I always just ride normally, but gradually raising revs keeping it all smooth, make sure you go through the entire rev range, keeping off the limiter though, change oil after 500 miles, then your good to go.
IMO, but no doubt this will raise a debate
My ZX6r came out the crate got 100 miles on it, changed oil, and hit the track. was fine and as the miles ticked up more and mpre power came, sold it with 18k on it, never missed a beat.
