Brock Davidson there are loads of bike tutorials on TH-cam where the “bike expert” is pretty questionable, I love all of your vids because there is no questioning your knowledge and advise. All your vids are extremely helpful to the everyday garage hero. Thank you for taking the time to make these. Thanks from Boise Idaho!!!
Brock Davidson Ok cool. Your mod works very good and I'm considering it but did not want it to interfere with the tc since I like cornering also. I'm good with not having the slipper function when down shifting. I appreciate how you broke down how the clutch works on this bike. Since it works like a switch, either on or off, I guess that's why the came up with launch control to use with the clutch or maybe it was vice versus.
I really appreciate you taking time out to teach us lay mechanics. Having a physical therapy and nursing background I really enjoy the thorough assessment and breakdown of each topic. I remember about 8 to 10 years ago explaining to people the difference between flashing your ECU versus solely using a power commander / Bazzaz tuner. It was your explanation I heard that made this topic clear for me. I like most people thought this was some type of gimmick or something like the Kawasaki "jumper mod". After I heard you expo it I forwarded people your information so they understand these are not the same modifications. Thanks again
I had to stop when I heard you say lever free play adjustment! You are absolutely correct... you have to have free play in that lever. The way that some videos are telling Harley riders to adjust the lever is wrong. Leaving an eighth of an inch or less play is nonsense. A big thumbs UP!!
@Brock - I see a clutch video series being built here, very nice! Swear I would rather grab a bag of popcorn, put my feet up and watch you do your thing for 45 minutes over any movie, and come away with experience that would normally take me months or years to attain myself.
Hey Brock. I don't even have a bike right now ( use to have Yamaha R6, Kawa ZX6R), but I've enjoyed watching each second of the video. It's nice to see when someone knows what he's doing and doing it well as you are! Thank you!
Another excellent video Brock. Love these longer videos. Lots of details, no rushing along. It also helps you have a nice relaxed way of explaining things.
Have to admit, the difference in launch very was apparent, almost makes me want to drag race. Now if I take that road racing, then off the start line I'll be first to turn one, but afterwards I'd have to back it in on every corner, probably wouldn't get on the podium, but it'd sure be fun.
Great VD Brock ..This is Ghost from the Dubrpanda channel I purchased your clutch mod replacement for 2018 GSXR 1000 and this Mod is a must for drag racing.. especially stock wheel base.... I raced Chris more down in Mexico and was able to out 60 ft him because of the mod... he caught after the 8th but your product is a must. To all he's dead on!
@John Jones - thanks for checking in with your results. We try hard to get it right and its great when riders confirm. Gotta watch Chris...he has some truly #stupidfast stuff!
The Japanese are impressive people. Creative, innovative and they take pride in their work. I had the pleasure of living there for 1.5 years. Their motorsport culture is amazing. Konnichiwa💪
Hi! Why did you choose the hub from k5-8, and not the hub from k1-4, which does not have this slipper clutch initially. It should be lighter and cheaper. Also, the working area of the disks is larger by k1-4. But 5 springs instead of 6.
5 springs dramatically limits the fine tunability of the static spring pressure. Backdating that many generations is also not legal in most racing organizations. Of course, you can do as you like., but pay special attention to the inherent oiling capabilities.
Drag racing with my Z-28 camaro if you don't use the clutch properly you are either going to smoke the tires or bog the engine with open plenum intake .. I had slipping the clutch to keep the tires from smoking or the engine bogging .. I had down to a Science.. Thanks to all the jooow Tooog videos I watch I learned Never let off on the gas.. just hit the rear brake if you start to wheelie too much . With my slow old Yamaha FZ-07 I smoked a Harley at a stop light the first race .. the next red light I tried to do a wheelie .. and I let off the gas the the Harley actually pulled ahead.. but not for long as there was a huge sweeping curve ahead. . anytime the road has curves it's bye bye Harley .. You need a longer swing are for Drag racing .. but I suppose your GSXR is a track bike . I was Pretty good at whole shots on a dirt bike too .. at age 16 I pulled the whole shot on 33 125 motocross bikes in my first moto cross race..
22:30 if the stack height is reduced you don't loose spring pressure ,you just loose preload (so you eventually get some slack between the stack and pressure plate ) With linear coil springs like here (non progressive springs) you can't get more pressure or less pressure by compressing or decompressing them,but only more or less preload. You need to shorten a spring it by cutting it and compensate with a shim to get more pressure, with the same preload (spring dimension) It's just a bar of steel,but in a helicoidal shape. A shorter bar is always less flexible than a longer bar of the same steel.(see leaf springs stacks) Normally the spring kit you sell is composed of springs with a slightly thicker bar diameter,or a different alloy from the stock springs. that's why they create more pressure,once preloaded : same coil length but thicker. Very interesting video,specially the part where you adjust the slack on the thrower.
If the stack is shortened, the pressure plate will move closer to the backing plate (spring pocket in pressure plate moves also - spring post does not), which will make the spring preload (if you prefer) and resulting overall static pressure, less.
Yes. Peoples are often confused by the spring pressure and the preload associated with its use. As a pro being attentioned to the details and parameters like you are, in your videos,you should use preload and pressure in their specific use,moreover speaking about springs and shims used with. Very interesting video,keep it this way,and don't be afraid to be technical,you have the good and patient way to explain principles correctly. Greets from France : )
thats a sizable gain in performance i can tell just by engine sound and how fast it reved up tire must of broke good bite at the amount of power being put to the concrete
Hi from India 🇮🇳 been following your all vids and are helpful as I vl b changing my clutch and my oem service guy says always go for full clutch change.. not just the plates.. thanks man.. great work 👍
It's the OEM service guys job to sell you as much as possible ;) That said, if your clutch is not functioning any longer - a complete change is a good idea.
Brock you’re a great dude man record breaker real closer I say this because I feel like we’ve had a military guy an executive Guy they’ve run the country but we’ve never had a racer run the country and it takes a lot to break records and innovative ways to break records when you run for president my brother I’ll definitely vote for you my whole family we need a razor to run this country appreciate you bro have a great day
@27:30 ish you talked about the inner basket tool... I found one of those tools in the package and didn't know exactly what that was for, but now I do! HAHA Being it was a tool from EBC I knew it had something to do with the clutch at least... Another great video. And nice launch at the end, you still got it.
ya i picked up that bad habit as well impacting clutch hub nut and countershaft nut but dont do it with aluminum axles steering triple tree center pin dont use impact you will pull threads right off your part been there done that thank GOD for ebay if i had to go to dealer id have to take out second morggage on house i just bought a complete transmission with shift forks and drum and all springs and shafts in perfect condition for 90 bucks took back the 2 new gears i just paid 480 bucks for
Is it dumb that last year I picked up a brand new 2020 s1000rr m. And this year I'm picking a brand new, 0mile 2017 gsx r1000r? I really like the looks of the suzuki... After watching this, I'm definitely sending me ecu for a stage 1 non pc and getting the predator series exhaust.
Love the videos Brock very informative. You make it sound at least to me, that slipper clutches are relatively new when they've been in production bikes for well over a decade. Also I get the aspect that a dedicated system is better than a system designed for every aspect of riding but I don't follow when you say a slipper clutch is either on or off. On to me is fully engaged, off is disengaged. There seems to be plenty of 'slip' in between. Other wise you couldn't take of from a standstill. The instant your driving forward I don't understand how a slipper clutch grips less or is harder to modulate than a regular clutch.
Some of our riders prefer 1/2 turn - that's fine, as long as we check the adjustment frequently as 1/2 turn out does not allow for rider mistakes as well as the longer adjustment. This is simply due to plate wear preventing full clamp force if the clearance drops below 1/2 turn....which leads to a completely destroyed clutch on the next run if not caught. Hope that makes sense, lol.
First, thanks for this video. It was supper helpful. I just needed a quick run thro because the service manual made no sense on the adjustment procedure. How often would you recomend checking the clutch pushrod adjustment for street? Also i wish there was a way to retain the slipper and still have those awesome launches with the backdated clutch. I wish i could have both! Its so hard to launch this bike, and keep the wheel down and go forward lol. But i dont wanna give up my slipper!!
I wish I had a brock bike. It would be nice to ride a fast bike knowing that the person who built it knew what they were doing. I was scared to ride my bike after I did an oil change lol.
We have a very fast ZX-14 for sale, as well as a supersport drag ZX-6R that will be available soon also. E-mail: bmail@brocksperformance.com for details.
Brock you're amazing. Question: Now, with your mod installed, does the slipper clutch aspect still work for downshifting at high rpm for circuit racing like originally intended?
Hi! I have a serious question regarding this setup. First of all, great and informative videos, I enjoy them a lot! The question: Me, as a competetive track rider, would I benefit from this setup or would this setup shred the slipper cluth possibilities and make the bike not suiteable for track riding? I can see some benefits why to use this setup but I'm worrying that the already pretty good slipper clutch would lose it's glory if I upgraded to something like this. Hope you will get back with an honest answer. Kind regards, S.A Racing
Very informative ! I don't drag race but I have a question : I bought Heavy Duty Spring set from you for my new Z900RS Café. I was surprised there were only 3 springs when I got them. Looking @ your vid I just realized it is BC I have a slipper clutch ! (my first one) So what is the purpose of installing the stiffer springs on it if it "locks up" on the OEM springs ? On all my previous bikes I always upgraded to heavy duty springs but there was never a slipper clutch in them. So should I install your kit or not on my Z900RS Café ? What would it do/ change ? Thanks, George
You have an "assist" clutch with a slipper. Our kit allows the bike to accelerate quicker, while removing your mushy lever feel, until the assist kicks in and removes any feel you just had from the equation.
Is that the same as a slider, what your talking about (slipper)? Would you say that a full lock up is a better application for drag raceing on a stretched bike? And I love you carbon fiber wheels I'm buying some from you will they work on a jen 1.....
@Anthony Welsh - from a drag perspective, no a slipper and slider are very differnt. The slipper works like a conventional clutch...a slider works like a mini bike centrifugal clutch: no clutch lever required, but the bike in gear and it will accelerate as you twist the gas. Your lock-up question on a stretched bike isn't so easy. You can have anything from a simple 2 stage lock up, to a slider, to a multistage to a Gen 2 multistage. The use of the bike would determin the need. Yes we have many 'Gen 1' fitments, click here for more details: brocksperformance.com/wheels-tires/bst-carbon-fiber-wheels/
@@BrockDavidson I have learned alot just by watching your videos I love the tips you give it opens a whole new bunch of ideas now I see your talking about a factory set up.....I like the world wide bearings topic you did now I have my case apart and I'm doing it to cam bearings and transmission bearings....mabe one day I'll get to see you on the track brother!
OK! now I don't feel so stupid because I took my new to me mostly stock gen1 busa to the track and I couldn't get it under 1.85 60ft and that was on the back wheel. Now the next question. What can I do to keep the front end down after the 1-2 shift? It picks strait up when I spray the 40 shot after the shift.
Hi Brock... nice mod here. By the way, in what comes to performance spark plugs it has Been really hard to find the apropriate ones for this bike, and specially in the case of bmw because they have lifted the compression of the pistons compared to the previous model, what turn things more dificult... brisk claims itself their racing silver plugs with 360 degrees diacharge to be the best ones... although i have already seen 10hp loss on dyno with them... Any right choice dyno prooven for this mod...? Thanks
@Mike, the bike hadn't been fully lowered in this video. By the end of the series (lowered front forks/radial mount strap kit /rear lowered with window link and seat stepped) I could easily touch flat-footed, even on the street with little or no strap. I'm 5'8" with a 30" inseam. Hope this helps - BD
Slip releases on back-torque, but also bites on acceleration. Hard to modulate a slip/assist clutch on bite due to ramping actions. Weren't the first versions just slip (back torque) without assist (forward torque)? Single ramp versus dual?
with cable clutches, the clutch material plays a role where it engages? cus ive adjusted my gsxr properly using the worm gear, cable and adjuster wheel and it releases same spot each time
I noticed you didn't mess with the cable adjustment under the tank like the manual says. Is there a reason why you would or wouldn't need to mess with that adjustment?
Not all slipper clutches are designed like this. This is called a "slip-grip" clutch. The problem here is the "grip" part. I know you're aware of this, but some might hear the term "slip-grip" and this is what is meant by that.
We don't get caught up in marketing babble. In our world, it is a ramp assisted slipper or simply assisted. More info: th-cam.com/video/agTJDXsYIr0/w-d-xo.html
I feel like you’re referring to the assist, the slipper ramps are on the opposing side as the assist ramps. There’s some bikes with a slip without assist
@@BrockDavidson just double checking, and I meant my second half as a question, do you know of any that slip but don’t grip, like only working on downshifting side
Is this the brocks ultra lightweight clutch billet mod? I have that right now it says it’s for drag racing but this is making me question it now I have a 10 inch swing arm extension
@Jason Stewart - This converts the clutch over to a unit that includes our ultra mod: brocksperformance.com/clutch-conversion-kit-for-gsx-r1000-r-17-21/
It helps prevent the plates from sticking together due to capillary action, so oil can flow through properly when the clutch is pulled in, for smoother operation.
Brock, i have a 2016 GSXS-1000. Can i use the 2005 gsxr clutch mod kit? I went to the track tonight and have the stereotypical on/off switch that my Hayabusa used to have before the mod
5spd5thgen - i think so? As amazing as it seems, you are the first to ever ask, lol. Let me look into a few things. Please e-mail me at: bmail@brocksperformance.com and i'll let you know what I find.
@David, glad you like our vids. It's the design of the clutch, stiffer springs actually work better as the limiter locks up quicker/more solid... but it still can't be slipped properly.
How off is your color saturation (or whatever controls color tone) that your Makita mini impact looks green instead of blue? Did they make those in green? That is my favorite tool in my garage but I've never seen anything but blue and black.
@Reese Harvey, please check out this FAQ on that subject: blog.brocksperformance.com/faq/have-you-ever-used-the-oem-launch-control-on-a-modern-sportbike/
Hey Brock, I was wondering if this kind of clutch mod would fix the R1 known off on clutch problem and if you sell the parts for the mod? I have a 2011 R1 with 3500 miles on it.
We did not try launch control on the GSX-R1K. FYI: we have never used an OEM launch control that did anything other than slow us down at the drag strip. It seems to work ok for drag racing rookies, but it is far too intrusive for a skilled rider with a properly set up bike.
Brock, id love to know why i get get feedback in my clutch lever 2021 gsxr 1000r when changing gear? Clutch lever pulled in and when i shift gear i feel a click in lever almost like i can feel gear engaging, u ever cone across this Thanks
That's a function of the assist clutch that I also find particularly annoying. Our clutch conversion kit cures this. brocksperformance.com/clutch-conversion-kit-for-gsx-r1000-r-17-23/
I know you are just demonstrating , but I thought you were supposed to soak those fiber plates in ATF before assembly same as coating the steel plagtes ?
ATF? Maybe in a Harley.. but not in a sportbike with a wet clutch. Mixing ATF and synthetic motor oil can make an engine destroying mix (or lack of mix...) for sure.
So would this set up be ideal for other kinds of Motorsports like track racing as well to get better launches at the start? I’m just curious to if there are any differences in clutch set up drag v track racing having done neither myself.
If you need a smooth/clean launch from a dead stop - yes. If you need the slipper more for the racing you do, then you might not need it. You would need to try it both ways to see which works better for you.
Would this be possible with the 2008 Yam R6? At the moment, it does a mid 1.8 to the 60 with a 10.5 ET. I've seen on your site that you do the 09-14 R1, but would I be able to retrofit the r1 mod to my r6?
My 06 GSXR 750 makes a howling noise when I slip the clutch. Does it on the drag strip or even at red lights with soft launches. What could be causing that?
Okay. I didn't know they put them in back then. Glad to know it's nothing to worry about. It already was coming up with the 17/47(0/+2) setup. I just assumed it was the additional power and stock height vs my Katana which was lowered and strapped down. It's .08 slower than the Kat but 10mph faster in the 1/8 mi. I imagine the 16 front is gonna make it a bitch to launch now. Lol. May try to lower and strap it one weekend and try my luck there.
brock I have question, I just got a zx10r 2018 and I wanted something different as far as an exhaust because I do already have a full system alien head on my 2017 gsxr 1000 , I was going ask you bc I wanted to try something different on this bike and bc you know a lot about exhausts and whats not so im triying to decide whether I want to do a sc project can crt exhaust or the two brothers s1 r exhaust that one rides low and is about the length of the alien head which will perform better in the 9/10 mile , id appreciate your opinion and do you think they'll change the zx10r for 2019 or 2020
I can't tell you about the performance of systems we do not sell/have never tested. I can tell you that overall exhaust length is only one factor which determines power/performance. head pipe lenght/diameter/ step configuration makes the most difference - can length makes close to the least.
hey brock! just installed the clutch mod and i’m having a hard time keeping the adjustment screw with slack after the 3/4 turn. it has slack up until i adjust the clutch from the lever, is that normal or should it still have a little bit of slack

I wish I had a brock bike. It would be nice to ride a fast bike knowing that the person who built it knew what they were doing. I was scared to ride my bike after I did an oil change lol.
We have a very fast ZX-14 for sale, as well as a supersport drag ZX-6R that will be available soon also. E-mail: bmail@brocksperformance.com for details.
Brock Davidson sweet I'll check it out
Brock you're amazing. Question:
Now, with your mod installed, does the slipper clutch aspect still work for downshifting at high rpm for circuit racing like originally intended?
No. The slipper aspect is completely removed... it works like a standard motorcycle clutch.
Hi! I have a serious question regarding this setup. First of all, great and informative videos, I enjoy them a lot!
The question: Me, as a competetive track rider, would I benefit from this setup or would this setup shred the slipper cluth possibilities and make the bike not suiteable for track riding? I can see some benefits why to use this setup but I'm worrying that the already pretty good slipper clutch would lose it's glory if I upgraded to something like this. Hope you will get back with an honest answer.
Kind regards,
S.A Racing
Great question! Generally speaking, a fully functioning slipper would be preferred for track days.
@@BrockDavidson hehe I could figure, thanks for the reply and keep up the good work!
Very informative ! I don't drag race but I have a question : I bought Heavy Duty Spring set from you for my new Z900RS Café. I was surprised there were only 3 springs when I got them. Looking @ your vid I just realized it is BC I have a slipper clutch ! (my first one) So what is the purpose of installing the stiffer springs on it if it "locks up" on the OEM springs ? On all my previous bikes I always upgraded to heavy duty springs but there was never a slipper clutch in them. So should I install your kit or not on my Z900RS Café ? What would it do/ change ? Thanks, George
You have an "assist" clutch with a slipper. Our kit allows the bike to accelerate quicker, while removing your mushy lever feel, until the assist kicks in and removes any feel you just had from the equation.
Is that the same as a slider, what your talking about (slipper)? Would you say that a full lock up is a better application for drag raceing on a stretched bike? And I love you carbon fiber wheels I'm buying some from you will they work on a jen 1.....
@Anthony Welsh - from a drag perspective, no a slipper and slider are very differnt. The slipper works like a conventional clutch...a slider works like a mini bike centrifugal clutch: no clutch lever required, but the bike in gear and it will accelerate as you twist the gas. Your lock-up question on a stretched bike isn't so easy. You can have anything from a simple 2 stage lock up, to a slider, to a multistage to a Gen 2 multistage. The use of the bike would determin the need. Yes we have many 'Gen 1' fitments, click here for more details: brocksperformance.com/wheels-tires/bst-carbon-fiber-wheels/
@@BrockDavidson I have learned alot just by watching your videos I love the tips you give it opens a whole new bunch of ideas now I see your talking about a factory set up.....I like the world wide bearings topic you did now I have my case apart and I'm doing it to cam bearings and transmission bearings....mabe one day I'll get to see you on the track brother!
So I'm not seeing a follow up video on this bike did you guys get it lowered and to the track curious how it did swb.
awesome video! thanks...
OK! now I don't feel so stupid because I took my new to me mostly stock gen1 busa to the track and I couldn't get it under 1.85 60ft and that was on the back wheel. Now the next question. What can I do to keep the front end down after the 1-2 shift? It picks strait up when I spray the 40 shot after the shift.
Once the bike has left the line and the rider is 100% WOT - power delivery/chassis/gearing make the biggest improvements in ET.
Brock is rippin it!!!
Obviously in Mexico 😂😂😂😍
Hi Brock great video. I have the same gen geexr and was wondering what year (older) clutches are compatible with my bike.
That depends on if you have converted away from the assist clutch that comes in the 2017. If so, our conversion lists the replacement clutch required.
Hi Brock... nice mod here.
By the way, in what comes to performance spark plugs it has Been really hard to find the apropriate ones for this bike, and specially in the case of bmw because they have lifted the compression of the pistons compared to the previous model, what turn things more dificult... brisk claims itself their racing silver plugs with 360 degrees diacharge to be the best ones... although i have already seen 10hp loss on dyno with them...
Any right choice dyno prooven for this mod...?
Thanks
We use the stock plugs at the manufactures recommended gap. We shorten the gap to .022 inch if the engine will see nitrous oxide use.
Brock you are a master dragster
I See you on your toes. Were about the same height 5/8 or 9. Tall comfy bike. First super sport I can't be flat footed easily
@Mike, the bike hadn't been fully lowered in this video. By the end of the series (lowered front forks/radial mount strap kit /rear lowered with window link and seat stepped) I could easily touch flat-footed, even on the street with little or no strap. I'm 5'8" with a 30" inseam. Hope this helps - BD
I sure like that 1000, may need to sell the 750 for one..
Al Loring definitely,you’ll be amazed at the difference
you can mod that 750 into a demon ive got one
What all have you did to yours?
ive got just exhaust , but i have friends that have power commander, filter ,sprocket, exhaust
Brock can you show us if that variable intake cam gear set up will swap over to a 10R?
Slip releases on back-torque, but also bites on acceleration. Hard to modulate a slip/assist clutch on bite due to ramping actions. Weren't the first versions just slip (back torque) without assist (forward torque)? Single ramp versus dual?
with cable clutches, the clutch material plays a role where it engages? cus ive adjusted my gsxr properly using the worm gear, cable and adjuster wheel and it releases same spot each time
I noticed you didn't mess with the cable adjustment under the tank like the manual says. Is there a reason why you would or wouldn't need to mess with that adjustment?
Any additional adjustment would only be needed if the two shown cannot reach the desired outcome (due to cable stretch etc...)
What year gsxr did you go back to for your clutch basket?

Not all slipper clutches are designed like this. This is called a "slip-grip" clutch. The problem here is the "grip" part. I know you're aware of this, but some might hear the term "slip-grip" and this is what is meant by that.
We don't get caught up in marketing babble. In our world, it is a ramp assisted slipper or simply assisted. More info: th-cam.com/video/agTJDXsYIr0/w-d-xo.html
That Grom...🤣
I don't think people got the "Ride in Mexico" comment, went right over most their heads
@Getis, lol. I'm surprised also. Maybe we don't have as many @650ib and @doitwithdan viewers as I thought. ;)
Getis Realis I’m one of them I don’t get it ?
I feel like you’re referring to the assist, the slipper ramps are on the opposing side as the assist ramps. There’s some bikes with a slip without assist
I'm speaking about grip and slip. AKA assist.
@@BrockDavidson just double checking, and I meant my second half as a question, do you know of any that slip but don’t grip, like only working on downshifting side
@@davidsherman1389 most all modern sportbikes, before switching to assist, had slippers with traditional spring pressure handling the gripping chores.
@@BrockDavidson gotcha
as always great videos
Nice thank you!
Dat H2 SX in the background
Is this the brocks ultra lightweight clutch billet mod? I have that right now it says it’s for drag racing but this is making me question it now I have a 10 inch swing arm extension
@Jason Stewart - This converts the clutch over to a unit that includes our ultra mod: brocksperformance.com/clutch-conversion-kit-for-gsx-r1000-r-17-21/
Great video! I didn’t understand about rotating that last fiber plate one notch?
There is a special shallow notch in the outer basket to allow the outermost fiber to be rotated one notch from all of the rest.
@@BrockDavidson ok thanks! In the past I don’t think I did that. Does it actually change anything?
It helps prevent the plates from sticking together due to capillary action, so oil can flow through properly when the clutch is pulled in, for smoother operation.
@@BrockDavidson Thanks man I appreciate your knowledge and all your replies!
Brock, i have a 2016 GSXS-1000. Can i use the 2005 gsxr clutch mod kit? I went to the track tonight and have the stereotypical on/off switch that my Hayabusa used to have before the mod
5spd5thgen - i think so? As amazing as it seems, you are the first to ever ask, lol.
Let me look into a few things. Please e-mail me at: bmail@brocksperformance.com and i'll let you know what I find.
Would lighter springs let the clutch slip? Cheaper I guess. Got the cover off, so. Winter and stuck at home watching BP's vids. :)
@David, glad you like our vids. It's the design of the clutch, stiffer springs actually work better as the limiter locks up quicker/more solid... but it still can't be slipped properly.
I have some serious garage envy going on here.
How off is your color saturation (or whatever controls color tone) that your Makita mini impact looks green instead of blue? Did they make those in green? That is my favorite tool in my garage but I've never seen anything but blue and black.
They are a blue-green color.
Brock the GSXR 1000 R has launch control how does that work with the take off at a dead stop?
@Reese Harvey, please check out this FAQ on that subject: blog.brocksperformance.com/faq/have-you-ever-used-the-oem-launch-control-on-a-modern-sportbike/
awesome video
great vid as awlays
I'm a kawi fan...... But what is the better bike? The s1k gsxr or the Gen 5 zx10? For a FBO bike
Finally a gixxer 😍
Hey Brock, I was wondering if this kind of clutch mod would fix the R1 known off on clutch problem and if you sell the parts for the mod? I have a 2011 R1 with 3500 miles on it.
@Will, all you need is this: brocksperformance.com/clutch-mod-r1-09-14/
Great video Brock when will this mod be available to order ?
They are available to pre-order: brocksperformance.com/clutch-conversion-kit-with-ultra-light-billet-clutch-mod-kit-for-gsx-r1000-r-17-18/
Did you try the R model with launch control? Is it just something to put on paper or actually useful?
We did not try launch control on the GSX-R1K. FYI: we have never used an OEM launch control that did anything other than slow us down at the drag strip. It seems to work ok for drag racing rookies, but it is far too intrusive for a skilled rider with a properly set up bike.
Brock, id love to know why i get get feedback in my clutch lever 2021 gsxr 1000r when changing gear? Clutch lever pulled in and when i shift gear i feel a click in lever almost like i can feel gear engaging, u ever cone across this
Thanks
That's a function of the assist clutch that I also find particularly annoying. Our clutch conversion kit cures this. brocksperformance.com/clutch-conversion-kit-for-gsx-r1000-r-17-23/
Brock I have a k3 gsxr 1000 but I put a k7 motor in it does the k7 have a slipper clutch in it
Super Chevy - yes, the K7 has a slipper. We offer a cure: brocksperformance.com/ultra-clutch-mod-kit-gsx-r1000-07-11/
I know you are just demonstrating , but I thought you were supposed to soak those fiber plates in ATF before assembly same as coating the steel plagtes ?
ATF? Maybe in a Harley.. but not in a sportbike with a wet clutch. Mixing ATF and synthetic motor oil can make an engine destroying mix (or lack of mix...) for sure.
simply replacing slipper clutch with conventional basket?am i right?
If you have the correct parts, confirm oiling passages match and provide comparable static spring pressure - yes.
So would this set up be ideal for other kinds of Motorsports like track racing as well to get better launches at the start? I’m just curious to if there are any differences in clutch set up drag v track racing having done neither myself.
If you need a smooth/clean launch from a dead stop - yes. If you need the slipper more for the racing you do, then you might not need it. You would need to try it both ways to see which works better for you.
great teacher's move the world
good explanations
Would this be possible with the 2008 Yam R6? At the moment, it does a mid 1.8 to the 60 with a 10.5 ET. I've seen on your site that you do the 09-14 R1, but would I be able to retrofit the r1 mod to my r6?
Something can be done, I'm sure.
@@BrockDavidson Where there's a will, there's a way ;)
My 06 GSXR 750 makes a howling noise when I slip the clutch. Does it on the drag strip or even at red lights with soft launches. What could be causing that?
That's the slipper clutch. In some bikes it sounds like a dog getting kicked in the ribs, lol.
Okay. I didn't know they put them in back then. Glad to know it's nothing to worry about. It already was coming up with the 17/47(0/+2) setup. I just assumed it was the additional power and stock height vs my Katana which was lowered and strapped down. It's .08 slower than the Kat but 10mph faster in the 1/8 mi. I imagine the 16 front is gonna make it a bitch to launch now. Lol. May try to lower and strap it one weekend and try my luck there.
brock I have question, I just got a zx10r 2018 and I wanted something different as far as an exhaust because I do already have a full system alien head on my 2017 gsxr 1000 , I was going ask you bc I wanted to try something different on this bike and bc you know a lot about exhausts and whats not so im triying to decide whether I want to do a sc project can crt exhaust or the two brothers s1 r exhaust that one rides low and is about the length of the alien head which will perform better in the 9/10 mile , id appreciate your opinion and do you think they'll change the zx10r for 2019 or 2020
I can't tell you about the performance of systems we do not sell/have never tested. I can tell you that overall exhaust length is only one factor which determines power/performance. head pipe lenght/diameter/ step configuration makes the most difference - can length makes close to the least.
Blessings Brock....how do you fix the -c28 code...i hv no valves in...secondary butterflies were ommitted
th-cam.com/video/tn88EtR5O9g/w-d-xo.html
email: bmail@brocksperformance.com and I will try to explain the required adjustment.
hey brock! just installed the clutch mod and i’m having a hard time keeping the adjustment screw with slack after the 3/4 turn. it has slack up until i adjust the clutch from the lever, is that normal or should it still have a little bit of slack
They must be adjusted in order. Max slack at lever, adjust screw at clutch 1full turn out. Readjust slack at lever.
