You won't find an engine oil one, it has a dry sump and is located on the oil tank.
The gearbox however has one, under the engine between the gear change lever and oil pump.

your oil drain is on the right side pipe side of your bike look under near the rear back part of your frame you will see a plug with a one quarter allen key threaded plug style bolt kinda hidden in bridge plate of frame it is flat in conjuction with line on bike it is in area right behind where your back pipe expands to baffle of pipe where its skinny and then gets bigger its the one closest to you

Why can't I see the replies to your question in this thread. I have the same problem with my Harley. It rolls in gear. I don't need to reply to your question. I just need to read the replies. Aggravating

Question edited for FULL 'year make model'. Question moved to the correct category from 'Fat Motorcycles'. Remove the tanks with fuel pipes. Push a bolt or plug into the open end of the pipes and clamp with a hose clip. Fill the tank and see where the fuel is coming from? The most likely reason is a vibration crack somewhere or a split breather. Other ideas here https://www.google.com/search?q=2013+Harley+Davidson+FLSTF+fuel+tank+leaking ..

Question edited to add Maker. Question moved to year make model category. No description of the noise. Does it should like timing chain rattle? Maybe the tensioners are worn? Check the oil level as well. https://www.google.com/search?q=2004+harley+davidson+flstc+heritage+softail+tensioner+timing+chain ..

Harley-Davidson EVO may be backfiring on the rear cylinder because it has a wasted spark system. If fuel and electrical is all good/correct it is often the case in these symptoms that motor cycle spark plugs that although looking good and firing outside of the engine are breaking down and will not fire under compression pressures on a power stroke but will fire unburned fuel on the unpressurized exhaust stroke when the plug again fires in a wasted spark ignition system and when so firing the result is a backfire, usually quite loud.

I've seen some oil down around the cylinder base, re-torque the bolts until you decide to replace the possibly stretched bolts or base gasket. Be gentle and do it in sequence.

Question edited for clarity, FULL year make model. Question moved from Cars and Trucks to HD model category.. Yes, it is a known issue. https://www.google.com/search?q=2007+Harley-Davidson+FXSTC+rear+LED+turn+signals+and+brake+light+blow+the+fuse ..

not told how old the fuel is and can be bad 1+ year old compression good good fuel carb clean. spark good. filters not clogged. electronics speedo or cable driving, no way cable can fail parked at 0mph, but if electronics to not work with dead or weak battery 10vdc is min 12.6vdc is good key off rested. a good battery is first, the bikes generator may not run the biked proper if battery overloads any gen. so batter good is first on bike.

google it or ask Harley directly you to them.

I'll bet you've got that vacuum operated petcock on your bike too. Not saying this is the problem but I've seen more problems with them than I care to mention. They're only on carburetur equipped bikes. You didn't say which you had but if you've got one, I'd check it out.

You can drain the tank and remove the petcock. Check the condition of the screen filter that is in the tank. On the backside of the petcock, the should be a small vacuum hose connected to the petcock. Take this hose and the fuel hose loose. On the backside of the petcock is square plate held on by four screws. Remove the screws and lift the plate. There is a diaphragm, a small spring, and a needle in there. Take the needle out and use compressed air to blow everything out, Rotate the fuel selector lever and make sure both the on and reserve position is clear in the petcock. Now, hold the diaphragm up to the light and stretch is slightly. Look for holes. If you find a hole, replace the diaghragm. If not, reassemble the petcock.

The vaccum hose that supplies vacuum to the petcock is very small. It comes off a large hose that supplies vacuum to the VOES switch under the top tube of the frame. The vacuum is supplied by a nipple on the backside of the carburetor. Check this hose for cracks or being unplugged.

What I suggest is that you replace the petcock with a high quality manually operated petcock. I like the Pingle petcocks. They're expensive but well worth the money. You'll have to get into the habit of turning your fuel off when you stop the bike like the "old school bikers" do. Just a precaution in the event a piece of trash gets in the needle and seat of your carb.

Now, there are other things that could be causing this. A bad gas cap for one. If the vent in your gas cap is bad, a vacuum will build up in the tank and starve the carb for fuel. you can test it in either of two ways. Loosen the cap (don't take it all the way off) and ride the bike. If the problem goes away, buy a new gas cap. Or, the shop method of testing them when you don't have time to ride the bike. Take the cap off, wipe off as much gasoline as you can, stick the threaded part in your mouth and **** and blow on it. If you can **** air and blow air through the cap, it's fine. Now, go find the Scope mouthwash or everyone will call you "Gasoline Breath" for the rest of the day.

If your bike is fuel injected, you might want to check the electric fuel pump. Other than that, I can't help you with the fuel injection. I know nothing about it as Harley is very secretive about that.

Good Luck

Question edited for clarity, full make and model. Question moved from Cars and Trucks. Check the main fuse, and then you need to find out why it blew. https://www.google.com/search?q=2002+night+train+fuse+box+diagram ..
