First off it's a waste of time since the new oil added is good enough. On a Softail, it's on the cam galley side, so all you get is a small amount of oil.

And on a cruiser it in a very thin area. It's a tapered 1/8 " per foot pipe thread. Harley seals it with a dry set sealant.

That taper if over tightened just a little will crack the block. There is no torque call out, so it simple takes experience dealing with it. What I said is what the service manual says. Crack the block and it's a couple grand repair.
Think I have see three on here. And even more of the 1/2-20 straight thread MS o-ring seal plug hole cracked and stripped.

Don't ask me any more questions..

So, if you have a manual and would like to share the correct specs on engine oil, trans, & primary capacities, please follow below:

PLEASE CONTRIBUTE THE FOLLOWING:
----------------------------------------------------------------------
Year, Model, and engine size of the bike: 2007 FLSTN Heritage softail Delux

Engine oil capacity:__3Quarts-2.8 litres_______

Transmission capacity:__32 Ounce-.95 Liters_______

Primary case capacity:_32 Ounces-.95Liters________

Do not overfill especially primary as it will cause clutch to get wet. Don’t overfill engine as it will bleed out the dipstick hole.

if the bike's level, I don't think I could overfill the primary on mine???
it'll dribble out of the hole the derby cover covers (whatever that hole is called)

Not true....

If your bike is level, and fluid comes out the derby cover hole, you are way overfilled....

Yeah, Dan... but I can't help myself and sometimes feel the need to respond...

PGA, you know most Harleys have a wet clutch, right?... FYI.... the clutch plates are supposed to be wet... not submerged, but wet... they are designed to work that way..

While not overfilling engine oil is a rather obvious statement, it's easy to do on a softail if you don't check it properly. Especially after a period of non-use, you need to check the oil as directed in the Service Manual.. This is due to the dry sump oil system, with an oil tank above the sump...

You need to ride the bike until the engine is up to operating temperature, and the Service Manual even says to let it idle for a minute or two on the jiffy stand. That ensures all the oil is scavenged back into the oil tank from the sump.. This ensures an accurate dip stick reading..

If oil is coming out your dipstick... you usually either have an engine crankcase venting problem, or you checked the oil improperly...

Primary case capacity = 26 ounces

I have that same bike. I bought it new. I put a HD oil cooler on mine. I wonder how much the engine oil capacity was increased.
