You have whats commonly called 3 holes. Engine, primary, and tranny. Some use different oils in each one, but some use same oil in all three. Your choice, your bike, your money.

As already stated you can (and many people do) put 20W50 in all three "holes" (also called bags or boxes). There are discussions for years on what is the right thing to do. You do what you feel is necessary. Redline makes a V-Twin power pack which has 3 different oils for engine/tranny/primary. If your bike is newer (not sure when this started, maybe 2010) you need an extra qt. of primary oil b/c it calls for 38oz. The Owner's Manual will give you a good idea of where the drain plugs are and how much oil to replace with. If you feel comfortable doing so, you can save a great deal of money doing the oil service yourself.

That information should be in your Owners Manual

Kilokato,

For sixty bucks you can buy the service manual and get to know your new toy a little better. I know I've enjoyed doing all my own service work and its saved me a good bit of cash at the same time.

That would be called the "derby cover"
