Unless of course the cold start loop richens up the emissions required lean spots at the 3ish ta 5ish rpm's ???

It would either be fuel or timing (or both). From the sounds of it, the extra power that is available for the first minute or so of cold run sounds more like timing than fuel enrichment, doesn't it? So if the bike already runs fat, psyching out the computer to think it is still too cool for close loop would run a different timing map?
Give the bike about 6 months, and everyone will have found the little ECM tricks, etc just like a few little things that were done to the 12R.

The cold map makes this thing way faster in the low band...seriously faster, like it's not the same bike. It easily outpulls the Busa in "cold mode".

That'd go a long way in my book. Low end is the only thing lacking, performance-wise. I really miss it around town and, especially, riding two-up. Surely, somebody's working on it...

All theory here of course but I would *cough* think *cough* that there would be some pinging present if timing was altered (likely advanced in order to get to mormal temp quicker) that the bike would ping under hard accel conditions - anyone have this issue when checkin out the cold runs?

No pinging, but sputters a bit sometimes if driven while cold and not warmed up for 30 seconds or so...

Someone that had dyno a zx14 some time ago said it was lean on the bottom and crazy rich on top ....ecu is making it fat when cold ......I could see Kawi doing that .. good cold starts and lean it out when hot for the EPA sniffers...... .....I bet someone makes a fix real soon....

If you guys really think it's timing, why not put the power commander ignition module on? That's what Ryan put on his and he said on another post he didn't have the 4,000rpm problem, they are available on the power commander site, just the fuel injection remapping module isn't yet and I think Ryan has a ignition curve posted already, but for a Muzzy pipe, I picked up my bike today and now I see what everyone is talking about, thinking about get the igntion module soon and trying it out or contuie to wait on the Brock system.

Fastestbusaaround,
Have you had a chance to test your 10r with the Brock setup yet to see how it works? I going to go with a Brock system on my 14 and want to know what you think?
Thanks!

I noticed on Brock's zx14 Dyno run it shows the 14 way lean below 5,000rpm so maybe the cold start enrichment is what is making the bike run a lot faster until it warms up and the computer pulls the fuel back out, what do you guys think?
