Feuling M-8 Vented Billet
Dipstick Options
Here is more on the Oceanside, California
based Feuling Parts' new M-8 vented billet
dipsticks that we featured in AMD a few
months ago.
The design vents/breathes excessive
crankcase pressure from the oil tank
through a PVC style breather system
consisting of a replaceable filter element
and umbrella flapper valve. They screw into
the factory oil fill spout as a stock
replacement part and remove the unwanted
build-up of blow-by found in all internal
combustion engines with excessive leak-
down through the rings/cylinders - a
common issue, especially with large
displacement and big bore engines.
Larger cubic inch, worn or loose ring
clearance and 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. 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.
Option 1
Feuling offers two options. First, a 1/8 NPT
breather vent fitting with internal porous
filter element. This option gives a clean
look, however, it may produce an oil
misting/residue out of the element on
engines with excessive leak-down/blow-by.
The second option is a 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 require disconnecting the quick
disconnect fitting in order to check the oil.
"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."
Feuling highly recommends staying off the
rev limiter and running conventional oil in
the M-8 engines to help maintain ring seal
and minimize blow-by.
There are two ways to read the oil level
with this dipstick, with the bike on the jiffy
stand (FHS - Full Hot Stand) or the bike
upright and level (FHU - Full Hot Upright). If
reading the dipstick with the bike on the
jiffy stand, take the reading from the
dimples labeled FHS (Full Hot Stand). When
reading the dipstick with the bike upright
and level, take the reading from the
dimples labeled FHU.
It is important to get the correct hot oil
level in the bike and Feuling recommends
running the oil level 95%-99% full when
hot. 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.
Feuling says that the proper procedure to
achieve proper oil level is to check the cold
oil level; then ride the bike until the
operating temperature is reached; shut the
bike off while still in the upright position
(this ensures an accurate reading). Once the
bike is on the kickstand, check the oil level
and add or remove
oil as needed.
