2023 Kawasaki Z H2 CRAZY POWER!!! Exhaust and ECU Flash

#h2 #ecuflash #zh2

This might just be the most powerful and fastest upright motorcycle on the market! The 2023 Kawasaki Z H2 comes from the factory extremely detuned, lacking power and just super restricted. We had the pleasure of getting one of these Z H2 bikes in to see what we could do. After doing a full Brocks exhaust on this Z H2, we saw a little bit of gains, but not enough. We were able to unlock it even more after doing an ECU flash though! This supercharged motorcycle HAS to be the most powerful upright motorcycle on the market. Especially after the exhaust and a little time on the dyno. Remember, these numbers are only from a tune and exhaust. Imagine what these Z H2 numbers would look like if we took it even further? Fingers crossed we get another Kawasaki Z H2 in soon so we can go even further!

Have a motorcycle you'd like to get tuned? Give us a call.

I own one of these, with a brocks penta carbon and a ecu flash, can confirm this bike is absolutely I N S A N E ! ! ! and yes i love it!

Saying my bike has too much horsepower is like saying there is too much money in my checking account 👍

Wonderful diversity in these videos from liquid cooled balanced and blueprinted factory engines to HD pushrod twins. Great videos and highly inspirational. Thanks for posting

Moore Mafia flash, P08 air filter, and exact same Brocks Pentacarbon as the bike in the video. Absolute freaking MONSTER! I've been riding sportbikes since 1992 and have ridden some of the fastest bike made and this was the first bike I've ever ridden that when I'm wide open in 3rd gear and quickshift into 4th at redline and it pulls the front wheel up....all ego aside...I bout pooped my pants. :-)

These bikes are so much fun. My wife has a 2022 ZH2 that we did a custom powder coat job in the frame and supercharger. I put a zx10r header and yoshimura exhaust, sprint air filter and moore mafia remote tuning. Havent tossed it on the dyno but i suspect similar numbers. I put a 19 tooth front sprocket on it and it still power wheeiies in 4th gear with no problems.

I had chris leave the throttle restriction and timing alone for rain and road mode for the wife and give all power in sport for me when i ride it and its so much fun on the track. I have the yager works intercooler on my h2 sx and the boost temps stay super cool when im on the track beating on the bike.

Really enjoy your content and i notice you put a rag around the swing arm when straping it down on the dyno shows you have great respect and pride in your job most techs wouldnt do that
And great the way you show the bike running stock on the dyno then with the exhaust on no tune and then the end results along with the AFR excellence work on your videos

[chitoloveone]

Bro not to sound like a broken record but you
Have the best content anywhere, nobody doing what you doing .
Keep it up brother….

[garyweaver]

that is an awesome video, very well done and much appreciated. wish i could bring my bike to you..

[mwb]

I absolutely love mine it looks so fn good in person when i first saw it i had to have it, just trying to figure out what slip-on i want to put on 700 miles later im loving it more and more

[PBRTUNED]

Killer bro! Yah thats wild for sure. Subscribed!

[Supercharged]

Just have to consider an intercooler when you go above about 220 horse on these. Over 220 the intake temps will get high very quickly under load.

My 2020 model de restricted with sp engineering slip on and sprint air filter made 215whp at 12600rpm
Great roadbike once k-tech rear shock was fitted

I have the Slr Flash and full Akra and P08 sprint and all i can say iiiinsane power !!!! 🤩 Have not dynoed it yet wonder how much power i can expect 😃

[HvyMetalEver]

It would be interesting to see one of these with a titanium system and e85. That e85 would boost power and keep it running a little cooler

[LizardMane]

I have a serious question. If he mentioned this in the video sorry if i, missed it. How does adding an exhaust pipe add more air to the engine?

[mot-trance]

Nice Work !!! But im still confused about AFR and the O2 sensor... I need a clearence about this may be... Im right that in the ECU mapping are also different AFR numbers behind and the ECU can change the AFR about + - 30% with the result from the O2 sensor ??? So if i "just" change my exhaust system to fully open, i do not need any ECU remapping... Please clear me up... Im realy confused right now... Thanks ( BTW.... im on a z900 2019 )

[garyrhode]

How reliable is the engine, keeping it in stock form?

[sural]

what was your boost temp on the baseline pull ? without intercooler those bike are very air temp sensitive

[dg]

Funny how Japanese bikes seem to be far more restricted than European bikes. My mt10 turned into a totally different machine with JUST a flash. Decat/exhaust added a few hp but power gain almost entirely comes from flash, contrary to what many newbs think😂.

It's a damn shame somebody has to pay to fix a bike that's neutered from Kawasaki, in order to get the power that Kawasaki worked hard to engineer and create. Just correcting the throttle-by-wire settings to keep the ECU from crippling WOT at high revs gives a huge gain.
