Ventilated dipstick. Black

Hard anodised black finish.
The Feuling billet aluminium dipsticks vent/depressurise excessive crankcase pressure through the oil tank via a PCV-type breather system, consisting of an oil separator, a perforated disc, a replaceable filter element and an umbrella-type butterfly valve. The Feuling vented dipsticks screw into the factory oil filler neck as a direct replacement part. These venting dipsticks eliminate unwanted build-up of burnt gas pressure in the oil tank.
Blow-by gases are the pressure that leaks past the rings and cylinders, enters the crankcase and is then forced into the oil tank. FEULING dipsticks help eliminate this unwanted pressure through a Crankcase Ventilation System (CVS). Test results show a decrease in crankcase oil levels, an engine that spins more freely and smoothly, an increase in fuel performance (MPG) and a reduction in blow-by gases.
Note: All internal combustion engines have a certain amount of blow-by gases. Larger displacement engines, as well as engines with worn or loose ring clearances, will have increased blow-by gases. Engines subjected to extreme limits will also produce excessive blow-by gas build-up that "robs power".
We include 2 vent styles (Options) to choose from when installing the dipstick:
OPTION 1.) 1/8 NPT threaded breather fitting with internal porous filter element. This option offers a clean look, but may produce oil mist/debris outside the element on engines with excessive blow-by/burnt gases.
OPTION 2.) Quick-disconnect fitting with rubber hose and filter element. This option routes excess oil mist/residue through the line and into the filter element. However, this option requires disconnecting the fitting to check the oil level. This is Feuling's preferred option as it vents better than option 1.
For option 2, we recommend routing the line up the frame rail, below the seat/fuel tank area, and then down along the right-hand frame rail. The filter element can be neatly placed between the engine/transmission junction area on the inside of the lower right rail.
Note: This dipstick heats up; wear a glove when checking the oil level.
Oil level check:
There are two ways to read the oil level with this dipstick: with the bike on the side stand (FHS) or with the bike upright and level (FHU).
FHS = FULL HOT STAND (Full, hot, on the stand). If you read the dipstick with the motorbike on its side stand, take the reading from the notches labelled FHS (Full Hot Stand).
FHU = FULL HOT UPRIGHT. When reading the dipstick with the bike upright and level, take the reading from the notches labelled FHU (Full Hot Upright).
OIL LEVEL - DO NOT OVERFILL THE OIL TANK It is important to achieve the correct hot oil level on your motorbike. Feuling recommends keeping the oil level between 90% and 99% full when hot.
Note: Leaving the bike idling or warming it up on the side stand can naturally fill the engine case and alter the oil level in the tank.
We recommend the following steps to achieve the correct oil level:
1. Check the oil level when cold.
2. Ride the motorcycle until it reaches operating temperature.
3. Switch off the motorbike whilst it is still in an upright position (this ensures an accurate reading).
4. Once the motorcycle is on the side stand, check the oil level.
5. Add or remove oil as necessary.
Note: Feuling's internal testing shows that venting the air filter to the atmosphere can be problematic, resulting in oil/mist carry-over out of the breathers. When air filter venting is accompanied by the use of oil tank venting, such as the Feuling vented dipstick or a vented transmission top cover, oil carry-over/mist can increase.
