same thing i told those who test drove the car and did not feel it. Maybe they forgot that in my00-03 it also takes time for you to notice it. Once you have about 15k mi its when the car will rev smoothly and vtec transaction will be what is supposed to be.

 

I did a quick web search and found a good explanation:

"...As for break-in, proper heat cycling of the engine is really more important than rev range. Many parts in a new engine have internal stresses from manufacturing processes, which are slowly released by heat. If you took a piston out of your 13-year-old Ninja and one from your absolutely brand-spanking-new GSX-R and put both in an oven at 500 degrees Fahrenheit for half an hour, you'd be surprised at the outcome. The 13-year-old scarred and worn-out piston will look like it did when you put it in. The new piston will be warped and completely destroyed. The reason is that heat unlocks the internal stresses and allows the molecules of the metal to rearrange. The same process happens inside the engine during break-in, but the cylinder walls confine the piston. Many heat cycles later, the piston has relaxed and taken on the desired shape inside the cylinder.

I'm no expert, but I try to keep the break-in drives to a reasonable length (1 hr.?), then let the engine cool down before starting another heat cycle.

 

sounds like a good idea, the question is how hot can the piston get going from 0-5000rpms i always thought to do proper heat cycle on break in one must rev to 5k only but do it in a fast paced manner. thus increasing heat in the engine cylinder. What i do know is that you dont want to stay at a constant rpm, you wanna work the gears and revs.

 

Sound fun and good read.
