If you have a service manual, read it. The covers on either side of the engine do not have gaskets. The manual says to use Three Bond 1207B or equivalent.
Section 10 for the left side (alternator cover).
Section 17 for the right side ( Right Crankcase cover)
The books shows where to put the sealant.
Be careful over torquing bolts on this bike. For instance, the top shock bolt will snap very easily if overtorqued even a small amount.
About to attempt this job. Looking at the manual it says to apply sealant to the wire grommets. Can’t tell from the pics but is it both sides? Or just place the grommet in the cover then apply sealer to the part sticking out of the cover. I see some sealant goes on part of the case and all the way round on the covers as well.

On the grommet, you want to put it around the sides where it will contact the edge of the cover and the engine case. And remember, use a thin film or bead everywhere, it doesn't need much. If you bolt it all in place, and any squeezes out, it's probably squeezing out inside the cover, and there it can get into the oil supply. Take it apart, clean it off and use less this time.

Sounds good. How long after do I wait before I can ride it? Dry time I guess?

Pretty quickly. I might wait an hour or so.
RE: Weak Crank Case Bolts? - bertypower_imp - 09-11-2020
Well, I did it. Went well. So I used Hondabond HT. Says to wait an hour before surface hardens. 16hrs to set in like rubber. Should I wait the full 16? Or just a couple hours. I can’t imagine the dealers are holding a bike for 16hrs before pickup. Lol. Thanks for all the help!
RE: Weak Crank Case Bolts? - peterbaron - 09-11-2020
Best is to follow the instruction.
We, at our car dealer use the Permatex Gasket Maker....and it says allow 24 hrs to fully cure before filling fluids...
Sometimes we wait much less time (customer waiting/rush) before filling and no leaks*
The trick is, after application and finger tight let it dry for 1 hr before torquing to specs...*
*don't blame me if you use a short cut and starts leaking
RE: Weak Crank Case Bolts? - bertypower_imp - 09-12-2020
Update: Did it. Test drove today. No leaks. Thanks for everyone’s help and 2c.
Note: there was hardly any sealer on the right cover from the factory. The left side was removed before. (Probably when the tip-over happened). There was a lot of the original sealer still on and whatever was used to redo it. However the bottom bulb. Where the slow leak was didn’t have much sealer at all.
The most important things IMO are getting those surfaces as CLEAN and degreased as possible and making sure you have a consistent strip of sealer. Had to use a combo of Rasor blade, finger nail, break clean and tweezers to get all the old junk off.

You're quite right about the cleanliness of the surface. I save old toothbrushes for this. The sealant not only keeps oil in, but water out, as pressure washers can blast at 1000-2500 psi, more than enough to penetrate your skin.
RE: Weak Crank Case Bolts? - Inhouse Bob - 09-12-2020
I'm late to this conversation and I'm glad it all worked out. Is it possible that the previous owner over-torqued those bolts after the accident and while trying to stop seepage for the sale?

Well, I think he dropped the bike. Got a leak. Sealed it and probably thought it was fine. Honestly, it wasn’t leaking enough for me to catch it on the inspection. It also never leaked enough parked to even get more than a drop. So I think it just went unnoticed. He was upfront about the drop before I saw it. Only noticed it after a few hundred miles.
