As long as you can see oil in the filler hole around about 3/4 full, or no fuller than about an inch or so from the top it should be ok.

Be sure that the oil level is not higher than the return or breather lines on the tank.

ok thanks. but how about when the motor is drained of oil and tank emptied for oil change? should i just add oil to tank or should i take small screw cap off of primary cover and add some oil into engine also.

i never worked on motors with a seperate oil tank. im trying to understand how the tank lets just enough oil in and out of motor without over filling or underfilling it.

there is a Spring Loaded Stainless Ball Check Valve within the Oil Pump, see that Hex Fitting at the front of your Oil Pump? the spring and ball check are within... Oil that made it's pass thru the motor gets returned back to the Oil tank...
Service Manual and Parts Manual would be cool to purchase

For an engine oil change, just top off the oil tank with the proper amount of oil.
Run the engine for awhile and check the level--it shouldn't change much.

If the bike has been sitting for a long while without any oil in it, I'd squirt some oil into the cylinders before the first start-up. Also, I'd kick the bike over a good ten times or more ( without starting it), so as to circulate oil throughout the system before starting it. If it's an electric start bike, disconnect the spark plug wires and crank the starter for a short while--once again, to circulate oil before starting up.

I believe that adding oil to the primary case is primarily for transmission lubrication--for older Sportsters anyway.

The engine oil is in the tank whenever the engine is not running. The primary oil is separate.

The engine takes 3 quarts with a stock oil tank, for most years. The primary takes 1,1/2 pints = 24 fl oz. Older IronHeads use the same type of oil in both; newer IronHeads use HD Formula+ in the primary. Yours is a newer model in this regard.

You need both of these manuals. Order from local indie shop, HD dealer, J&P Cycles, various eBay and internet sellers. Just put the part numbers into the Google and eBay searches.
