Well my break in periods where usually 500 miles.. on my GSx1300 and GSX1000 i rode the first 500 miles under 7k rpm, but after that i rode it no more than 9k for until 1000.. and after 1000 i changed the oil.. i would occasionally take up in high rpms durings my rides but when in neutral.. just a quick rap on the gas.. so far, they ran fine.. after the oil change, you'll notice a world of difference.. hehe
