Feuling Parts Vented Dipstick — Black

Overview

This vented dipstick lets crankcase pressure breathe out of the oil tank through a PCV-style system that reduces blowby buildup and improves overall crankcase ventilation. The assembly uses an oil separator, perforated disc, replaceable filter element and an umbrella flapper valve to control venting and keep oil where it belongs.

Key features and benefits

• Vent/breathe excessive crankcase pressure from the oil tank to reduce blowby and oil loss.
• Screws into the factory oil fill spout as a direct replacement for the stock dipstick.
• Fueling tests show reduced oil sump loss, smoother revving, and improved mpg.
• Includes two venting-style installation options: 1/8 NPT breather vent with internal porous filter, or quick-disconnect coupler with rubber hose and filter element.
• Two oil-level reading methods: Full Hot Stand (FHS) on the jiffy stand or Full Hot Upright (FHU) with the bike level.

Installation notes: the oil pickup is on the right side of the engine; warming the bike on the kickstand can skew tank reading. Feuling recommends running the hot oil level at 90%–99% full. This dipstick will get hot in operation—use a glove when checking levels. Made in the USA.
