New ZX14 Cylinder Head
Okay, so i dont know what they look like but thats my reason for this post. The 06-07 had not so great intake runners on 1 and 4. 2 and 3 are straight in like the ZX12 so my hope is someone like Brock whose testing one now might look down the intake runners and let us know if they straighten them out or if they are sitll on an angle. The ZX 12 are all straight in.

And the ZX14's aren't? Same frame design, no reason not to have straight intake tracts,. where did you get this information on the ports??

In fact I think most the Ninja's intake ports have been fairly straight since the 1984 Ninja 900. It drove the camshafts from the side of the engine instead of the middle for that very reason.

No they're not straight on 1 and 4,like Rich Craft 1said. The man who ported my 12 and my 14 heads said it was not a good design change on the 14, but he got them to flow the same with some work. 1 and 4 are curved like maybe the spacing on the throttle bodies are closer on the 14,I never checked to see.

New Zx14 cylinder head
Bob Carpenter told me back in 06 the ZX12R head is a superior design.

I'll bet CompetitionCNC will have a nice fix soon. Keep us posted.
Bob C seems to have it figured out according to his website.

I WTB a 2008 ZX14 cylinder head, but I can only find 2006 year model ZX14 heads, is what I have heard in the press true that the 2008 year model ZX14 cylinder head is a bit different, enough that I would be stupid to try and put it on a 2008 motor? I appreciate the help! Cheers!

Yep, the 06-2011 heads are all the same.... Lets say gen 1
We will find out about the gen 2 soon. I'll be digitizing the ports as soon as Rickey gets one.
Then we will know whats what. I'll post 3d Port models and some other digital data and other cool tidbits as soon as I can.
I highly doubt that all 4 intake ports are the same thou. The outers will still be angled in I'll put money on it. The zx12r head is truly a superior design as far as flow and velocity. Its still better than any busa head gen 1 or gen 2 and better than a zx14 head.

I always liked the power the zx12 made, same as my 14 did before the head work, just 10 lb tq less. True hp always comes from the cam/head, thats why unless you made the gen 1 busa motor even bigger, the 12 always made more hp. Too bad that motor was in the wrong bike.. I still dont understand why Kawasaki didnt keep the same head and cam design when the did tbe gen 1 zx14.

EXACTLY the ZX12 just felt like a racier more high performance motor than the ZX 14...........sure the ZX 14 has more torque and is faster but the ZX 12 made power right to the limiter at around 12K while the ZX 14 stock felt like it flattened out at 9500-10000 RPM's.........the ZX 12 just felt like it revved WAY more and was in a much higher state of tune than the ZX 14.

I never got the ET my 14 did, but I always had a 30 mph backhalf and I weighed 200 lbs back then. I would 1/8 mile 118 and 1/4 mile 150!

Well this is good news because now I can buy the 06 head and not worry about messing up my 08. I low sided my 08 on the right which did damage to the right upper mount on the cylinder head. First I am going to see about just getting it repaired, but I will also get the used but good condition 06 head in case.

Did you have frame sliders?

Yes. Shogun no cut. They were the chrome polished aluminum type. I knew better. I read what would happen. I'm stupid. I learned my lesson. I really was pissed at first at having sliders at all, then I started to look at the "better" alternatives like LSL, Speigler, Konstruk-D, etc where they mount 2 or more locations. I am going to get the Spiegler LSL type now because they look to be the best thing next to getting race rails. I have full coverage comp/collision.
I'm doing all my own labor and work myself. The lateral forces from the crash cracked both front upper motor mounts and also the right side slider ripped a bit of thread clean out the cylinder head mount on that right side. There is enough material and thread to fit a longer bolt through though. Since I'm doing my own work, the insurance company is just cutting me a check for 3500+ usd and saying it's all repairable not totaled. They are also going to pay me 50/hr to do the labor so that pays for my deductible right there since it was 500 usd.

Lots of argument both for and against sliders I don't have em but so far haven't needed any. I would think the plastic ones that will grind off or break before the head are ok.

Well there isn't really or should not really be any argument. It's either smart or dumb. I was dumb. It's also plain ol' common sense. The members who have pointed the obvious issue with a lever and leverage are the smart ones. I did not listen to them ahead of time and that is my fault for not listening to common sense.
If you have no frame sliders you are taking the ultimate risk. That is your choice, but don't make that choice based on the idea that frame sliders are more harm than good. That's inaccurate to the highest degree. Frame sliders saved my ass big time in repairs and damages not just to my bike but to my body. My right leg would of busted had I not had the frame slider for example. This is with the poorly designed sliders even. You should listen to those here who have suggested the Spiegler LSL or other sliders that have a larger mounting base rather than just using a single mount off the lower bolt on the upper engine mounts.
As always your mileage may vary in a wreck depending on what manufacturer and material your slider is constructed from, but don't go without them because you think they are more harm than good. There are poorly designed (shogun) and there are good ones Spiegler LSL. That's not an argument just the facts.
