FEULING PARTS Vented Dipstick — Polished – 17-25 Touring, 17-25 Trike, 18-24 CVO

Billet dipstick vents excessive crankcase pressure from the oil tank through a PCV-style breather, using an oil separator, perforated disc, replaceable filter element and umbrella flapper valve.

It screws into the factory oil fill spout as a direct replacement and removes unwanted build-up of blow-by pressure in the oil tank. 🛢️

• Two venting options: 1/8 NPT breather with internal porous filter element, or quick-disconnect coupler with rubber hose and filter.
• Two ways to read hot oil: full hot stand (FHS) on the jiffy stand or full hot upright (FHU) with the bike level.
• Testing shows reduced engine oil sump loss, smoother revving and improved mpg from decreased blow-by.

Important: keep the hot oil level between 90% and 99% full. The oil pickup is on the right side; warming the bike on the kickstand can skew the reading.

This dipstick does get hot; use a glove when checking oil level. It also helps to avoid the rev limiter and to run conventional oil in M8 engines to preserve ring seal and minimize blow-by.
