I too just got a ZX6R and in the break in period. I also found it hard to keep it in that 4K rpm range all the time, but can keep it under 6K.
I talked to the guy at the dealer and he said that the 4K range is just a manufacturer's suggestion and that going a couple thousand RPMs over during the break in period isn't going to hurt.

I believe that they are trying to say you should shift up according to your speed to keep the RPMs down as much as possible instead of racing the engine at high RPMs in a lower gears. Basically you want to work all the gears through. So at about 50+ mph you should be in 6th and probably be in the 6k rpm range.

DemonRR's right! haha. But, IMHO, the 'right' way to break in any engine is to use it exactly like you are going to use it after the 'break in' period. If your riding it like a granny, the piston rings are not going to have alot of pressure on them and thus wont seat as well as if you rode it like a real man. I could go into all the specifics and science, but I wont. Only other recomendation I have would be to use conventional oil for the break in, and then switch to synthetic after.

I'm sorry,but I'm gonna have to disagree here. I say break it in like the manufacturer says to do.

Do you honestly think that you know more than the engineers that designed and built the bike? Personally, I'd listen to them before a bunch of random guys on a website forum.

Yeah, your probably right zxrider. I know theres a whole bunch of people that stand by the manufacturers specs, and a whole bunch of people that swear by the concept I talked about. Its just what I choose to belive. I had it explained to me by a few mechanic friends, and it made alot of sense to me.

But Im not one to agrue about such things

Ill ask one of the mechanics that explained it to me why the manufactures tell you to take it easy, just for kicks.

But you do raise a good point. If you can engineer all these kick-ass motors, you must know what the hell your doing

as long as you don't race the engine through the lower gears and and don't stay at the same RPM's, you will do no harm to the rings. Taking it easy causes the ring to not have enough pressure all the way around the ring to seat properly, causing the the rings to leak into oil. Which leads to the oil becoming contaminated thus robing power and causing more wear in engine. I never go above 8k on my machines the first 1k miles and those rings look better than my brothers, who likes to follow word for word in the manual.

The bike comes with an owners manual and usually all the Kawasaki's I have seen usually require a 1k mile break in.

I recommend reading the owners manual and see how they say to break it in. I usually follow or just a very little bit harder than what they say for the break in period.

I agree. Back in 1998 I had a new ZX-9R and I worked at D&D Exhaust back then. We dynoed my ZX9 when it had 700 easy miles and changed the oil and filter and made a pull. We did it again when I had 1500 miles(changed the oil and filter 2 more times) and it gained 8 HP.My co worker had a R1 back then he too noticed my ZX9 ran harder after a 1500 miles. I have been Drag racing bikes for 30 years I would Not Drive it Hard until I had driven at leat 600 miles and changed the oil and filter.
