i wonder why kaw says in the manual that you arent supposed to go over 4000 for the first 500 miles?? then 6000 from 500 to 1000? i just wanna feel some of the power that my ride has and at 4,000 - feels like im riding my 250

Keep in mind, "manuals" are reviewed by lawyers who want to minimize claims. The recommendations will be on the idiot-proof conservative side. Frankly, (and in total agreement with Drag) I think you need to go through the entire rev range (I'm not talking banging the rev-limiter or stupid crap) to get a good mating of the parts. Just make sure the bike is warmed-up, everything's tight, and don't overdo it.

You actually want to rip on the thing during break in. You want a lot of cylinder pressure which causes the rings to spread outward, thus shoving them into the cylinder walls and properly seating.

Well I would debate that. This is bound to happen over time, even if you go easy on the throttle, on the other hand metal parts are never alligned perfectly on assembly and putting too much stress on them from the start doesn't pay off. All that said, I think it is just as bad to rev the engine all the way when its still cold.

I don't believe anyone was saying the romp on it while it is still "COLD". Once it warms up, just get on it. I have an 07' ZX6R. I tried to follow the manufacturers break-in for about the first 15 minutes of riding... Staying under 4k is rediculous!! But with that said, I didn't wrap it out to the Rev limiter either. I think like alot of people have already said, just vary your rpms and take it easy!!
