How do you vent a crankcase on a Harley Davidson?
I found that you can use copper tubing bent into an “L” shape that inserts into the bottom breathers vent line inside of the air box (evo’s) that will vent right over the inlet of the carb with the end of the tube cut at a 45* shape to expose a bigger profile to the inlet of the carb.
Where is the oil tank vent on a V-twin?
I run my case vent, trans vent and oil tank vent together into one small breather element that loops over between the motor and trans just behind my belt drive or what would be your inner primary. You do want to run a breather filter on it though to prevent any dirt or water in it and it would be impossible for it to go up the hose
Is it possible to run a breather filter on a V-twin?
You do want to run a breather filter on it though to prevent any dirt or water in it and it would be impossible for it to go up the hose The water in the collection can is not water from the oil in the engine, it is water that has condensed into the oil while it was in the can.
Where is the vent on a Harley Davidson scooter?
I have mine nicely routed up to the S&S backing plate in a braided line that is clipped to the rear jug. He currently has a short piece of tubing with a K&N filter attached to it….dangling under the bike. He’s looking at the Hayden Crankcase Pressure Reilief Valve and the Spyke “Stealth” Krankvent. The underside of his scooter is a little oily.

Where is the vent line on a Feuling V-twin?
When accelerating or going up a fairly steep hill the oil in the tank sloshes to the back of the tank and stays there while you’re accelerating, it will flood the vent line going back to the crankcase. You’ll notice on the newer models, they have a vent line that runs from the cam chest back to the dipstick spout.

Can a crankcase be mounted above the oil tank?
I seen aftermarket crankcase ventilation catch can breathers. What’s your thought on mounting the catch can above the oil tank and draining it to the oil tank. Click to expand… You can’t go higher then the venting point, or at least: shouldn’t. Crankcase fumes also carry heated air, which in cold metal, creates condensation.
