I'm with _you_, Dave. I've always worked on the premise of: _Never_ lug
an engine! Break-in should see 2000 - 3500 or 4000 rpms at part throttle
only; _never_ wide open throttle (WOT). The only times you would see less
than 2000 rpms is when starting out in 1st and coming to a stop. Hill
climbing in high gear puts a tremendous strain on an engine. The older
T-types, I understand, used to break cranks under those conditions.
My 2nd B-GT was "broken-in" like the above, and when I sold it at about
82,000 mi., did not use a drop of oil, no bearing or tappet rattle, etc.
Much luck with your decision! :-)
