We just got our break-in miles done on our brand new Milwaukee-Eight-powered Road Glide, so we're going to throw some fresh Motul in it and get it back on the road. But first let's take a look at the tools we're going to need to do this job. You're going to need a 3/8" ratchet with a six-inch extension, a 5/8" socket, oil filter wrench, and a torque wrench.

So we've got to get the oil out of this bike. The first thing we're going to do is pull the dipstick out. Loosen it up to make sure we can draw some air through and it doesn't get a vacuum and leave oil in the system. So going underneath, you're going to want to make sure you picked the right plug here (0:37), because otherwise you'll drain the transmission. It's the one that's facing forward on the left-hand side of the transmission oil pan.

To pull your drain plug out, there's a magnet. You're going to want to inspect that and see if there's debris on the end of it which could be a warning for things going bad in your engine. Also, inspect this O-ring here (1:00) It's not a bad idea to replace that. Order one when you order your oil and filter because you put this back in and if that O-ring leaks, you'll have to take all that fresh oil back out just to replace this little ring.

So, our oil has slowed to a drip. You've got a rag there to catch it, but I want to go ahead and put the plug back in now so I don't forget to do it and dump all the new oil back out the bottom of the bike. We're going to go ahead and snug it back up with a ratchet. Then we're going to hit it with our torque wrench. The manual calls from anywhere from 14 to 21 pounds. We've got ours set at a nice 16 foot-pounds and will go ahead and get the plug back in there.

Now that we've got our drain plug back in, we're going to hop over to the other side, get our filter off, get our new filter back on, and get some oil in this thing. First we have to take our old oil filter off. You can get in there and hack around with a screwdriver and chain locks but I highly recommend an oil filter wrench. It'll save you a lot of hassle. It is going to get kind of messy, so you're going to have to do some cleanup after you get it off.

Pull the old filter and clean this up in here a little bit (2:33). We're going to spray it down and then we're going to take our new filter and lube the top before we put it on. We're also going to want to pre-load it with some oil. Fill it up about halfway before putting it back on.

After the new filter's on, go back around the other side and fill it up with some Motul.

So we're all set to fill her up. The new Milwaukee-Eight takes four and a half quarts. We're going to start with the one that we pre-loaded our oil filter with and go from there. After getting four quarts in, add the last half quart. Then we're going to fire the bike up because we're going to want to check the oil level when it's warm.

Once the bike's good and warm, we can check our oil level. First I need to lower it down off of our centerstand. Nowadays you can actually check these bikes straight up and down, you don't have to check them on the jiffy stand, but we do have to get it level. Not only do we have to check this when it's warm, we have to make sure the cap is screwed all the way in, so when you're checking your level, make sure you screw that cap all the way in there.

Like I was saying, used to be you had to check these on the kickstand, AKA the jiffy stand. Now the dipstick has two levels, one for checking it on the kickstand and one for checking it when the vehicle is upright. Since we're upright, we're going off of this fill level here (4:55). We're right in the middle, so we're in good shape.
