Start it up and warm it up only long enough for it to get to a rideable temperature. On a carby this might be 10s on choke, on an injected due to better fuel mixing probably by the time (a late injected...) will have come down from it's initial fast idle.

When you ride away be gentle and smooth for the first 1 or 2 miles as it's this initial warm up that seems to make a good difference to tyre wear.
