I'm replacing said gasket to hopefully stop an oil leak from the side cover of my S3. Do I need to put any kind of sealant or anything on either surface, or is just the new gasket sufficient? Thanks

Triumph recommends assembling dry, making sure that both surfaces are thoroughly clean. Tighten the bolts in a cross pattern & in stages if you really want to do it by the book.

Cheers, HTH,

Thank you Kit

Use a careful technique while removing old gasket material from mating surfaces. Any nick or gouge has the potential to become a leak later on down the road. Snapon and Matco sell professional scrapers. You can get by with a good quality windshield ice scraper so long as you sharpen it with a file or sander. Another safe scraper can be made from copper tubing by flattening both sides of one end. Then heat that end for a few minutes with a propane torch before quenching it in a bucket of cold water to anneal it. Resharpen it and scrape away carefully.

Nice! Wish I'd known about those scraper options when I was working on the Trident engine.

Should that fail a very very very light coating of Yamabond should do the trick. I use it on the Norton which is notorious for weepy joints and it holds the sludge in

I have used just some silicone and it seems to work well..

Thats one way to do it.
Most manufacturer of any type equipment will usually specify that gaskets to be installed without any type of sealant. Sealants can cause gasket slippage and torque problems. If a sealant is deemed necessary, most mechanics will use a non-harnening one such as the Yamabond or the Hylomar type.
Having said that, I realize there are many people that believe in using silicone on gaskets and usually get a way with it. I won't do it, but that is just me and my opinion.

Using silicone is just what a few mechanics said, they said that triumph uses it when the bikes are built...idk...
