What should my Harley oil pressure be?
Oil never gets above 225, usually runs about 180-210F. Above 2,500 RPM’s, pressure increases to about 30-32 psi.
What is Harley oil Sumping?
Oil sumping or wet sumping is a condition where oil, instead of returning to the oil tank, builds up in the crankcase and cam gearcase, causing excessive friction and power loss. Sumping is when the suction side of the oil pump does not remove enough oil from the crankcase.
What happens if I overfill my Harley oil?
When you add too much oil, the pressure on the crankcase increases. When you have overfilled the engine oil, the extra oil will go towards the crankshaft, and as the crankshaft keeps rotating at high speed, this oil gets mixed with air and becomes foamy causing a smoky exhaust.
Do Harleys really leak oil?
Harleys do not leak engine oil. Early Harleys used an automatic lubrication system that drew oil from the oil pump to lubricate the primary chain.
How do I adjust my oil pressure?
Turn clockwise to increase pressure, counter-clockwise to lower. Replace rubber plug when done. An easy way to adjust the sender is to turn the motor over with the starter-ignition off. The oil or fuel pressure will rise slowly.

Where does the oil come from in a Harley Davidson?
Top breathing engines breath, or vent, through the top breather bolts which are threaded into the heads of a Harley Davidson motor. The air inside a motor is saturated with oil. It exits through the breather bolts and into the airbox where the air is filtered and the oil is captured in the air filter.
Why is oil dripping from my Harley air cleaner?
Same problem on a 2012 ultra.tried running low oil didn’t work just junk harley internal parts. Don’t blow out with compressed air! You will ruin the element. Shake the filter and them let it air dry. Phooey… As long as it’s not high pressure, keep it to 10-15 psi, it’s fine.
How does a Harley Davidson Top breathing engine work?

Why does the oil go backwards on a Harley Davidson?
When the housing loads up with too much oil, droplets form which will fall downward when the bike is still or spray backwards if it’s in motion. If you see a Harley piddling oil from the air cleaner — even a modern one — that’s what they’re engineered to do.
Why does oil leak out of the crankcases on a Harley Davidson?
If the bike sits without running for any appreciable time period, the crankcases fill with oil that slips by. Upon startup, the scavenging pump gets overwhelmed. Thus, the oil blows out the crankcase breather or air cleaner in copious amounts.
