slight oil weep from valve cover gasket...

GRAVITY?????
How does gravity pull the oil sideways through the seal?
The ONLY way oil is getting pushed out of the valve gallery is if the pressure in the valve gallery is higher than the pressure outside the valve gallery. The valve gallery, actually the whole motor should have one bar or less of pressure inside the cases. Less is better, negative pressure is best.

Honda gave you a nice big thick soft neoprene gasket that compresses to seal the valve cover so there should be no "microscopic gaps between the gasket and mating surfaces" if you apply the recommended torque to the valve cover bolts.
So no need for silicone.
As long as the "washers" are not so flattened to allow the bolt to bottom in the hole, they weren't your problem in the short term. The purpose of those "washers" are to isolate the valve cover from the vibration of the valve train (in case you didn't notice the valve cover bolts go into the cam caps). In the long term, if those "setting rubbers" (that's what Honda calls tham) are flattened out and hard, the vibration would be transmitted from the valve train to the cover and then flatten out the big o ring and loosen that joint, causing an oil leak.
Honda does not call for any sealing compounds on that gasket, but that big "o ring" never sits flat in the groove so I use Threebond to glue it into the groove before I install it. When you remove the valve cover again, the "o ring" stays in place in the valve cover and you never have to putz with it again.

Not sure why I feel compelled to respond, but I will briefly;

I did apply the recommended torque, and in the correct sequence.
Yes, Honda gave me a thick rubber gasket.
The service manual itself calls for RTV silicone around the halfmoon cut-outs and corners.
Yes, as I stated above, the washers were flattened with age and time.
Well, I removed the gasket, because, when I removed the valve cover, it partly disconnected from the grooves.

And yes, I fixed the problem.
 
It's an awesome, peppy bike. Just gotta fix my forkseals :(
But yes, i'm still riding it.

Let's see some photos. Big Radian fan here.
 
It was. I'm sad to say. But it has had some hidden problems, like the exhaust "H" mount was barely hanging on with internal rust. And later on an accident that the bike hasn't fully recovered from. It took me 6 month to heal up. So unfortunately exhaust + gauge cups are rushed up. Plastic is brittle on the gauge mounts and i suspect actually are broken off and only a windscreen has been keeping it in place.
Much work ahead to fix it. Cups are made from unobtanium thought, so will have to find an alternative
 
I love that colour Radian, same as what I had. Want a free OEM air filter? heh
 
Holy smokes that person parting out, add up and you can buy several used radians for that price.
I'm interested in cluster + exhaust. Both asking prices are 250$ that's unreasonable

True, but as they say: "beggars can't be choosers". :) If he's fairly local, I would inspect the parts in person to determine overall condition. Photographs often never tell the whole story. Perhaps you can work him down to a lower and more reasonable price if he knows you're a Radian owner. Often times, these guys have no idea what's a fair price, and are happy to be "adjusted" by somebody "in the know". Maybe not. But, worth a try.
