You could get away with it for awhile, but I would only use oil formulated for the primary chain case, and for that part of the machine, I stick with Harley brand, dont forget , u got clutch plates in there u dont want slipping. For the tranny you wanna use a good grade gear oil (75W-90, 75W-110,75W-140, SAE 190 & SAE 250) .... it'll better handle the torque requirements. I use Redline Gear Oil and shifting has improved noticeably

Yes, The first thing you do is disconnect the battery ,,,Harley says to pr3vent accidental starts, but if you dont, your going to short something out..... You are going to have to remove the outer primary to get to the jackshaft. Disassemble and pull the jackshaft then you can unbolt and remove the starter ,,,,,

SOURCE: engine oil plug
Another way to locate it, is with the bike on the kickstand, look underneath of it from the right (brake) side. The oil drain plug is on the front of the square looking pan under, and to the rear of the engine. The oil drain is the plug on the front of that pan, on the left (shifter) side of the bike. The trans drain is on that same square looking pan, but towards the right side, and faces down. It screws in and out vertically, whereas the oil drain is horizontal

Turn the Bike on and the Radio off and then follow the buttons on the screen. Most people think you have to do it while it is running and this does not work

Your '98 Evo motor is what they call a "head breater" engine. This means that the crankcase ventilation is at the upper end of the heads rather than way down at the lower end of the engine like it used to be. They the first year for the "head breaters" was 1994.
Now, At the top of the heads where the rocker boxes are, there are three pieces. The lower rocker plate with the rocker arms in it, the middle piece and the upper cover. If you take the four bolts out, you'll see an umbrella valve in the middle piece of the rocker boxes. This valve is a replacable rubber piece. Over time and many times of heating up and cooling down, they can get brittle and allow a lot of blowby resulting in oil in your air filter element.
Now there is another part in the cam chest that has a lot of effect on the operation of the crankcase breather system on your bike. This part is called the "breather gear" and is located down in the cam chest to the rear of the camshaft. In you bike, the part is made of plastic if it's the original part. I have seen the teeth break off of the drive gear and the breather gear stop turning. This will screw up the "breathing cycle" on your engine and cause it to "blow oil". Usually, the oil pump locks up when this happens due to the plastic teeth getting in the oil pump but not always. If this eventually turns out to be your problem, have the mechanic or yourself install one of the new S&S reed valve type breather gear replacements. They don't turn at all and work absolutely great. The part is about a hundred dollars but it's well worth it. Solves the old broken breather gear problem that has plauged the Evo engine it's entire life.
There are no "screens" in the Evo engine other than the "tappet oil screen". Just in front of the oil pump is a screw plug that is in the engine cases itself. If you remove this plug, there is a small spring and cone shaped screen that filters the oil prior to it going to your tappets. This should be cleaned every other oil change but it has nothing to do with the oil in your breather.
Now some riders will tell you that if you allow your Harley to sit for any length of time that it will "oil sump" with you. By this, they mean that oil will seep past the check ball in your oil pump and pool up in your crankcase. When you start the engine up, oil will be blown into your oil filter. Not true on your Ultra. The bikes that will oil sump are the Sportsters, Softails, Shovelheads, or any bike that the oil tank is higher than the oil pump on the frame. On your Ultra, the oil tank is on the bottom of the transmission. Your bike will not "oil sump" unless you have a sheared key in your oil pump or the oil has somehow learned how climb. You oil tank is below your pump in other words and oil does not flow uphill.
