Isn't that a little like getting towed around Indy for the last 12 laps
in order to be classified as a finisher? In all seriousness, that will
give you all the right stress and wear in all the wrong places. We're
also talking about the heating (and subsequent cooling) of parts due to
actual running. First do all the tuning repair work to get it running
and then worry about the break-in. You won't hurt it by letting it sit,
and you won't compromise the process by running it a bit to get your
tuning right. The extended running at 2000 is not a magic spell where
you have to follow the recipe exactly, but just a guideline. They are
just concerned you'll run it for 30 sec. and then park it for two days
or that you'll idle it extensively or "lug" it up hills or in traffic in
that critical first hour. Make sure it warms up ALL the way, cools off
completely (and then retorque the head) and don't make short runs (less
than a full warm up) the first two weeks. Jarl
