Vented Dipstick
This billet dipstick vents excess crankcase pressure from the oil tank through a PCV-style breather. The system includes an oil separator, a perforated disc, a replaceable filter element and an umbrella flapper valve to manage blowby and keep oil contamination low. 🛢️
- Screws into the factory oil fill spout as a direct replacement.
- Design vents blowby pressure forced past piston rings into the crankcase and then into the oil tank.
- Fueling test results show reduced sump oil loss, smoother revving, and improved MPG.
- Removes unwanted buildup of blowby pressure in the oil tank.
- Two ways to read oil level: with the bike on the jiffy stand (full hot stand, FHS) or upright and level (full hot upright, FHU).
- Includes two venting options: 1/8 NPT breather fitting with internal porous filter element, or quick-disconnect coupler with rubber hose and filter.
- It is recommended to run the hot oil level 90%–99% full.
- The oil pick-up port is on the right side of the engine; warming the bike on the kickstand can skew tank level.
- Made in the USA.
- This dipstick does get hot; use a glove when checking oil level. 🧤
