Took the timing cover off the right side of my '81 1000G last night and there was the slightest amount of oil pooled at the bottom of that recess below the timing plate. Is my right side main seal leaking ever so slightly?

I believe bwringer has written on that project. IIRC, there was some trickiness regarding which direction to install the seal.Dogma

How to get a "What's New" feed without the Vortex, and without permanently quitting the VortexComment

Yep.
Easy to replace, but the new seal has to go in what looks like "backwards", with the metal side facing out. Guess how I know this now... I built an engine with the crank seal the wrong way around. DOH! It lasted about 10,000 miles somehow.
Anyway, after removing all the ignition stuff, I levered the old seal out with a big screwdriver, then pulled the new one in with a big socket and a long 8mm bolt and nut threaded into the crankshaft. Pretty standard seal replacement if you've done much wrenching on cars. Easier to get to than on most cars, really.
I believe I coated the outside of the new seal with a bit of case sealer just in case. And, of course, I made sure the seal bore was nice and clean and dry.
The seal is marked with a tiny little arrow showing the direction of rotation. Make sure you respect the arrow...
No rush -- these engines don't use any oil pressure, so it's not going to turn into a gusher suddenly.1983 GS850G, Cosmos Blue.

I've noticed the same thing; I'd leave it alone.

Thanks for the tips. Yeah, I won't mess with it unless it starts to drip on the outside. I guess for now I can just periodically take the cover off and clean it out.Current Bikes:
