One full liter
This thing is going to be a rocket. You're going to love those big bores.
The break-in, as I'm sure Josh knows, is CRITICAL, and basically "sets" the amount of oil the engine will use over its life.
Tom Cutter, Snowbum, and others - to especially include this:
http://www.mototuneusa.com/break_in_secrets.htm -- (from our very own site, Links and References. . . ) give CORRECT INFORMATION about the break-in. You can definitely start a fight around this issue, but judge the sources for yourself. This is NOT your father's Oldsmobile, brother, and a lot more is known about the process of break-in these days.
If you don't want to read it all, just remember to ride the hell out of it, and back-off the throttle frequently. Frequent oil changes during break-in.
