Low end RPM pulls like a bitch
Well...I've tested this like 10 times now and it's 100% for real...during the 1st minute of warmup, even at room temps...the map isn't the same and I'm willing to bet there's absolutely no limitation on the power below 5k. She pulls away much harder than a stock Busa at 3k...it's staggering...in fact enough to lift it at 3k (did it) -- nothing I've ever ridden, including my 04 FJR1300 that I had (wheelies at 2k), pulls harder during this 1st minute warm up...no kidding. Power is awesome people...mind boggling. Now, who's gonna introduce the 1st mapping/ ECM fix for this puppy?

fba - Are you saying that each and every time you start the bike, that it acts that way? So for instance, if you wanted to really put the screws to someone at a redlight or the drag strip, you could simply turn the key off, back on, restart it, and go for it with full unrestricted power?

That's a special feature you're feeling, probably new to you. It's called KAWASAKI POWER.

No...it happens when the bike is started from cold...engine's got to be cold and not run for a few hours...but I can say with 100% certainty, this is by design and I'm sure the engine, without this restrictive mapping, has way more low end grunt than kawa is allowing us to gain access to. Something that will be changed with an aftermarket fix for sure.

I'd also bet that the Vegas bikes didn't have this restricted mapping...none of the guys here that rode them noticed this "flat spot" at 3500. I don't see it at 3500...I see it from idle to 5K or so. I'm 100% sure that the engine is putting out way more than the mapping allows it to...some sort of "Squid reduction mode" as Hayabusa12R said in another post. I know what I have seen and felt...this is not the engine power but rather the ECM mapping. If anyone tries what I tried in "cold mode", they wil see the same thing I have seen.

I don't know if the Vegas bikes where stronger ..But i do remember Rick G saying it will loft the front wheel at 4000....Mine will not do that at 4000 but it will at 5000....Have you guys tried like half throttle at 3000? Mine pulls harder at half throttle than if you wack it full on .. Doesn't the zx14 have two sets of butter flys in the throttle body?? One works with the throttle cable and the by the ECU? Damn if this doesn't sound and feel like the Vmaxs V boost...If it is we could just unhook it??

I also noticed that...at WOT it actually pulls less at low RPM....than at 1/2 throttle...and in cold mode, you can loft the FW at about 3.5K with a good hard twist...

If you look at the dyno charts on Brock's site you will see that the bikes are way lean below 5,000 so the cold start enrichment would put the thing closer to where it should be, hence the power gain at low rpm when cold, bike warms up and enrichment is removed and you have the weak power below 5,000 again, also it was posted the fist thousand or so bikes were held because they didn't pass EPA (late deliveries to everyone) and they were fixed in their crates and most likely remapped lean in the 5,000rpm range to help pass EPA, it all adds up if you really think about it, I tried the cold start test and mine pulls like a bat out of hell at low R's also until it warms up, low end enrichment is what's needed to unlock that range.

Torque?
I'm sure that most of you must remember some of the first ads from Kawasaki, stating that the low end torque was so substantial that taking off from a stop in almost any gear was a possibility?
It seems clear that some last minute mods were done, most likely for emissions, but who really knows. The advertised cr at 12.7 was dropped to 12, and it seems apparent there is some sort of mapping that restricts the bottom. Maybe someone needs to access the ecm and see just what temp this thing goes into closed loop operation. Does the bike have Cats on it? If it does, then the system will be plumbed to go into closed loop very quickly since the cats are subjected to extreme temps in a cold or open loop operation.
I have heard some of the guys like muzzy and brock stating the bike is very fat mid and top. I am guessing the system is going lean on the bottom.
Thoughts anyone?

It's probably because the mixture is rich for cold starting. These bikes are usually set up to run lean low down to get through emissions tests. I remember when my stock 'Busa was dyno'd we reset the fuel injection with a Yosh' Box because it was so lean at low rpm.
Hopefully that means a ZX-14 can be set to run properly, without the big dip in the power curve below 5000rpm. This weeks MCN test comparing the Kawasaki with the other big bikes was quite critical of the lack of low down grunt.

I remember people saying that mere mortals couldn't handle high horsepower bikes like the MotoGP guys ride... and that the MotoGP bikes had traction control and other fancy electronics to help them keep the rear tire planted without spinning. Maybe this is Kawi's way of giving us a bike with a bunch of grunt and power, but keeping us "safe" with SRM (aka squid reduction mode).
Oh well, the bike is still a ton of fun. And like someone mentioned in another post, it may even help to keep us shiny-side-up when touring in the rain

Screw that, I'll just ride in higher gears down low in the rain...gimme the power. I cranked the bike over to ride to lunch this afternoon, eased out of my parking slot and turned onto the service road which is about 250 to 300 yards long. Not realizing I was still in "cold mode" I hit it hard on the service road and damn if she didn't come up quick as a wink before I had even crested 3K. That gave me both fear and excitement, which is what I bought the damn bike for. Yeah, I like the civility, but if they could tone it down just a bit and give me a bit more "rush" I'd appreciate it.

Damn! Now I've gotta try it! The problem is that just to get out of my neighborhood and try something like this, it takes me 1-2 minutes, so the "fun" timer would already be expired

Just boot it out of the driveway....you would have like 30 seconds or so once you start the bike, not much more than that...just give it a 1/4 throttle twist, NOT MORE...or you'll end up on yer ass Matt, RW breaks free in a heartbeat at under 3K in this mode...just ask Squareman357...it makes a Busa look like a tank by comparison...you've been warned! :P
