I have never changed oil on a bike with an oil tank on it, Is it just like a bike without one? Remove the drain plug and it ALL drains out.

Secondly: I usually put half a quart of Lucas Oil in when I change my oil, Does a Harley react in any certain way with to where I shouldnt put it in the oil?


Thanks

Make sure it isn't the crank drain plug you are talking about.


If you remove the crank drain plug, it will not drain the oil tank.

Wouldnt I have to drain the oil out from under the motor as well though?

No, but you need to run the bike for a few minutes before you drain it. This assures that there is only minimal amount of oil in the crank case. You'll drain 85-90% of the oil when you empty the tank. The rest stays. It's no big deal as long as you are changing a regular intervals and there is no unusual contamination.

Also, pop the filler cap/dip stick loose before you drain it. It'll drain much easier.

You really need to get the service manual if you plan to do your own service. There is a lot of information in there you're going to need.

use TFE paste on the drain plug threads, with a new "O" ring ACE hardware has "O" rings & don't overtighten the drain plug.twin cams use #41 "O" ring.
