How do you check primary oil on sportster - 2004 Harley Davidson XL 1200 C Sportster Custom

SOURCE: o2 hd sportster 1200 what

Your bike came with H-D 20W50 Syn3 engine oil in the primary. You can run other brands as well but check the manufacturers website for compatibility. In your Sportster, the clutch and transmission share the same lubricant. You need to make sure that the oil you use has the frictional characteristics suitable for use with the wet clutch.

Good Luck

Use 1 quart of 75-90 gear oil. I use Mobile 1 full synthetic.

Drain the oil tank by taking the hose loose that plugs onto the frame on the left side of the bike right behind the engine down low. Look underneath the engine and you see a small plug that screws into the primary cover from the bottom. This plug uses a Torx wrench to remove it.

Change the oil filter. This is a messy job as oil pours out of the filter as you unscrew it from the engine. Install the new filter and tighten. Add three quarts of oil to the oil tank of the engine and one quart of primary/transmission oil to the primary. The primary and transmission are lubricated by the same oil. I think the later model bikes came with Syn3 oil in both places.

Your looking at 2.8qts for the engine add another 1/2 quart or so for the filter. Always put a little oil in and then add till full. Use the amounts identified as a guide to how much oil to have on hand. You primary may use 22 - 28 ounces, and your tranny a little less than a quart. so have at least 5 quarts available for a complete fluid change (and filter) and you should be good to go! Hope this helps.
