Moderate Oil Leak

I bought this bike a little over a month ago and have been riding it regularly since. I noticed that it had a small oil leak when I got it but the guy I bought it from said that it was less severe than it actually looks. I don't know anything about motorcycles as I chose this one as my first motorcycle. I come here for help because I think maybe someone here can identify this. Maybe someone has had the same issue before. It's a 2005 model and as far as I can tell is totally stock. My brother went to school for engines and he told me from looking at it, that he thinks the leak is coming from where the front sprocket goes into the engine? If that is so then why is the head and everything below it soaked with oil. The plug, chain, and chain-guard is soaked with oil, as well as the plate that is on the bottom of the engine is holding oil and drips. It is slinging oil back onto the tire a little and I am afraid it's going to cause me an accident. Please take a look at these pictures and tell me if you think that it is going to be worth getting it fixed. I have an appointment scheduled to get it looked at by World of Yamaha but it's not until the 20th. If it's not going to be worth it to fix it (money) then I'm not going to get it fixed. I only paid $700 for it and the guy I bought it from doesn't know anything about bikes either, so I think I got a good deal. It runs good and I haven't had any problems out of it except for this and the gear will sometimes slip from 5th down if I'm really giving it hell.

When they're like that I use a scrub brush and what I call "Tide Soup". Good old Tide laundry soap mixed to a milky, soupy consistency. I brush it on and scrub it into all the nooks and crannies with an assortment of toothbrushes, scrub brushes and backbrushes I keep for the purpose.



Rinse it off, rescrub it with a realy foamy, concentrated mix of dish detergent and water dish and it's usually like new.



Gunk and a pressure washer usually requires multiple applications, It's easier to use, but tends to lift paint from cylinders. The secret to using it cheaply is to brush all the nooks and crannies with it as well. The problem is that it dries too quickly and you gotta work fast.

Kerosene and a stiff, long-bristled paint brush, followed by dish soap and Tide in water and the same paint brush, followed by clean water rinse. Kerosene softens baked-on crud, dish soap cuts grease quite well, Tide cuts dirt. Each helps the other out. Soaps kill kerosene, so use the kerosene first to make a gooey mess, then the soap solution to clean the mess off the engine.

You guys are saints for walking into this degree of diagnosis and cure. The only thing you didn't do adequately is to tell the man to turn off his hot water heater pilot light. With that much gas flowing through the system, its a walking (rolling) bomb. Me, I think he needs a real mechanic, and not a digital media coach. JMHO. But good onya for trying. Tom
My applications for sainthood are held up in commitee. Put in a word for me, will ya?




Never hurts to put the info out there. The first time this happened to me was almost 40 years ago. I was firmly convinced that dinosaur cells were regenerating and reproducing overnight in my crank case. Some old geezer put me wise, or I'd still be scratching my head. I ain't the sharpest tool in the shed.
