Coupla dumb questions I already predict the answer to. Is anyone really in 6th gear by 37 mph!? Does anyone really not downshift until 17 mph and then from 6 to 1!?

I have no problem with sustained rpm limits to 600 miles and 1000 miles but this other stuff boggles the mind.
 
Yah, that manual is funny on that topic! I say go by your prior riding experience........take it easy, somewhat like on new tires, and just watch the rpm. You know how it should sound/feel for changing gears based on having the FZ6, right?
 
Yea, those numbers in the owner's manual are funny. Just ride it like you did your other bike. However, take it easy the first few hundred miles with taking the engine to redline. That being said there's no harm is occasional brisk acceleration...
 
If i recall, its mainly because the cylider and piston/rings, are so tight on a brand new engine, that if you just hit the trottle it will shave your rings and cylider walls, causing unessiary ware and damage. It's like the piston rings are still sharpe and need to be turned in slowly. When you start a brand new engine it doesn't really what to take off like a looser ran in engine. It takes several hours of just letting it idle before it will start to loosen up for the first time. So just let the engine idle, that is probably the best for it.

Actually idling is by far not the proper way to break in an engine. You want to vary the load on it and get some pressure on those rings to seat them properly...

Exactly right. A varying load on the engine, running it up through the recommended rpm range, and avoiding constant rpm's is the key to a well broken in engine. Babying the engine with low rpm's and little load on it does it no good and you run the risk of unseated rings and a poorly broken in engine. Don't abuse it, but rev that engine and run it through the gears.
