    Unleaded fuel

    Hi folks,
    got a 1983 sei 900.
    does anyone know if these had hardened valve seats or do you need to use a lead replacement additive ?
    thanks for any input you may have.

    Hi you need lead replacement and you can have the head converted. The seem to run ok on with lead replacement additive I even use the Tank insert type as well! I will look up the make of tank insert!

    This is the fuel catalyst I use but the choice is yours.
