Hello Bryan and welcome to the forum. I'm going to suggest that you get a service manual for your bike because I can only give you general ideas about servicing your bike. Now I'd use Shell Rotella 15W40 as it's only $12 to $15 at Wallyworld for a gallon. (Don't use automotive oil) Then I'd check NAPA to see if they carry the filter. Place the bike on it's center stand. Remove any plastic that's in the way. Locate the bolt at the bottom of the engine. Place a suitable container under the engine and remove the bolt. Allow the oil to drain. Locate the circular cover that has a bolt through the middle of it. It could be on the front, side or bottom of the engine. This cover has the oil filter inside of it. Remove this bolt (don't lose any little springs or other parts) and the filter. Reassemble and add oil until it's ¾ the way up the sight glass. Run the engine till it's at operating temperature. Check the sight glass again. When the engine is hot it should be ½ up the sight glass.
People say I'm stupid and apathetic. I don't know what that means, and I don't care.
Always wear a helmet, eye protection, and protective clothing. Never ride under the influence of drugs or alcohol.
