2000 RKC Drain Plug Locations

Probably a common mistake.

I took a digital pic after my first oil change so I didn't forget.

This will help other first timers:


Also, here is what I typed out for my own use:

OWNER’S Manual Recommends Oil Change Every 5,000 Miles

**using 4 Quarts 20w-50 Amsoil synthetic ...noted in forums as very smooth for the bike

Actually all you need is the Harley oil filter wrench which fits over the end of the filter and has a cut out for the oil sending unit that is on the other Harley models. Or if all else fails drive a screwdriver into the side of the filter and lever it counterclockwise to loosen.

make sure the bike is at operating temperature so that the warm oil will run out smoothly.


1. place an oil pan under the drain plug area AND on top of some old newspapers. Use a paint roller pan to catch the oil

** LOCATE OIL DRAIN PLUG via JPG picture, it's on the bike's LEFT side and mounts into the drain pan HORIZONTALLY -- the vertically mounted drain plug on the bike's RIGHT side is for Transmission Oil.

2. Loosen the plug using a 5/8" socket or 5.5mm/ 1/4" Allen wrench (counter clockwise).
3. From the high side of the bike with the kick stand down. Remove the plug and allow the warm oil to drain into the pan (this may take awhile--even when warm). Remove oil cap to allow good draining.
4. Check the oil plug end for metal filings (it's magnetized) wipe it clean.
5. When the oil stops dripping carefully slide the pan out form under the bike on the newspaper and reinstall the oil plug AFTER placing some oil on the "O" ring seal.

BE CAREFUL TO NOT OVER TIGHTEN THE PLUG, or risk damaging the o ring seal. 14-21 ft.lb torque

Removing Oil Filter

1. place an oil pan under the filter area AND on top of some old newspapers. Rig up a cardboard trough or manila envelope in a V shape underneath the filter to catch the oil that will drip from it.
2. Place the oil filter wrench over the end of the filter and using the 3/8ths drive extension and ratchet, turn counter clockwise to remove it.
3. Wipe up the oil from the engine and filter areas.
4. Put some oil on your finger and run it around the rubber seal on the new filter to lubricate it.
5. Spin it on until it seats and then go another 1/2 turn to tighten it properly.


** Should take just under 4 quarts
** put the bottles of oil out in the sun so they empty quicker and more completely

1. Remove the oil dip stick in the front of the motor.
2. Pour 2 Quarts of new oil in the motor.
3. Start engine for ~45 secs to allow oil to fully circulate so you can add the rest of the oil.
4. Add another 1 1/4 or 1 1/2 Quarts
5. Wait for about a minute and check the level
6. If it is low add more oil Until the dip stick reads full WHEN THE BIKE IS LEVEL.
7. Take the bike for a 3-4 mile run.
8. When you return let it sit for a few minutes and then check the oil level on the dipstick and add as necessary until the level reads full.
9. WRITE DOWN how much oil you used for YOUR MOTOR (there is as much as 3/4 of a bottle of oil differences in oil amounts from one motor to another) on a piece of paper and place it where you can find it the next time you need to change your oil.
10. Place newspaper under the bike for the next 24 hours to locate any leaks
