Default oil breather tube leak??

I heard that if you put the correct amount of oil in the bike you will sometimes get a little oil breather tube leak so since then I have made sure I'm 1/4 to 1/2 quart low. But I still have this oil leak that drips down on to the clutch case cover. Looks like its accumulating above the cheese wedge and ignition coil area.

Other than taking the gas tank off how hard is it to fix this problem. I am assuming if the oil level is correct then what I need to do is remove the oil breather tube and clean it out. But can't really see up under the tank to see what all is involved. Or even if that's what needs to be done.

Looked in the manual but can't find any pictures or information on cleaning or replacing it. I guess its actually called the crankcase breather hose.

Have you given it the sniff test? Does it smell like oil or does it have a gas smell?

Removing the tank is no big deal at all. Just remember two things; run the tank down to 1/4 tank first so it's not so heavy and cover the big gaping hole under the seat with a towel or something so the rubber grommets on the back of the tank don't drop in there. If they do; forget about finding them. Just order some more. I don't know where they go in that black hole but it seems like it's on the other side of the Universe.

Oh; I guess I should also mention being very careful with the fuel line connector under the back of the tank and don't rest the tank on that connector. They have been known to break and are a both a pain to replace or fix and can be expensive if replaced. RicZ came up with a great idea on how to fix it with a metal tube as a sleeve and some epoxy if I remember right.

Seriously; don't be afraid to work on your own bike and it's not a bad thing to ask for help. I see you live in the Phoenix area and there are lots of Vic riders in your area who frequent this forum who can help.

have you looked to see if hose is on the frame nipple. With seat off you should see it.
If it was leaking out of the hose the leak would be farther back.
Like Boggie said check primary bolts

Well, I'm going to tackle this project on Thursday and will take some pictures and I guess I've been using the wrong terminology. Its the crankcase vent that's causing the problem. Will update later in the week but thanks for all the input.

Ok, I wish I knew how to relabel this post because its all related to the crankcase oil breather tubes according to the "Engine, air Intake" parts list. I took the air cleaner out to clean the oil I was told would have accumulated in the air box area and didn't find any. You can't reach far enough to the rear to reach or see the Rear oil tube connection inside the air box. But you can clearly see the front one that comes up from the Idle Air Control ( IAC). It comes up from the bottom of the frame just in front of the rear cylinder. Inside the air cleaner box it was very clean but the outsides of all the oil breather tubes where coated with oil residue and all of the connections were tight.
It must be blowing back out of the tube seal connections but I don't how or understand why the inside of the tube would be clean???

Since I couldn't find any oil in the rear oil breather tube or inside the air cleaner box I just decided to super clean everything with brake clean and Q -tips etc. Maybe at one point I had over filled it with oil which they say is the cause of this problem. I cleaned it with an engine degreaser a year ago and it just started dripping again. I've been at the half way mark on the dip stick. Which is only 1/4 QT low.
But since I've taken the gas tank off I now know there's no way to clean it properly by just spraying degreaser up in that area and hosing it off. Some of it MUST be scraped and wiped off so you have to remove the tank.
IT will take two post to post all the pictures.

FYI; I never did see part #10 on the parts list.

follow up photos.

The first pic shows the hose coming from the IAC (Idle Air Control) on the right side. Which was really dirty (pic taken after it was cleaned) on the outside but as you can see, where it comes up inside the air box area its clean.

The third pic is of the IAC on the right side and its the middle hose that you see over on the left side going up into the air box.

say maybe the hose is not sealing tight. So put a zip tie on nipple and hose and see if it stops
