levels are 20w 50 oil, synthetic is best,change filter,add 3 quarts 20w50 in oil tank,, then drain primary which also feeds transmission, replace drain plug and add 1 quart of same 20 w 50 in primary, it used to be a separate special primary oil. but now it is changed to simplify the procedure, so for complete oil change you need to buy 4 qts 20w50 3 for oil tank 1 for primary and an oil filter,. hope this helps

Use Harley trans Fluid or Harley Formula +
You should only use Harley transmission fluid from the dealership. It's engineered by Harley for their transmissions.

You could use a dip-stick or check the gages, there are gages for everything on those modern bikes.
Harley Sport-Trans Fluid if you can find it. I use it in mine religiously. Works great!
You can use any SAE certified transmission fluid in your 1987 Harley-Davidson Sportster motorcycle. The manufacturer recommends that you never overfill the transmission fluid.
24 oz. of Harley Davidson Formula+
In as much as Harley has discontinued Sport Trans Fluid and it's now an obsolete part number I think the only HD product out there is Formula+ for your use.
