I just bought a 636 a week ago and dont know how to break this thing in. Kawasaki says to keep it under 4000rpm for 500miles then under 8000 for another 500. They dealer says keep it under 8000 just for the first 500. Friends say that i should ride it like i plan to for the life of the bike. They say if you give it hell beaking it in it will perform better. I would imagine it needs some time taking it easy, but 1000miles seems long.
