Title: 2016 throwing oil out the Air Cleaner
Post by: tmatahead on October 29, 2021, 09:52:26 PM

I’m running it half a quart low, after 2500 trip, oil is saturating the air filter. Oil is covering the rear cylinder exhaust pipe, a puddle between cylinders. I hear a ventilated dip stick is the way to go.

Has anybody done a D.I.Y. Ventilated dip stick?  I just can’t see spending $300 for a vent & tubing.

That sounds like high internal pressure build up.
Might be a good idea to remove the spark plugs and use a scope to check the cylinder walls for scoring.

Usually excessive blowby causes carry over, fix the root cause not add a bandaid which won't work.

Now your running it where the oil level should be. Harley's will do that when overfilled. I run a A1cycles vent cap kit that cost me around 50 bucks. Id route a longer hose to run the vent filter like the tman video on you tube.
