I still can't believe how good Kawasaki nailed the QS on the 2021 Z H2 SE
I have had a few bikes with QS and they were no where as good as this one.
 Last bike was a 2021 Yamaha R1 and it's QS was no where as good and smooth as the Kaw.
I mean, Wow!

Yes, I love rowing thru the gears. They did a nice job, almost as good as a BMW.....impressive, well done, Kawasaki engineers.

I also have to say the QS is a blast. Being my first QS I was going into it sceptical but man did Kawasaki make me a believer. Getting spoiled!!!

Seems like I'm the only person who got their QS system built on a Friday after lunch. After having ridden the new streetfighter v4s and mt09 sp, my suspicions were correct. My QS feels clunky/harsh and sluggish. I've tried all variations of shifting and it still happens, even after switching from Kawi oil to Mobil 1. Any tips?

Check chain tension, if it is off it can not feel as good as it should.

How is it in the upper RPM range? Low RPM/light throttle QS is a bit clunky but no issues in the mid to upper range. The shifts are instant. Definitely check the chain slack.

So after 2 chain slack mentions and some research I took a 2nd look at it. The chain slack was within spec (28mm), but I decided to tighten it more (22mm) and it did something. The clunky upshifts are mostly gone. Unfortunately downshifts still have an odd feeling (even above 6K RPMs) but definitely better. Thanks fellas!  :763:

Sorry if it is a silly question, but you are completely closing the throttle before you change down aren't you? Because if you aren't, that could cause the issue.

Yes, sir. I'll just keep playing with chain tension and oil brands. Hopefully the Brock's springs help with clutch feel during stop and go traffic.

Also, worth mentioning that the QS does not require a lot of force. Some YT reviews say it's not "crisp enough" or how one should put it - I think it's just fine and I've never had QS on a bike before. One tip trough - don't go too soft on it, operate the pedal thoroughly... this is not a tuned 1 oz trigger on a rifle, it need clearly defined "kicks".
