Thank you for this beautiful lecture. loved it!
Great content! Very informative, I just picked up a z900abs and now I can't wait to drop that heavy stock exhaust!
Go with akra full exhaust. You won’t regret it. Loose over 14 lbs over stock.
Very educational and packed with great useful information.
Glad you enjoyed it
Thank you Brock for taking the time to explain this. It was very interesting & exciting, to learning how tuning works.
Glad you enjoyed it!
Wow! Super cool vid with a ton of info and real world experience. Wish I lived in the US for expertise like Brock that is clearly drive by passion.

Brock you are truly one of the best tuners out there honest and you don't play game's with your business telling costumers what's going on I have a lot of friends in the business and they are too busy for 10 minutes of there time to explain what's taking so much time for products in delivery...and I've seen a true slow down in business because of that lazy Not truly keeping up with customers concern's.....so please stay true too what you love.... Brock's performance is truly one of a kind........and this is Not a paid review this is the God's honest truth.........
WOW! Thank you for the kind words. From the very beginning our roots were based on honesty and treating everyone as fairly and respectfully as possible. We aren't perfect, but that doesn't mean we don't try. Thanks again for the kind words, I will pass this on to out team. Sincerely, Brock.
As always thanks for the info. Velocity stacks don't make power They move Power - Brock. Soooooo informative.
😉
Got a set of your clutch springs sitting on my kitchen table for my Z900 rs cafe as we speak. Unfortunately my Streetmeg exhaust is probably in a pile just like the ones you showed. Worth the wait. And the weight.
Been waiting for this video for ages, thank you Brock!!!!!
Hope you enjoyed it!
This video is epic. Amazing stuff from the master
Thanks for so much information. I appreciate that!
I know I feel bad I kept checking on the eta for my full penta carbon on the zh2 now I've been to busy to put it even on. Love the look of it maybe I'll get time soon to actually put it on.
Great tutorial, subscribed and liked
The Z900 has 36mm throttle bodies. Most other 4 cyl. liter bikes have at least 44's. Almost 130 hp and mid 70's torque is impressive. My '22 gets around 45-49 mpg. I love this bike.
Thanks Brock for deeper insight into this process. My Z900 has the K&N filter, Akrapovic stainless pipes, SC Project slip on, Dynojet PC V & Autotune, and your HD clutch springs. Same end product, more powerful, smoother, lighter, better sounding. Don't have a dyno so absolute numbers is anybody's guess. I think I burnt my Autotune (I'm not the best electrician) so got some fixing to do plus adjusting the A/F ratio in time.
How much $$$ do you think all of that cost?

happy to understand new things from you brock thanks
A lot of useful information, thank you so much for sharing!
Hey Brock! Awesome video with a ton of information. I was wondering, like with other ecu flashes in the mail, is there power left on the table that I would pick up by taking my bike to a dyno?
There can be. It depends on the exact bike and level of tuning expertise of the dyno operator. This might shed some light: blog.brocksperformance.com/faq/do-i-need-a-pcv-when-installing-a-brocks-performance-exhaust-system/
@@BrockDavidson Thanks for getting back. Good to know. I guess also if I'm not looking to shave seconds on lap time on a z900, a little bit of power left won't matter too much at the end of the day. Thanks for the reading material as well, helped clear it up.
Love all the videos, keep em coming 👍
This video is priceless. Thanks so much for dropping this knowledge
Glad it was helpful!
Thanks for sharing.
You bet
I’ve been looking in to exhausts/filters/tunes for the last couple months but every execution seemed so fragmented. This is exactly what I’ve been looking for! I’ve got a stock ‘23 Z900 itchin for some upgrades. Do you have any dealers in Ohio, or should I go through you directly?
On an unrelated note, thanks for all the great content you’ve put out, I’ve been binge watching Brock’s for the last few days. 😆
Thanks for the kind words. Use our dealer locator to find a dealer near youblog.brocksperformance.com/dealer-locator/ or, we also sell direct and ship worldwide.

Another great vid. Your in depth breakdown makes for a great learning tool. Dude will be happy with that setup for sure. Interested in your thoughts on the new Busa as well.
Thanks for the kind words. We have a new Busa on order...but no solid delivery date.
Finally, a video on the z900! Awesome vid! I wished I waited a bit longer before getting an exhaust for my z900. Would it be okay to have your ecu tune with a different exhaust system?
this should help you: blog.brocksperformance.com/faq/will-a-brockflash-work-with-my-stock-exhaust-or-with-non-brocks-performance-aftermarket-exhausts/
Perfect videos!!!
Glad you think so!
you have to do the same on triumph 765 street triple rs 2020+ to see the results!!!
PLEASE do the modern triumph triples! PLEASE! I know it's a LOT of work for you to do new bikes, and you need a different set of softwares for the keihin ECUs but please please 🙏 🙏
Awesome as usual! Brock sorry for off topic question, but do you know why Yamaha FZ1 have same ignition maps at 1 and 4, 2and 5, 3 and 6 gears? It could be more logical if they had lower and higher gear ignition map restrictions, like suzuki..
Please remember that you are viewing info. from a 3rd party hacker software... so take what you see with a grain of salt. We have 4 different 3rd party softwares, so that we can confirm items of this nature. That said, OEM's do things differently. I have no experience with the FZ1, but perhaps they are matching the gear mesh?

Hey Brock! I've now come back to this video 3-4 times just to reprocess and dive deeper on your expertise in order to get the most out of my own 2021 z900 :) Thanks for such an awesome exhaust, and spending your time detailing your thoughts and process. I'd like to pose a question you may find interesting. Do you think the z900 would benefit from an airbox mod? Perhaps a larger intake opening, more holes? I know the sprint filter didn't get as much gain as it does on super sports- but would a mod like some have suggested (Ivan's Performance) for the z900rs, which involved drilling 8 7/8th inch holes on parts of the airbox, would let the engine take in more air? The z900rs seems to get a solid 5 hp just from this. Would do z900 gain some as well? I'd love to hear your thoughts.
@Balaji Rajan - it's possible you would see gains, but not necessarily by "increasing flow". The amount of air introduced into your inlets is simple math.... meaning, is there enough area (in sq.inches) in your airbox opening(s) to feed the area of your inlet(s) AKA: worst case 1 inlet, as engines breath one cylinder at a time, to best case, the combined area of all 4 inlets. In most cases, there is ample area to fill the cylinders on modern sportbikes and ram air helps makes smaller inlets act like they have more area. The problem with some bikes is that the inlets are positioned directly above the engine (due mainly to cut cost by removing ram air and it's associated components--or simply for aesthetics.) which forces them to inhale hot air off of the top of the engine. Please Note: For every 10 degree's F your inlet temp rises, there is a 2%-3% reduction in power. This means that if the new additional holes still allow the air filter to do it's job, it's possible to force cooler fresher air into the inlets as a result of the positioning of the holes. Before ram air, some crafty tuners would run ducts from the front of the bike back to the airbox inlets. Hope this helps - BD
@@BrockDavidson Wow! Thanks a lot for the detailed response Brock! I find myself again furthering my naive understanding - this was very helpful.
Thank you !! So excited to see
A fresh cup of coffee and a new Brocks video, class has begun....
I don't know what your saying but it sounds cool. Lol waiting on my z900 currently
Awesome video, thank you!
Well, you just heard it straight from “THE MAN”.
Good video
always a pleasure to watch your videos Brock. and finally Z900! noice noice. So what is the exact rev limiter now? Is it safe? my tuner refused to increase it....
We gave it another 500 RPM. Remember, you don't HAVE to run the bike to the limiter on every shift...it's nice to have when needed.
@@BrockDavidson completely agree and i never do. But i guess its upon every tuner how they do the job, they cant be responsible for every rider.
But, you that feeling, when the more z900's tune videos i see on utube, everywhere rev limiter being increased, the more you wish your bike would also )))
So if you put a full exhaust on a z900 without a tune and without an air filter, the engine makes 126bhp.. am i correct?
Talking is knowledge and information.....You have something to teach us we will listen!!! THANKS!!! Stay safe!!
Thanks 👍
Wish you would make full system for the gen 3 KTM 1290 SDR,can you even get into ECU? With Euro 5 restrictions, am sure there's power to be available.
Not sure about gen-3, but the folks over at BrenTuning have done so with the 1290. brentuningmoto.com/product/ktm-1290-ecu-tuning/
128 hp and about 74 ft-lb. Very noyce! The engine was sublimely smooth from factory as it was, I'm betting that only got more balanced and smoothed. In the old days, it really helped the inline-4 engines to vacuum balance carburetors according to the need of each cylinder. What sort of balancing exists these days between throttle bodies? Is there a long or short answer?
Short - none. They are perfect and remain that way unless tampered with. We do use this and it helps keep everything clean, so tampering is not considered: brocksperformance.com/wynns-power-charge-fuel-system-treatment/
@@BrockDavidson Excellent. Thank you.
@@BrockDavidson Brock, just going back over this video as a recent interest of mine in the Z900. Is there an option for a more quiet muffler option on your header system? Larger muffler with more sound packing in it, without any appreciable loss of flow? Thanks ahead of time.
We have noise inserts available. Unfortunately, our quiet muffler options in the past simply would not sell...so the inserts quickly give the best of both worlds.
@@BrockDavidson Thanks for the reply. In my experience, the insert baffles typically change the tone too much for my liking, at least in most brands I've heard sampled. I understand the need to produce what the demand is.
I think you're correct about the headerpipe diameters being typically too small to allow the engine to make power like it was designed.
Gday mate, would it be good to remove the vacuum secondaries and put in the shorter stacks? Thanks for all your videos.
On which bike?
@@BrockDavidson z900 thanks
Another fantastic video. Thanks, Mr. Davidson and team!

Glad you enjoyed it!
Could you point me to where I can learn more about more power from 89 vs 93 octane please?
blog.brocksperformance.com/throttle-nation-magazine-the-gas-factor-fuel-options-for-max-hp/
Thanks for this video, I’m interested in an ECU flash for my 2023 Kawasaki Z900 ABS but have come across some news that states the EPA requires all bikes newer than 2020 are to self monitor their ECU and if the it detects any modifications from the factory settings you get a warning light on the gauges and will cause the engine to run rough or not at all, thereby making it impossible to flash the ECU of 2021 bikes or newer, is this true?
Get with BT Moto
Just picked up a 2023 Z900 back in March for my birthday. Ive been running 93 octane in it. Would it be better for the bike to run 89 even though it calls for 90?? You said in the video that 9 bikes out of 10 will make more power on 89 than 93. So if that is the case, I should be running 89? Save me money too lol! Coming from a turbo car tinker where the higher the octane the better to prevent knock hahaha! Thanks again for the knowledge and video!!!!
Correct - 89 makes more power and costs less. Your Z900 is low compression - they say 90 to cover their ass. In the real world, it has to be able to run on the lowest quality 87 and not eat itself up in the process. Here is more info: blog.brocksperformance.com/faq/how-does-octane-affect-my-bikes-power-and-performance/ make sure you read The Gas Factor by Don Smith ---GREAT work by the author.
So we can have this type of power by getting y’all’s ECU flash and no dyno? Giving with all the other supporting mods as well.
That's our mission here at Brock's. If you use our exact communication, we expect you to receive our exact performance.
If been waiting for this!
Any tuners in the norcal area? I have a z1000 2016 and want to install my headers / exhaust but I’m still not sure how or the best way to install and keep the engine like off without having to get it tuned or buy that tuner thing to bypass it
Go to power commander.com and look for an authorized @dynojet tuning center near you. (Fyi...it might be out of state)
Wow Brock what a great informational video. I’m gonna ask once again I got a z900rs and I’d love to have a steering stabilizer built by brocks since basically no one makes one. Thanks I’m local if you need a bike to design one with.
@Cory, go here and request it: blog.brocksperformance.com/product-request/ the more requests we receive, the harder we look at producing an item.
If the bike add an other cam will it remove that 2-3 k rpm range peak of 127 ish horse power? To increase it by continuing the power curb up?
@Wrench N Twist - We haven't messed with cam selection on this bike, but I'm sure there are serious gains to be had as most cam profiles are doctored these days to help reduce emissions.
On my z1000 gained almost 3mph in 1/4 mile when going from a fresh K&n to sprint. Tested same day before and after. Consistent 2 mph gain.
@Jeff Brown, great info! Would you mind placing a product review on our site listing your gains?
@@BrockDavidson done!
Iv never owned a sport bike . So why did this catch my attention ? Lol I don’t know either but it did !
I need a quieter muffler. Is there a bigger one that will fit in your mid pipe?
Please contact customer support for options.
I am from India and throttle bodies of my Z900 gets dirty very quickly. How often should i get it cleaned? I mean the time interval?
Sounds like you need to address why the throttle bodies are getting dirty enough to need cleaning. I would assume this is due to gum/varnish etc? We use this: bit.ly/2Sq1ntt perhaps you can source some in India?
I got my 2022 z900 delivered about a week and a half ago, i've been trying to decide whether to go piggyback system or ecu flash, my only issue is that im going with a SC Project header kit and it doesnt look like many tuners have set up for that kit yet, do you ever do ecu flashes for other header options?
We don't. Try Chris Moore.
@@BrockDavidson will do
1.28 inner diameter sounds like plenty for street. I do want to save that weight badly though.
Here in Florida I can get 90 octane ethanol free or 93 octane with ethanol. Which is better for my z900 do you think? It's bone stock at the moment
Make sure to read the Gas Factor by Don Smith: bit.ly/3g0UHMe
At the 21:39 mark did the bike fall out of 6th and go back to 5th? I hear its common. Is there a fix?
It did..but I belive it was because I accidentally stepped down on the lever. It had never done it before and has not since.
Dang! Getting a 2nd hand z900 and installing these pipes, filter and tune and making it faster than a striple 765rs for less money seems like a very tempting idea now😈
The handling of a Z900 is nowhere near as nice as the Triumph options. Granted my Triumph is a 675R, but to do it again, I regret buying the Z900 over the S3RS back in ‘17.
@@patrickwassall116 i am on a drag race tuners channel talking about straight line speed. Read the room man!!
may b now that the ducati streetfighter v2 is coming, u might want that over the striple 765rs if sharper rakier handling is ur thing
Hello sir... Where i can find the accessory line connetor in my z900. I want to install auxilliary light. Please help sir. Tnx
Where can i tap the wire?
We typically tap into the tail light for switched 12v. But you might want to go directly from the battery (through a fuse and a switch) if you want the lights to work without the bikes key turned.
Does a bike need to be re-dyno tuned after reducing weight to a bike via exhaust, wheels, etc??
No. Remapping needs to happen if significant modifications happen to the intake or exhaust.
@@BrockDavidson so changing to a full aftermarket exhaust from stock wouldn't apply?
That would be considered a significant exhaust mod that would require a remap for proper drivability and performance.
Does this combination still apply for a 2020 Z900?
Yes
Will a k&n or high flow filter damage the engine over time in the name of horsepower. Other words will decreased filtration be a problem in a city or street environment maybe even the drag strip.
We don't use K&N filters. We use the Sprint Filter P08 for sustained street use as this filter has been approved by Ducati for street use and is OEM in several applications.
@@BrockDavidson wow okay
Hell yeah.
Did you raise the redline on this? Or these bikes, If so to what?
Yes. It depends on the bike. This one +500 rpm.
And i sold mine this month! Fuck 😂
Hey Brock!! Is the 2022 Exhaust's plug and play to the 2023 bikes??
@Zach Hostettler - According to our sources, yes. Mechanically the 22 and 23 are the same. That said, we have not yet confirmed 23 fitment.

This is why I could never do an electric bike. This noise is so wonderful.
I feel ya, but that silent 100% instant power is life changing, you become one with your surroundings. A long country or mountain ride on a fast bike that makes no sound is special. Easy fix= have an electric and a gas bike in your garage so when ever you want to terrorize the neighborhood, or hear the birds chirp you can.

Doesn't the stock Z900 2017-2019 have 123HP?
Not on our dyno...
AF ratio still looks safe with full exhaust and no fueling changes.
Yes. These bikes are pig rich from the factory at high revs.
Like going back to the 90's with a stock system that is so restrictive from the factory, what a transformation .
What about e85?
What about a 40 mile cruising range? E85 is for cars. We get more power and an extended cruising range from oxygenated pump gas.
Have you guys been having trouble getting OEM parts from Kawi, Yamaha and Honda? My repair guy has been waiting for 9 months for parts, for my buddy's kawi.

@@BrockDavidson alright just curious. Thanks for the quick reply. Keep on doing the awesome work we all love to see!
I noticed oem prices are really increasing lately. Inflation is bad.
It's the new norm for now. It took my local Kawi dealer about 45 days to get in new clutch parts for my Z900. Guess the boat took the long way around.

Can U tell me what will happen when the bike is going along the highway from 0 to 150 mph with air being forced thru the air intake system compared to the bike sitting still on a dyno machine ? Won't all the settings and data be different with colder air and more being forced thru the bikes system ? Will U need to remap or retune everything again ? Love to know results differences on road vs on a dyno for actual gains or performances ??? Pls !!! Also in my country the same Z900 2019 model I have had to run on our 98 octane petrol. We have better gas in Australia. Would our gains be bigger with higher RON fuel at 98 ?

Dam Brock it sounds savage 🤤🤤🤤
how was the air fuel ratio with the full system and everything else stock? does it run lean?
i have a full akra on mine and wonder if i need a tune.....
It runs very lean in the cruising areas. The bike is much smoother at all revs with a flash and proper tune.
@@BrockDavidson
do you remember how much horsepower does it make with only a full system?
@@sural89 th-cam.com/video/TRICMNOk4aA/w-d-xo.html
This thing is going to ruin a stock Z1000 in a race. They also launch very well.
Hey Brock. Are you ready when the EPA comes knocking?
Watch out brother.
We belive so? Currently, we refuse to ship our race-only exhausts to California at all and we are adding 16 more states to that list soon.
9/10 bikes make more power off 89 octane gas vs 93? How? Why do manufactures reccomend 93 octane then?
To cover their asses. More octane = more insurance against engine failure if you come across a batch of bad gas or run your bike WOT for an hour...neither happen in the real world and they don't care if it costs you more $ at the pump to help them prevent a warranty repair.
