New from Oceanside, California based Feuling Parts, this new billet dipstick vents/breathes excessive crankcase pressure from the oil tank through a breather system consisting of a replaceable filter element and umbrella flapper valve.
Feuling vented dipsticks screw into the factory oil fill spout as a stock replacement part and remove the unwanted build-up of blow-by - found in engines with excessive leak-down through the rings/cylinders - a common issue with large displacement big bore engines.
Feuling test results show a decrease in engine oil sump levels, a more freely/smoother revving engine, increased MPG and decreased blow-by. The company includes two venting options to choose from when installing the dipstick.

| Option 1 |
Option one 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."

| Option 2 |
Option two is a 1/8 NPT breather vent fitting with an 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 leak-down/blow-by.
"It is important to get the correct hot oil level in your bike," says Feuling Parts CEO Luke Leatherman. "We recommend running the oil level 90%-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.
"To achieve the proper oil level, we recommend taking these five easy steps. First, check cold oil level; then ride the bike until the desired operating temperature is reached; then shut the bike off while still in the upright position (this ensures an accurate reading). Once the bike is on the kickstand, re-check the oil level and add or remove oil as needed and remember, our dipstick does get hot, so use a glove to check the oil level."
