Although yamabond is the preferred compound, I've had mine off several times and used black RTV. Toyota, honda and GM make very similar product to yamabond that work equally well.
BIG CAUTION: use the minimal amount and keep it thin towards the interior (nearly invisible) and only paper thick towards the outer perimeter of the sealing surfaces. The reason being - excess can fall inward into oil circulation and plug oil feed ports.
You'll know if you used too much if: you mate the surface with firm pressure and then pull it away and see a big blob inside the engine. This can be done to a small test strip 1/2" long. So - MORE IS NOT better!
Mine is not leaking and when I'm done tinkering - I install the new gasket and good sealant.

I assume you are using a new gasket?
Curious. How many miles do you have on the bike ? I have 22k and I skipped the valve check in this year's prep.
Personally, when I have done engine rebuilds in the past, the only place I used any sort of bond was on the crankcase halves. Any other join has had a gasket and if you make sure the surfaces are clean and torque the bolts properly, no leaks should occur.
I can tell you that the "NEW OEM" gasket is stamped steal (or something) with a ridge in it. Its a crush fit gasket and has no soft rubber components. So if all mating parts were cleaned properly I would venture to guess a pure metal gasket will seep if not sealed with some form of sealant.
"PN: 5SL-15456-01, Gasket, oil pump cov" is not paper, rubber, and it contains no pliable soft sealants. Other NON-OEM gaskets could be of "another" material and not require additional sealers.
Me personally: any type of paper or porous gaskets gets sealed with either "Spray Copper Coat" or rattle can "gloss enamel paint". As this seals the pores of the material so it doesn't seep. And yes, I've rebuilt many engines with great success. Prep and clean up make the difference between a good job and lasting good job.
Hmmm, I guess I am old school when gaskets were made of GASKET material :spank:

A couple of years ago I dropped my bike on the left side in a low speed car park incident. The insurance paid for the fairing, tank etc. and the left side engine cover. After I had repaired everything (in the dining room LOL) I took the bike out and went to change the left engine cover. I leaned the bike over against a wall on the right bar end for a while, then undid the bolts. It took quite some effort to get the cover off, then when I saw the torx bolts holding the stator (?) I though "f*ck that" and just bolted it back on again. To this day, not a drop leaked.
Randy,
Andz, I believe, is referring to the LEFT SIDE engine cover and the torx screws that hold the actual stator to the outer, engine case...
