Default 75 Ironhead chain oiler

Does anybody have a good picture of the chain oiler? My pictures are all messed up and I can't see what I'm looking for. I just went for my first ride on the bike and 3rd gear was slipping. I pulled into the driveway and oil is running all over. It's coming from the chain side and I figure maybe the chain oiler is not set right or missing parts or broke.

Thanks
Jeremy

It's hard to get a picture of the oiler when the oil tank is on and the bike is together. The oiler is under the starter solenoid. This picture is fuzzy, but its the only one I have. I'm missing the metering screw on mine so it might look a little different than yours. Yours might still have a screw sticking out the middle of it.

Ok, that looks foreign to me. Mine must have been removed before I got the bike. I do have a new oring chain, maybe I just need to use a spray. I'll keep looking for the oil leak.

Thanks
Jeremy

Make sure you have not overfilled the primary/transmission. It takes 26oz of oil.

Then look for the oil to be coming out from behind the drive sprocket. Behind the sprocket is an oil seal around the mainshaft coming out of thre transmission. The seals go bad and usually leak some. It is unusual for a great amount of oil to leak however.

That leads me to the next thing to look at. Actually this is the first thing you should check:

Sometimes the oil feed line to the oil pump gets whacked by the chain. If you are running an O ring chain perhaps this is what happened as they are a wider chain.

Clean off all the oil and then go over the oil line carefully. It has to sit in tight against the frame, being held there by a metal clip.
A lot of oil makes me thing the line has a crack or slit in it. Bad news if the oil tank runs dry, so check this out........ pg

1.5 pints = 16 + 8 = 24 oz. 26 must be that 1970s new math, or something.

After the bike cooled I check the oil levels at the primary filler/check plug and it was just below the plug so I figured it to be fine. I also checked the oil tank and it was about where I started. I started it up again and no leaks besides the drips from the stripped drain plugs. I went for a ride and came back and there was some dripping but its hard to pin point because the whole back half under the motor is wet with oil. I wonder if the tranny was overfilled on the first ride and pushed out the excess when it go hot. I read about the 1.5 pints for the tranny, but it took close to 6 quarts to fill the primary cover to the fill plug which is up about 3/4 of the way on the cover. Am I doing something wrong here? Thats a huge difference.

Ok that must have been painful to read, I found the real oil level plug towords the bottom of the cover. I know where all the oil must have been coming from! Hopefully this didn't damage anything.
