Not a stupid question.
As I know it, Sealant generally not needed when good gaskets are used.
With Gaskets being expensive, many make their own out of purchased (rolled) Gasket Material , Cereal Box's or Manilla File folders (trace outline of cover ...etc.).
hope this helps

I use the high temp black stuff on any gasket I don't plan on getting back into anytime soon. It's a real pitta to clean off. Just be carefully on the amount you use as you don't want excess squeezing into the engine where it can cause problems.
I usually apply a thin coat with my finger to spread it out.
But, good gaskets & a good clean non knocked surface shouldn't require it.

thanks i didn't think so with the factory type gasket. i thought maybe a little just to hold in place with the help of the alignment pins.

I use bearing grease for that. Just a dab will hold the gasket in place while you line everything up.

I normally don't use any kind of sealant on the Vulcan, but I made an exception to that for the bevel drive cover. It is difficult to install that cover, because you have to install it against spring pressure from the damper, and line up the driveshaft splines at the same time. The first time I tried to install it, I destroyed a brand new gasket. I got another new gasket, and used Permatex gas resistant black RTV sealant to glue it to the engine. I let it sit overnight and cure. This time the cover went on fine. This sealant is not like the usual silicone RTV stuff. It dries harder, and does not feel at all like cured silicone. I don't plan on ever removing this cover again, so I wasn't too concerned about how hard the stuff would be to get off.

I am a motorcyclist, NOT a biker.
