike on the jiffy stand (FHS) or the bike upright and level (FHU)

FHS = FULL HOT STAND: if reading the dipstick with the bike on the jiffy stand you will take your reading from the dimples labeled FHS (Full Hot Stand)

FHU = FULL HOT UPRIGHT: when reading the dipstick with the bike upright and level you will take the reading from the dimples labeled FHU (Full Hot Upright)

Available in polished or fade-resistant black

Made in the U.S.A.

VENTED DIPSTICKS

NOTE: These dipsticks do get hot; use a glove when checking oil level.

NOTE: Feuling highly recommends staying off the rev limiter and running conventional oil in the M-Eight engines to help maintain ring seal and minimize blow by.

NOTE: It is important to get the correct hot oil level in your bike. Feuling recommends running the oil level 90%-99% full when hot.

NOTE: The oil pick up port is on the right side of the engine. Letting the bike idle or warm up on the kickstand will naturally fill the engine case and skew the oil level in the tank.
