So I noticed a week or two ago that I have a drop of oil forming on the bottom left side of the engine where the left side engine cover attaches to the case. I cleaned the bottom and inside the sprocket cover to see if I could trace where it is coming from. After 24 miles today I noticed where it is coming from. If I remove the sprocket cover I can see the the side of the case is wet with oil all the way up until where the wires enter the case cover. I am guessing these are the alternator/generator wires but could oil be leaking from there? It seems that it is. Can anyone provide me a blow up of the parts or some sort of guess as to where the oil is leaking from?
I am still under warranty and will probably stop by a dealership next week to have it looked at, but would like some ideas before I go in.
Thanks in advance.

Re: DL650 Oil Leak...what can it be?
This is on the chain side of the bike, isn't it?
i hope you always made damned sure your chain wasnt too tight when you adjusted it...
i doubt this would be a problem on the wee, but on my gs1150, i had an offset sprocket so the chain would clear the larger gsxr rear tire i had i can't remember which size the tire was(185?), but my front sprocket was offset 3/8.
well, the chain was too tight on that bike and the output shaft toasted the bearing, and that made some neat damage to my engine cases, the symptom i got was lots of smoke coming from there, oh that and the oil leak that looked a lot liek what you describe.
however, greywolf knows the strom way better than me and his suggestion of the clutch pushrod seal makes sense. on the gs, the clutch is on the opposite side from the sprocket, so it's an impossibility.
so check the clutch seal, also check your output bearing seal.
dont fret my horror story, as i said, unlikely on a strom, and never happened on a gs1150 either, only happened because: A- too tight a chain B- offset sprocket.

You need a gasket. Don't we be the bearer of bad news, but I think you have to drop the engine, one that bike to get to that gasket about 750 dollars you could try to stop leak. Just make sure it's good quality
The o-ring on the filter housing could be the problem, or maybe it was not tightened properly. You will need to clean all the residual oil off, position you bike in the upright position and determine the leak source. Hopefully it's not a case cover. Good luck, i hope this helps.
Well, I don't know about a Big Dog but I do know how the dipstick on a Harley is set up. You have two marks on the stick. The top mark is "FULL HOT" and the lower mark is "FULL COLD". Since the S&S engine is just like a Harley engine in that it is a dry sump type engine. When you check the oil when the engine is cold, as long as the oil is touching the dipstick, you should be OK to ride. Once the engine comes up to temp, then check the oil and bring it close to the top mark. Do not overfill. Never add oil to a cold engine unless you cannot see oil on the stick.
Now, for the leak on the left side of your bike. Now you said that your Big Dog is a custom chopper and your replaced the main seal. You did not tell me whether your primary drive is a standard chain drive primary or an open belt drive as so many "custom choppers" run. If you replaced the main seal, did you lubricate the inside lip of the seal before you installed it. If not, when the engine starts up, the friction will burn up the lip of the seal before the oil gets to it. It only takes a half second to burn the lip of the seal. Always put oil or light grease on the seal lips when you install a seal.
If your primary drive is a standard chain type, the leak could be a bad engine to primary O-ring that goes between the engine and the inner primary cover.
Another place that the oil could be coming from is the nosecone. If the oil is leaking out of the bottom of the nosecone, it can leak down to the centerline of the cases. When you put your bike on the kickstand, the oil will then run across to the left side and drip off. The best way to find the leak is to clean everything off as clean as you can get it. Then go for a short ride and come back and look for the leak.
The oil tank for your Wide Glide is on the bottom of the transmission. There should be two drains, one for the engine oil and one for the transmission. The oil drain is usually the lowest drain when the bike is on the side stand, the one closest to the left front of the oil pan. You can tell the instant you see the first drop whether it's engine oil or transmission oil. Engine oil will be black and the transmission lube will be almost clear. If you drain the transmission instead, it takes 20-24 ounces of the same H-D Syn3 20W50 engine oil.
Hi, if the engine is leaking from underneath, its possibly oil pan gasket/ oil drain plug seal/ oil filter o ring needs replacing. The other leak you describe could be the bottom cylinder head gasket, if so the only solution is to replace it. I have this problem on mine, oil weeping from same area. cost would be about
leak or anything that I know of anybody else have this issue?When checking the oil get the engine warm (not hot), let is rest for about 10 minutes and then check. This will allow the oil in the engine to flow back into the resevoir.,,,
