Valve Cover Gasket

Okay...this is likely a dumb question but I'm going to ask it anyway.

I rode the 919 yesterday and today and have been loving it. However, when I parked it at lunch today, I noticed a little shimmer coming from the motor. The little half-circle rubber pieces on the left side of the bike have traces of oil just around the outer edges. So...what's up with that. The right side has just the slightest hint of oil, but nothing like the left side.

Is this a common thing to see after the bike sat on the side stand all winter? Is it normal for just a small amount of seepage? I've got somewhere betweek 18,000 and 19,000 miles on the bike and have not done the valve check yet, but plan on it after I get block-off plates from Semi_Gray in a couple weeks.

Any input would be greatly appreciated.

it's a simple rubber seal there, check if your valve cover bolts have loosened for some reason. the seal could also be drying out some, it is a little unusual for something as new as a niner to dry out a rubber seal like that, but it could happen. when you check your valves inspect it very closely. the new gasket for the cam cover runs about 42 bucks.

My old 1985 CB700SC Nighthawk used to leak a little oil from the left side of the cam cover seal. It never caused any trouble. I would only worry if: (a) oil consumption is high; (b) there is whitish goo around the inside of the oil filler cap (evidence of water in oil); or (c) there is oil in your coolant.

That's just my 2 cents... I haven't noticed it happening on my 919.

Thanks for the quick replies. It is not consuming oil at a high rate by any means, the coolant looks nice and clean (although I'll probably change it just because), and there is no evidence of water in the oil. It also isn't smoking or anything else.

I'll check the bolts sometime this weekend.

Thanks. I wish I could change the title so I don't look like such a retard.

I think the p/c term is now window licker, isn't it? either way, we won't hold it against you. it's a gasket on the head. same difference!

FWIW I got 49.6k on mine and have removed the cover 3 times for valve checks and adjustment. I'm still using the original seal. Just put some black silicone around the half-moon area when you check the valves.

I think the torque for the cover bolt is 7 pounds.

If that's all it is to the leak, I'd take an old rag and wipe it off once a week.
