Break In
Does it matter that I put my Yosh pipe on the bike while I break it in or should I stay with the stock for the break in?????

this is a very, very debated subject? I did mine by the book but on my 1361 I only had about 400 mile on her before I raced it......

I couldn't find Koz's original post on his break in method. It was basically the "heat cycle the engine, vary the RPMs and change the oil at 500 and 1K".
Here's a similar thread
http://www.bikeland.org/board/viewthread.php?FID=1&TID=355
This was basically how I broke mine in. I'm of the belief that if the rings and such have not seated by 800 or so miles, they probably never will. I will say that the 12R engine is pretty "tight" and really doesn't come into it's best performance until you get close to 2K miles. IMHO
As far as putting on a pipe, mine had 2K miles on it before pipes were even available, so I wouldn't have a clue. If I could have got a pipe, I would have probably waited, but I don't have a valid or technical reason why.

maybe I'll just take to some back roads here in ohio and break it in nice and slow....that way i won't stay at a constant speed and will be going through different gears but staying below the RPM range

XXXXXCellent ? You'd think with all the technology, testing, and such that someone could publish an authoritative primer on the breakin procedure. For now, I'm trusting the manufacturer's instructions from the all engineers @ Kawasaki who should know what they're talking about right?

We went by the book on john's bike (1000miles)...DID go 1k over rpms a few times here and there...
Someone here (EBD???) took his bike to the dragstrip with like 50miles on it so...it's up to you...
I honestly believe that the "breakin" is ALSO for the owner/rider of these FAST bikes 
Oh ya...I'd install the pipe when you feel like it...

breaking in a new bike, with all sorts of new rotating pieces is one thing, breaking in a refreshed racing engine is another.
I'm with KC on one thing tho, its the rider who generally needs more breaking in than the bike on a brand spanking new ZX12/Busa.

Well i'll just let the backroads of ohio break the beast in...nice and slow. I'm just very excited to get this pipe on the bike but i didn't know if it would hurt the bike putting it on during break in....

The number of miles is part of the equation. Heat cycles to me are heating and cooling of the parts. Other words Expansion and contraction of a part. The higher the revs, the more the heat, that is why everyone should go up and down the rpm scale as much as possible! Throttle up and heat the parts / swell the parts. SOme of the high spots will rub off and then when you slow down and the parts shrink they will not run any more! Do this enough times and even at high speeds, the swelling of the parts will not cause them to rub together and then the engine is broken in!
To make this really painful, ride your bike like a Harley rider. We have all heard them on the gas, off the gas so they can hear them rev up (Change rpms slightly higher) and then let off and hear the pipes! This is perfect for breaking in an engine a little at a time. To think in terms of what is going on, think of the smoothest past in the engine as the Rocky Mountains. Put two set together, one upside down and start rubbing them together. When you get finished, you would like them to look like the Plains in the USA, but really smooth will now be more like the Allegheny Mountains in the East, tallest peak around 2,000 feet, vs the Rockys where the average peak is over 6,000 feet high and many over 10,000 feet.
WHat does this have to do with a Pipe, nothing! Put your pipe on at any time, you must still ride the same way! I would suggest waiting for at least 500 miles and the first Oil change so that it will be safe to get a Base line "STOCK" On the Dyno! How else will you know if you are going forward or backward in HP??
