A bunch- I've got one in a crate and also have a 450XCW motor sitting next to it. I'd guess the 690 motor is ~20lbs more, although given I don't have a scale and am guesstimating the weight of the crate, that could be complete malarky.
On the flip side, I believe that weight goes to things that count. A 690 will go, as Jenny said, a very long way with no maintenance at all, where a 450XCW really wants its oil changed often to get decent life from the engine.
Curious about FI vs Carb as well!
