They stopped making motors that needed lead in the early 70s. An 80s should not need it. But I'm no pro.

The bike was designed to run on leaded gas and I was using an additive as well, at first. What a pain that is, but I stopped using the lead additive, and have used unleaded gas in it for the last 5 years, and haven't had any problems. It runs great and goes very well. I also run premium gas in it. I think I read once that the lead is supposed to keep the valve guides from scoring or wearing, or something to that effect.

No unleaded is fine, you should run 93 octane, but 87 is OK; I just find it runs smoother on higher octane..
