Just my opinion based on my own experiences, no need for lead additive. Just use premium high octane fuel without alcohol if you can get it. I think in europe they call it RON not octane number.

This post says all USA bikes after 1975 or 76 were designed to run unleaded gasoline.

Valve seats are not aluminum, or at least not pure aluminum. They are inserts very resilient to wear, either iron or alloys involving copper and some aluminum..
