Haha. Thanks Justin. No. And that little f-n plug better not ever leak again! I asked in a different post if anyone knew what the dang thing was for. I got nothing, crickets, nada. My only guess is that it acts as an oil pressure relief plug - like somebody overfilled with oil and it prevents kaboom of your motor. I’d really be interested in other ideas. Nobody seems to know what the darn thing is for except perhaps ringing up repair bills at the Stealership with a newbie mechanic that is green behind the ears. So they can fix it again and again and again….

Underneath that plug is a nut for the left front cylinder stud. The plug fills in the hole that give you access to the nut on top of the stud.

It is leaking oil on left, right, and front of the head from the headcover down. I have not seen a picture that is similar to mine. I surmise I have more than one issue. Does anyone care to comment? Best regards,

Once they get bad, oil ends up everywhere after a long ride. The plug on my bike was bad when I bought it. The seller had washed the bike and I didn't know it was leaking. There was oil everywhere after a couple of hours of riding. It was blowing down both sides covers and battery box.

You can clean the oil up and scrub off as much oil as you can.

Then remove the vent tube and attach it to a compressed air line with 2-3 psi of pressure. (Don't use more than a few psi or you could blow out good seals and gaskets). I started with my air compressor empty and only let it pump long enough to have 2 psi in the tank).

Then use a spray bottle filled with soapy water to see where the leaks are. Spray the top of the engine and look for soapy bubbles.

Thanks Dave! Glad to know it has a purpose!

Ohiomoto & Dave, thanks for your insight. I went in a replaced the head plug with verslagen1's upgrade this morning. It was leaking oil on the cam plug side as well as on the left side real bad. I'm not sure if they didn't use a lot of gasket maker or if that stuff deteriorates over the years. I couldn't tell it was present on much of the surface.

Best regards,

The head plug is fixed and two other oil leaks as well. However, I have a small area with some oil on it and I can't figure out how it got there. The location is on the very front & bottom of cylinder. Actually, on the 2nd fin up from the bottom all the way across it. It looks like it is on the cylinder wall, not near a gasket or an oil passage. Any thoughts, thanks.

Best regards,

I hit it with some carb cleaner, scrubbed it, and some more carb cleaner. I'm going to go 25 miles, go down a d dirt road, then return home. We'll see how it goes. Thanks for your insight.
