How old is your other zx6? If its a carb'd bike you won't have the "choppy throttle" which is a typical fuel injected bike carecteristic. My ZX6 is the same, and it has to do with ignition timing and fuel map, go back to a dyno and have a tuner to smooth it out a bit. Also on the PC you can calibrate your TPS zero point, try that.

My other bike is a 2010 zx6r (previous model) and I have been lucky enough to have had a lot of bikes that are fuel injected as well as carbed years ago....

I've also had a lot of the bikes I've owned tuned.

Sounds like a silly question but do you need the additional ignition module for the PVC to mess with ignition timing?

Did you change sprocket ratios?

My bike has the same damn choppy throttle issue, its especially annoying went exiting a turn or if I have to make any adjustments in mid corner while leaned over. Have you considered the Motion-Pro revolver variable throttle kit?

Yes, you need an ignition module with the pcv

I would try and see if you PCV tuner would write a letter to Kawasaki acknowledging that, they tuned your bike twice and still can not remedy the choppy throttle. You see, this is what worries me on a constant basis. Dealerships trying to back peddle their way out of addressing legit issues that come up from time to time with a brand new vehicle. Big question is, if you are covered under warranty why don't they look into the problem?
If all else fails, here is what I would suggest. Ask your dealer for your regional reps contact information, if you are unsatisfied let it be known. Keep climbing the corporate ladder until you are compensated or the issue is completely fixed. Best of luck!

That not correct. The PVC and ignition module are separate stand alone units on some models. For the 2013 zx6r they are separate as you can see here:

To me it sounds like a timing problem. Can you switch your PCV on/off? That could narrow it down to see if the spark can not keep up with the air/fuel change done because of the new map. If that is the case, yeah, the PC ignition module would be your only solution.

On a side note, I don't have the issue.

On a other side note, I have had the issue with a 67' Nova that I owned when I was younger. Once I got the RPM's up high enough, the bike just hesitated quite a bit. The solution was a MSD ignition control. I know bikes and cars are very different beasts, but all engines depend on air/fuel/spark for combustion.

BTW, at what RPM is this happening at? I doubt it can be a problem within the whole power band.

Copping over my reply from another thread, this is what I did to fix the issue:
.
--
I took the above advice, went and got the ECU re-flashed, removed the fuel cut on deceleration, even got the mechanic to do a dyno run for a new fuel map, THIS DID NOT FIX THE ISSUE, but were on the right track.
--
Mechanic did some research, found out this was a 2013 specific issue, something to do with ignition timings he told me, so what he did was overlay a flash from a 2014 zx6r ECU, and also removed the motor for the exhaust valve controller (Exhaust valves and servo motors explained)
--
Once this was done , issue completely resolved, bike is noticeably smoother, easier to ride, easier to get back on the throttle, and you will notice the engine braking is way less harsh, making corner entry easier. Another bonus is when you remove the exhaust servo motor, the exhaust now has a really cool burble, popping on deceleration.
--
Apart from that , thanks for pointing me in the right direction, if anyone is in Sydney (not many places that do ECU flashing for some reason), BC performance in smithfield is where I got the work done, speak with Kelvin, he'll know exactly what to do.

Did you remove the servo motor entirely or just disconnect the cable? Because isn't removing the motor will cause a CEL if you don't have the servo buddy?

I'm getting that harsh engine braking on mine and it sucks. Hoping this would fix it with stock exhaust.

I am in the process of tuning my 2013 with Woolich. I removed fuel cut and added some fuel. This made it better but the decel area of the curve needs work.

You can remove the exhaust motor and disable it through the software.

I have the same issue on my 2012. Exhaust servo removed, block off plates, PVC, and tuned and it still no fix. I have just learn to live with it but wish it wasnt there.
