Hello, I am new here

[cbRider]

Hi, I just bought an 81 CB750F Super Sport. I don't have an owners manual and the Clymer Manual is still in transit. I am wondering what grade oil you all use and where do you get the oil filter? I have quite a bit of work ahead of me getting the bike into shape.
Thanks

   Welcome to the site! I use 10W-40 in my 75 but check your Clymers when you get it. You can get all kinds of parts still from oldbikebarn.com, hdlparts.com (OEM), bikebandit and some others. This will include filters, tune up kits, engine covers and so on.    Paul

Nothing that says 'energy conserving' on the label.
