Ventilated dipstick. Polished

Feuling's machined aluminium breather dipsticks vent/depressurise excess crankcase pressure from 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 flutter valve. Feuling breather dipsticks screw into the factory oil filler neck as a stock replacement part. These dipsticks eliminate unwanted combustion gas (blow-by) pressure build-up in the oil tank.
Blow-by is pressure that leaks past the rings and cylinders, is forced into the crankcase and then forced into the oil tank. FEULING rods help eliminate this unwanted pressure through a Crankcase Ventilation System (CVS). Test results show a decrease in crankcase oil levels, an engine that turns over more freely/smoothly, an increase in fuel performance (MPG) and a reduction in blow-by.
NOTE: All internal combustion engines have a certain amount of blow-by. Larger displacement engines, as well as engines with worn or loose ring clearances, will have more blow-by. Engines pushed to the limits will also produce excessive blow-by build-up that "robs power".
We include 2 venting 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 misting/residue outside the element on engines with excessive compression loss/blow-by.
OPTION 2.) Quick-connect fitting with rubber hose and filter element. This option routes excessive 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 along the chassis rail, below the seat/pocket area, and then down along the right-hand chassis rail; the filter element can be neatly placed between the engine/transmission joint area on the inside of the lower right rail.
Note: This rod heats up; use 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 level on the side stand). If you read the dipstick with the bike on the side stand, take the reading from the notches labelled FHS (Full Hot Stand).
FHU = FULL HOT UPRIGHT (Maximum level, hot, upright). When reading the dipstick with the motorbike upright and level, take the reading from the notches labelled FHU (Full Hot Upright).
OIL LEVEL - DO NOT EXCEED THE MAXIMUM LEVEL IN THE OIL TANK It is important to obtain the correct hot oil level on your bike. Feuling recommends keeping the oil level between 90% and 99% of capacity when hot.
Note: Leaving the motorbike idling or warming 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 while 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 in-house testing shows that venting the air filter to the atmosphere can be problematic, resulting in oil carry-over/mist escaping from 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/misting can increase.
