2017 GSX-R1000 S2B: Episode 3 - Throttle Blade Derestriction

2017 GSX-R1000 Stock to Brock Episode 3: Brock’s topic of discussion is throttle blade restriction. Here is a detailed video discussion to not only verify the processes to prove ETV restriction exists on the 2017 GSX-R1000, but also demonstrate that a properly flashed ECU can open the blades much sooner and also prevent this power-robbing menace from closing the blades prematurely. Watch horsepower suddenly appear like magic, with no other modifications to clutter the data. The best news? Brock and the crew are just getting started! And this video will give you a glimpse into the type of scientifically-controlled chaos Brock and StupidFast racer, Richard Gadson, are willing to endure to extract every last pony from Suzuki’s latest offering.

[@Da-wooley18]

Brock Davidson hey I convinced my dad to buy the gsxs 1000f last year and I was wondering if that bike would have the same throttle plate issue because to me it seems to have a very odd power surge Also I was wondering if you had anything for that model because it has the 08 gsxr 1k motor in it

[@BrockDavidson]

@Busa1811 wolaver, We don't have any parts for that bike, or any experience with it - sorry.

[@DJSpinj]

Thank you for posting the video, Brock. It is very informative, and with things caught on camera we now have solid evidence along with empirical data to support the reality of the restrictions imposed on these newer bikes. I own a 2009 GSX-R1000. Do you happen to know how much restriction there is on this bike? (e.g., at what point throttle blades close during wide open throttle, ignition timing retardation, etc.) I think the 2009 - 2016 Gixxer liter bikes are the same, so if you have any information you can share on the restrictions on them that would be great.

[@BrockDavidson]

Thanks Spinj. No restrictions beyond the standard exhaust, TRE required, speed limited stuff that has been around for years.

[@DJSpinj]

Wow, that was a very fast response! Thank you Brock! However, I am confused by what you mean when you said no restrictions beyond the standard exhaust. I have spoken to two dyno tuners who own their respective service shops. One told me that the bike's throttle blades are 95% open at the upper rev range, and the other told me 94%. Consistent information this is, but what can you say? I am thinking of flashing my ECU, but I thought I should seek your wisdom as you are very experienced in Suzukis.

[@TheDriversPerspective]

This is the kind of content that I love seeing, great job breaking it down and showing what the stock ECU is doing.

[@JK-qj9qp]

I really admire what you're doing Brock. Your work is awesome!

[@AJTalks]

16:05 I can totally feel that restriction down low in my 17 GSXR 1000R, it doesnt come alive until 7k and dies at about 11k. Very excited about tuning it now. Excellent video man

[@iannsr125]

Alex Johnson how many miles is on your bike and what country you from

[@michaelsmartin5388]

I have to say since watching your videos I am learning something new each video. I have minimized my TV watching and now educate myself on Brock's videos. Not a sport bike rider but I love the mechanics having spent 41 years plus working around steam turbines, gas turbines and generators.

[@BrockDavidson]

That is awesome!

[@Da-wooley18]

Great video Brocks team we all love the step by step build project on this this gsxr 1k and the information that your putting out there for all to see a glimpse into the dyno world I'm sure myself and a lot of us out here take all that tuning for granted and just throw all leg over these bikes and go ride

[@disturbedgsxr]

SICK!!!! Cannot wait to see more impressive already i need a bigger garage!! Thanks again your videos are meticulously done and very informative and to see the power gains step by step is awesome keep up the good work sir!

[@mightymouse6363]

This video is exactly why I buy Brock's exhaust on all my bikes. He willing to share information where other companies are so hush, hush. Although I ride a 16 BMW S1Krr now I owned 4 Gixxer 1k's and I'm glad to see Suzuki is back in the game. I will follow this build til the end

[@poohead4360]

honestly, have to say this is my FAVORITE bike video. wow.... nice work sir.

[@sural89]

amazing job ...it's even more restricted than expected

[@GixxerL]

Hi Brock I'm watching from the uk and want to say thank you for educating me, I feel as if I should be paying you for all this information and am very grateful , I look up to people like you passing your information down to the next generation of humans not knowing a thing about this area like me, lol so thank you again from all the way from the uk 👍🏽

[@BrockDavidson]

@Gixxer 600 L2 - thank you for the kind words...and it's nice to hear that we have at least one fan from the UK.

[@Glen45]

Very clear and informative. I look forward watching this develop.

[@donjuan1933]

Brock totally awesome keep doing what you're doing! I'm learning so much

[@Mark-zk7mv]

Excellent videos! and great explanation of things. very fun to watch. Thanks man, please keep me coming.

[@lghazmat]

great job brock's and excellent teaching too two thumbs up for brock's gsxr-100

[@elijahinky]

awesome stuff Brock! Can't wait to see what she puts down! Exciting stuff!

[@TheAstraios]

Probably the best instructional video on dyno work I've seen. No wonder 650ib's loves you guys :D.

[@BrockDavidson]

Thanks! We like 650Ib also, he's a fun guy.

[@awaywayye]

WOW.....I have just found this channel....amazing....subbed!!!!

[@triedproven9908]

I absoloutely love what you're doing here Brock! You need more likes!!!! Give this man and his organization more likes!!!!

[@brantleysmith6386]

This is the bike I've been waiting for. Can't wait to see what you guys do with it. I would love to have a brocks tuned gsxrR. When I get mine in sending it off to you guys. love the video's. Keep up the good work.

[@Towert7]

I'm very interested to watch the progress of this bike modifying so I'm subscribing. Thanks for making these informative videos!

[@oldschool6268]

Brock way to show your customers what's going on, you are the man ! I just hope it gives BMW a run for the $. I'm waiting on the next busa to share a room with my ZX14R, I love Suzuki products.

[@Gypsyman40]

This was one of the dopest tech videos I have seen in awhile. First time seeing the throttle blades work in real-time. Very nice...

[@BrockDavidson]

@ Gypsyman Racing Thanks it was a ball for us also! Did you notice the secondary injectors joining in horsepower-making fun also (:

[@kennethengstrom583]

Awesome video👍I looking forward to the next one😳

[@rwd323]

Interesting stuff, looking forward to the next video

[@triedproven9908]

This also makes me appreciate the physical connection between throttle and butterfly so much more.

[@NebulaLuna]

I have a 2023 gsxr1000 and this is VERY informative, thank you!

[@BrockDavidson]

Glad it helped

[@bigboyztoyz1960]

So cool ! That fuel spray is "whew" No wonder why litre bikes drinks fuel like there is no tomorrow.

[@jeannoelsandrazie1874]

Well, you've got to feed those 160 horses. 😊

[@corinful]

Awesome video.... thanks Brock! Can't wait to see it with some aftermarket parts on board....This bike is literally gonna fly

[@ultimatefinish6491]

great job... love these gsxr vids

[@user-wx6fs7ls5b]

I will probably never get a newer GSXR but this video was so damn interesting to learn from.

[@Onedown5ups]

love these videos Brock

[@infinitycl]

Nice, can't wait to see what this bike will actually make.

[@SuperbikeDiscovery]

Wow what a great video and what a channel! Thanks!!! Subscribed!

Very cool demonstration!

[@thanhhainguyen5522]

Thanks for your video

[@cowboy_broke]

Very well made video.

[@rx7cblink]

Woowwwww All I can say you are the man, I have recently suspected exactly what you have just confirmed. I have a 2014 BMW HP4, 11 GSXR 750, got rid of my great 05 GSXR1000 (much regret) among my heard (02 GSXR 1000, (2) 06 Ducati sport Classic 1000's and a project 2000 TL1000R), but I too have always been a Suzuki man. You just solidified me getting a new 2017 GSXR 1000 RR The King is back ...

[@therealslimshady4555]

rx7cblink hi why do u regret selling your Suzuki gsxr k6 k6 1000 i would never sell mine.what rwhp had she?

[@Mark-zk7mv]

looking forward to episode 4!!!!

[@jaredmoss7403]

These videos are awesome, makes me want to buy your Products, you actually know what your talking about.

[@LightningMAS]

very nice demonstration!!!!

[@MikeOnBike360]

Great content! Thank you.

[@everydayirace]

Thank you Brock

[@Themanu2222ful]

looking forward to the complete motor pomp up! cheers from holland!

[@javiercarrion6843]

Great Videos Brock for sure I have learned alot. I do have an R1 and I do watch 650is's videos and want the best performance for my r1. I do know about the throttle bodies and have not fixed the flash just yet But that will get done ASAP.

[@pags1981]

Great vid, love messing with this stuff too. Got a power commander and Woolich racing flash on the 15 Zx10r and Yoshi system. Can feel the torque / hard pull now. Not 100% keen on fly by wire.

[@ELEDUCADITO1]

I wanted to thank you thats all for a great company

[@titoinette31]

These are rich lessons. Thx ! :)

[@daveyt4802]

Only the best from BD.

[@therccelebrityspeedfresh5393]

Nice job man looking good bro I miss riding my motorcycle

[@knoogoodzkngd5014]

this is just awesomeness keep it up at the end of the video could you include what to expect on the next video .... Great work

[@BrockDavidson]

@Tyler May - thanks and great tip!

[@gsxrrrider]

Hi brocks what's up I have a question I means your r opening your bike bolts every time If they lose their ring so what can u do

[@ryanh2691]

hi Brock, just bought a gsxr 750. would the same rules apply? is there any damages that could possibly come from this? thanks man!

[@cowsauce9099]

So when is the next vid going up?? I want to see the power before I buy one.

[@fwh79FOXR6]

Do these bikes still need a throttle blade sync? Or is that something the computer does automatically now?

[@Gonzo145]

Is it work the same Way,that they dont open totally on a gsxr 1000 k7 k8

The most informative video I ever seen regarding the process of tuning a bike. Just one question, does the bike runs lean with the secondaries wide open?, if not, is the ecm and oxigen sensor correcting it? When I pull out the secondaries on a Vstrom 1000 I had to enrich a lot the mixture on top. Thanks !!

You already ansewered my question down below. Keep going Brock !

[@turbotyoma]

Brock tell me, please: is it just ETV derestriction or fuel was corrected also? What was AFR in comparison to stock after ETV derestriction? Thank you for GREAT videos and knowledge!

[@BrockDavidson]

Please click show more and use our time stamps to quickly find the areas in our videos that can properly answer your questions.

[@2m173]

Looking forward to seeing this series as it progresses. My question is doesn't flash tune make it possible to tune everything within the ECU the same as you would with a power commander? Wondering why you would have to add on the piggyback ECU controller with the flash tune, or am I thinking about this wrong?

[@BrockDavidson]

@ 2M That's their claim and we plan to demonstrate both. Currently, Flashtune does not offer active tuning for the 2017 GSX-R1000, so we any ECU tuning would be a course guess compared to what we and do with the power commander. Once active tune becomes available, we will use it also, as well as their PCV map import function into the ECU. We have PILES of info. to come!

[@DewaldVDB]

Hi Brock. Wow man, well done on this episode series so far. I share your excitement every step of the way. Do you perhaps know if other 2017 models have similar throttle blade restrictions? Thanks for your honest videos, really appreciated.

[@BrockDavidson]

It's most throttle by wire bikes these days. BMW s1000rr, almost all R1's, almost all ZX-10's, H2's are the ones we are working with.

[@PapaWheelie1]

That is awesome- wish you could improve its looks so easy 👍

[@rudeboy64h]

@Brock do you sell ready flashed ECU I have the Gsxr 1000R with R11 Slip on what makes the best performance tune up I’m in the United Kingdom please help me out I’d like to remove all the restrictions on my bike apart from the top speed limiter

[@tomasa4440]

Got a 2016 GSXS 1000F. Will the mod, work ???.

[@md12318]

I'm late on the scene sorry for my probably repeated question. Would you combine a flash tune with a power commander on a new 1k liter sportbike? Or just one or the other? Thanks!

[@BrockDavidson]

@Mick, please go to our FAQ's for your answer: blog.brocksperformance.com/faq/do-i-need-a-pcv-when-installing-a-brocks-performance-exhaust-system/

[@devil2005iscool]

When you are swapping ECU's like that, do you need to code the keys again to the new ECU or can you disable the immobilizer entirely? Also; is de restricting the STAV actuator something which can be done at home without a new fuel map? or would you need to a new fuel map to cater for the throttle blades opening ealier and staying open from 4000rpm onwards? lastly, what tool do you use to flash the OEM ECU's ?

[@BrockDavidson]

@luke cooper - it depends on the bike. Some we can keep the immobilizer and most we can simply disable it, if required. That depends also, if you mean disable it manually - you can remove the secondary plates. Older bikes might not require much mapping, but almost all newer bikes do. We use MorDefy by Guhl Motors (beta) ftecu, winols and a couple others. Search forums dedicated to your bike to find the one most that owners are most happy about. Please go here for additional info: blog.brocksperformance.com/faq/will-a-brockflash-work-with-my-stock-exhaust-or-with-non-brocks-performance-aftermarket-exhausts/

[@devil2005iscool]

@@BrockDavidson Thank you! you're videos are extremely saturated with knowledge and experience. I wish you the best of luck and ill look at your blog. Thanks!

[@braedancleave2185]

Brock, loving these videos, so interesting seeing how you tune these bikes. I just have one question in regards to restricting (and tuning for more power) - What (if any) effect does this have on all the stock parts such as the pistons, crank shaft, all other internal parts - Would these parts be more likely to break or wear faster after tuning as such ?

[@BrockDavidson]

My take on it is this: we are only removing the restrictions the OEM's are FORCED to put in place. They KNOW what is going to happen to these engines after they leave the factory... we are simply allowing the engines to work as if they were not restricted in the first place. And THAT is the key. Don't get greedy - just remove the restrictions and the bike will live a long and happy life.

[@BrockDavidson]

One other point - the European version does not have the same restrictions at 100% throttle.

[@jeremybly]

Hey Brock I have a 2019 Suzuki GSX-R750 since it's not a 1000 do you know if this bike has throttle blade restrictions or any restrictions?

[@BrockDavidson]

Hello - yes, they do have some restrictions. Get with the guys at FTecu

[@edsonalmeidaracing4848]

That's pretty much impressive....

[@DearMajesty]

Cool!

[@eniamreg54]

I have a 2013 ZX10R, if I send my ECU can you D restrict it? I could see why down low for traction reasons but not up top. Also when you did just that was there any side effects to the air fuel I.E. running lean?

[@BrockDavidson]

Yes, we offer a flash for your 10R. We see huge gains everywhere: blog.brocksperformance.com/kawasaki-zx-10r-11-15-information/

[@renaldolamar]

that's crazy how restricted that motor is but Suzuki says it's the king of the sport bikes hell I still want one though

[@rocket25071]

Brockton can i get the same ECU flash mod on my 06 CBR1000? It has a PC3, should in upgrade to a PC5 as well?

[@BrockDavidson]

@rocket 2507 we don't offer anything for your bike - sorry! Contact our friend Don Guhl at Guhl Motors, he might be able to help you out.

[@hotboytrunningboyzmc5933]

in this video are you running pump fuel or mr12 in the motorcycle the entire time?

[@BrockDavidson]

Pump gas (89 octane Shell) - please see the video description for specifications.

[@TreadTalk247]

Awesome stuff Brock! Love that you love the details as much as I do, data means everything! Love the “Ass Dyno” for sure, but numbers never lie! My ass though, has lied to me before, and the data shocked me! Again, well done Sir…..

[@ianblakemore4681]

Mr Davidson Sir! have you done a vid on performance spark plugs and how they effect the performance of an engine.

[@BrockDavidson]

No. Because no one who has ever spent a fortune on spark plugs to "improve performance" would want to here what I have to say...

[@TheGrandeinter88]

@Brock Davidson does this throttle blade restriction also occur in 2017 GSX R 750 ?

[@BrockDavidson]

We haven't had a 2017 GSX-R 750 on site, so I can't answer your question with 100% certainly. As a general rule, the 600's and 750 have not been restricted in this manner.

[@milwysva381]

Love your videos Mr Brocks! What shift rpm is best for this model? Stock bike :)

[@BrockDavidson]

Sounds like a reasonable, easy question...right? But it depends upon many variables, one of which is that the higher you rev the bike- the more it restricts itself. We remove the restrictions and follow these rules: bit.ly/36aRSEt

[@jim1324]

Is there any change that the throttle blades are speed sensitive ? The front wheel is not spinning. Maybe they only open 100% after 100MPH + in a higher gear ? ect.

[@BrockDavidson]

@James Park No. The ETV mapping is controlled by throttle percentage and engine RPM, per gear and per power mode selection (A-C). For this test, we altered Mode A (gears 0-6) 100% throttle - all RPM's.

I have another, QA at mid low rpm its better to have the secondaries a little close for better torque, did you lose torque at mid low rpm? Seems that this is going to be on par with the mighty s1000 or more!

[@BrockDavidson]

@Sebastian, it is better nowhere (power-wise) by having the blades closed. I have resized a dyno chart to show that it gained @3hp and 3 ft-lbs from 4200RPM - 6500RPM by having them open sooner: www.brocksperformance.com/images/2017_GSX_R1K_LowEndGains2_crp.jpg

[@vxlgsi]

Have you ever checked this on the v4 tuono?

[@BrockDavidson]

No need... They all have it.

[@ericroberts3014]

How does this effect traction control and the ride modes? Although i use neither. And when will this be on market because im very tired of feeling the throttle curve from the factory. I want the throttle to follow my hand

[@BrockDavidson]

@Eric Roberts, they are all separate - and watch our web store and/or contact our customer service reps for product availability.

[@enigmacrk200]

Is it just me or is there no way to view products by bike make model and year on your website?

[@BrockDavidson]

Yes. But please understand that we are a highly specialized company. Use the product search for your make/model - once an item come up, you can use the checkboxes on the left to narrow down mfg. If you don't see any items in your search, we do not have products available for your bike.

[@brandongofast4504]

+Brock Davidson Does this mean the bike will have less engine braking?

[@BrockDavidson]

No. We can adjust engine braking independently in the ECU.

[@gigahertz627]

Mr.Brock is it possible to do a two pipe exhaust system on the GSX-r 1000 2017?

[@BrockDavidson]

Maybe... just not from us.

[@phatrides222000]

so is this the TRE being disabled?

[@codymendoza5698]

do you do flash tuning for 2013 gsxr 1000?....after seeing what the flash did for the new 1000 i want to do it to mine as well :)

[@BrockDavidson]

It's on our 'to do' list :)

[@daveyt4802]

Did you guys figure out why Suzuki would do this? The 186 mph top speed thing? Does the gear position sensor alter the stock HP too?

[@BrockDavidson]

en.wikipedia.org/wiki/List_of_fastest_production_motorcycles#Gentlemen's_agreement_to_end_competition

[@845racingworks]

Hi Brock. Not to question what you do, I love watching the tech videos and find it very interesting, but I just have a question myself. I watched what you did, with the Flashed ECU, telling the blades to stay open, thus giving it a higher HP output, but isn't that change you made going to affect the bike running more rich? Should you not also tune something regarding the air intake and the inlet and exhaust valve openings as well? Seeing that more fuel goes into the system, you need more air to ignite it properly. Can this not cause the bikes engine to have pre-mature ware over the long run? I understand Suzuki has to tune it like that, to meet emission requirements etc. Unless this video you made was just to show us what happens when you just tune the throttle blade positions, and your still tinkering with the air/fuel mixture to be spot on, as well as the correct opening of inlet and exhaust valves. Thanks again for your informative videos, I really enjoy watching them.

[@BrockDavidson]

@EDW 845, thanks!, and good points. Please consider that when we open the inlets, with no additional tuning, the bike gets LEANER at high revs, not richer, as shown in the red line in this dyno chart: www.brocksperformance.com/images/2017_GSX_R1K_LowEndGains2_crp.jpg the rest of your questions will be addressed shortly.

[@845racingworks]

Its strange that it would run leaner, and not richer, but I guess the air flow or o2 sensor picks up that there is more suction or air being displaced through the system, and compensates for that. I will be keeping a close eye out for when your next video appears. I myself, am a Suzuki fan, and switched to S 1000 RR, purely out of frustration due to Suzuki taking to long to develop a bike that can run with the rest of the pack. If this bike does beat the S 1000 RR, I'll consider switching back, but I'm still a bit skeptic, as BMW has set the bar quite high, but hey, I'm open to having my mind blown and proving myself wrong. They have been there before, nothing holding them back, to be on top again.

[@smitfs]

Hey Brock. Francois here from South Africa. Maybe a silly question but what would happen if one just remove the secondary butterfly flaps entirely? or do you still require them at certain RPM to open and close? (side question) - I have a K6 1000, would you advise me to leave them in or remove them? Apologies for all the questions. learning !!ThanksFrancois

[@BrockDavidson]

Throttle by wire bikes only have one butterfly, there are no secondary butterflys.

[@smitfs]

Brock Davidson ah i see! what would you recommend i do on K6 1000 (remove secondary?)

[@BrockDavidson]

You can, but you will need mapping to match the increased air flow.

[@status_zero]

will the changes to the ECU throttle % affect how the other systems function that control the throttle, like launch/wheelie/traction control etc? or are they independent of throttle position?

[@BrockDavidson]

They are independent.

[@status_zero]

thanks for the reply, loving the videos,
