Blow by is pressure that is forced past the rings and cylinders, pushed into the crankcase and then forced into the oil tank. FEULING® dipsticks help remove this unwanted pressure through a (CVS) Crankcase Ventilation System. Test results show a decrease in engine oil sump levels, more freely/smoother revving engine, increased MPG and decreased blow-by.
NOTE: All internal combustion engines have a certain amount of blow by. Larger cubic inch engines as well as engines with worn and or loose ring clearances will have increased blow by. Engines pushed to their limits will also produce excessive build up of power robbing blow by.
We include 2 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. This is Feulings preferred option as it breaths more than option 1.
For option 2, we recommend 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.
Available in polished or fade resistant black finish
*This dipstick does get hot, use a glove when checking oil level
TECH TIP: Feuling highly recommends staying off the rev limiter and running conventional oil in the M8 engines to help maintain ring seal and minimize blow by.
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).
