3090 Vented Dipstick Harley Davidson FLD 1690 2012 2013

Features: Billet dipsticks vent/breathe excessive crank case pressure from the oil tank through a PCV style breather, consisting of an oil separator system, perforated disc, replaceable filter element and umbrella flapper valve. Screws into the factory oil fill spout as a stock replacement part. Blowby is pressure that is forced past the rings and cylinders, pushed into the crankcase and then forced into the oil tank. Fueling test results show a decrease in engine oil sump levels, more freely/smoothe revving engine and increased MPG and decreased blowby. Removes unwanted build-up of blow by pressure in the oil tank. 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. Includes 2 different venting style options for installing the dipstick: option 1 - 1/8 NPT breather vent fitting with internal porous filter element, option 2 - quick disconnect coupler fitting with rubber hose and filter element. It is important to get the correct hot oil level in your bike. Feuling recommends 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. Made in the USA. This dipstick does get hot, use a glove when checking oil level..
