It's a little late now, but, please ignore those breakin speed numbers. Those speeds were for the iron barrel engines and bear no significance to the UCEs. Just ride the thing without flogging or lugging the engine. It will be fine and much better for you!
As for corrosion, get some ACF50, and lightly spray the bike down. An occasional treatment, they recommend annually, with this will take care of corrosion problems. There is a video link in the New Product & Improvement Ideas category a ways down the thread list. It's good stuff. I never had any problem after I used it on my bike.
