Oil Leak

Hello everyone,

I posted this on ADV Rider, asking for suggestions, ideas, recommendations. My WR250R has developed what I think is an oil leak. It has 60 miles on the odometer. The oil seems to be coming from one of the bolts of the cylinder head. There are two bolts visible on the right side of the engine, when viewed from the riding position. The front bolt on this side has developed a sizeable leak. On the photo below, you can see the oil gathering around the base of the bolt/washer, and it was running to the side of the engine. I wiped the top part of the runoff to the side with my finger. There was also what appears to be few drops of oil on the header heat guard as well.

My question is:
Has anyone experienced this on their WRR?
If this was a manufacturing problem, where that one bolt (as far as I can see it is the only one leaking) is the only one not torqued enough, could this have warped the head?
I'm taking this bike to the Yamaha dealer. What precautions should I take regarding how to guarantee the best possible care?
Anything else?
I sure would appreciate sugestions, recommendations, etc.
Thanks guys!

Someone on TT had that very same problem, but I think his was due to having too much oil in the crank case. If yours only has 60 on the ODO....maybe they filled it too much during PDI.

Oil level is within specs.

With only 60 miles on it I would be right back to the dealer with that thing. Have them check the torque on the bolts that are visible only. No sense in tearing into the engine to torque the other two bolts unless the leak moves to the left side. It may just not have been torqued properly at the factory. Have you run the bike to where it gets hot or overheated it? If not then don't worry about it. Warranty will cover a leak like that seeing as how you have such low mileage. I seriously doubt the head is warped. Do a search over at TT. There was a lengthy thread over there about an oil leak similar to yours.

Thanks Mwakey.
My plan is to take oit to the Yamaha dealer. I want to know what to expect from them though. I searched on TT and the only thing I found wast a reference to a head gasket leak. If that is the one thread, then it is about something different than what I have. My bike is not leaking at the gasket, but through one of the cylinder head bolts. If there is something else about this type of oil leak on TT I would like to know how to find it.
Thanks again!
