Just fit a new cylinder, piston / rings and big end bearing to my '05 WR450.

How many km's / miles do you reckon it needs to be run in for before I can give it the berries?

I broke mine in by riding it completely stock with throttle stop in for a 20 miles ride with a couple rests in between. This way I really couldn't go past half throttle, but I ran it fairly hard because I hear this seats the rings better. Every one has a different opinion. Mine made sense to me.
