I’m only 20 minutes in but already feel like an expert on clutches, thank you for taking the time to make this video and explain each part
Same
Whenever I'm in a down mood all I need to too is watch (sometimes re-watch) a Brock tutorial to feel better. Thanks!
thanks Brock, this is the sort of thing that distinguishes aftermarket developers from one another.
I've spent 25 years in the paddock in US and Europe and aee roadrace mechanics just "slap it together". Following the tips from this video will give rookie team mechanic a quick leg up and consistent performance out of the clutch.
Wow! "the guys in the factory know more than we do". I trust humble people and this is the best clutch video every. thank you.
most informative video about Clutches that I've ever seen
Thanks Brock! I just learned more about clutches in 49 minutes than I have in the previous 49 years!
That aerosol cap and masking tape to keep the clutch lever from depressing screams of a lessen already learnt the hard way 😆
Best, most informative video about Clutches that I've ever seen. Great job guys 👍
I can only add that if you see those little high-spots on a steel plate, you will almost always see little grooves around the fiber plate right where the high spot is on the steel plate and conversely, if you see a little groove in a fiber plate. look closely at the steel plate and you'll more than likely see a high spot on the steel that matches where the groove is on the fiber...
Hey thanks for taking the time to explain all of this man. I can't tell you how informative it was from a real world perspective. I appreciate you doing this!
I couldn't believe this video was almost an hour long. I was so into the entire thing that I didn't even notice until you said something. Every detail of the clutch system was discussed. I felt like I was in a tech class for motorcycles. Almost tried to raise my hand. 😂 Many thanks for posting this video. I realized instantly what my problem was and still watched the rest. Enjoyed the educational experience in all of its entirety. Look forward to next class. Thanks again for taking the time.
Brock thanks I enjoyed, I learned a couple things and really liked the video thumbs up. I’ll be looking at the rest of your tech talk videos in the near future.
I really appreciated the patience you put in and detailed information sharing out to all 2 wheeler. I am looking out for more posts, great videos Brock!
Love these videos. I'd watch and listen to them all day! I've had a clutch apart that far but am guilty of just dropping in a whole new stack. Def informative and learned a ton
The Best video I have seen on assembly of clutches.The way you shared your experience and knowledge with such simplicity kept me glued to your presentation. Thank you for sharing your learnings :)
Thanks Brock. Rebuilding my V45 Magna and watching videos like this are really relaxing and interesting. You really pay attention to detail. I appreciate that.
Just reiterating the other comments.. I did learn lots more about bike clutch set-up and maintenance in that one video than so many other vids on here. Keep up the great work. Regards Richard from Australia
Wow, great video man. I now have a much greater understanding of how exactly a motor cycle clutch operates and goes together. I work in auto body and listen to your vidoes all day while im working. Great stuff keep them coming. And a huge Thank You...
Thank you so much Brock for this video, as a owner of a 2016 ZX-14r I'm constantly looking for tech information about my bike. As I love for looking at ways to making things faster and run better...Thanks again for sharing your wealth of experience to help out others who enjoy our sport.
I appreciate you going into depth and explaining how to make the clutch perform and showing the results on the dino. Thanks Brock
Thanks brock for this video as a zx14 owner we definitely are in a class of our own. Us zx14 owners love well informed videos of this bike and wish there were more like yours.
Brock, Thank you Sir. For the very informative clutch maintenance seminar. Lol. I know now way more then I did about my 2016 ZX14R SE.
Clutch. ! And I saved this to go back and listen again and again what you said so it's stamped in my brain. Thank you. So very much. ! God Bless. !
Definitely a long video but it went quickly because I'm learning so much. Really great stuff Brock, thanks for taking us through it!
You are top man.Thank you for showing the tricks and ways to inspect the clutch.I have 4th zzr1400 and absolutely adore this motorcycle and its build equality.
Thanks Brock, you style was perfect for me. The parts of the video needing time to explain were given the time they needed and the same is true of the parts that where simple or repetitive. You had my attention for the entire 50 minutes.
Thanks for the video! T he parts guy could not believe it when I bought half a set of plates, because I was replacing only the worn out parts years ago. Thanks for such an honest informative video.
Thank you Brock for sharing your knowledge. I don't drag race bikes, only road race, and your info is just as useful !
Wow, what a great in-depth explanation! It’s really great that you take the time to share your knowledge. Kudos to you!
You're probably the best bloke in the business Brock . My mate and I ran modified bike 9 second dial in. The 1990,s.. The bandit build you explained was priceless. Thanks for sharing your knowledge..
Another great video from Brock. I have worked on many different bikes over the years and all I can say is, listen and learn from this video. A good clutch makes the bike.
Best motorcycle clutch tech talk on youtube good job brock👍
Mate , I enjoy these tutorials so much , I just scored a ZX14R SE '13 , and I am learning a lot from all your ZX14R series , thanks for taking the time to put it all together for us .
Hey! I did also. How many miles on yours when it went? Mine had 10,000 on mine. Thanks.
Brock you are the man! Real talk, without any BS.
Very informative as always. Keep up the good work!
Hi Brock, just love your wee films. I'm a drag racer but I have learned a hell of a lot about how to make your bike run better and faster. I try to do a lot of my own bike maintenance. Luckily it mostly just the basics stuff oil changes and the like. Your films are very informative and put things in layman's terms. Keep up the fantastic work pal. 😃 😁
Thanks for the amazing video Brock. It was a real big help for me.
I have learned so many things. Thanks for this video.
Wow.... what a great and informative video. I definitely appreciate your content Brock! Thanks!!!
I'm new to the motorcycle world and let me tell you that this video was done right. I learned soo much from it. Thank you.
Today is the end of my 1st year of drag racing. I’ve made a point to take out time to thank those who knowing or unknowingly assisted me. I purchased my alien head 2 full system almost 2 years ago from your website & slowly piece by piece attempted to follow your stock to Brock’s for my 2015 zx-14r. Like most rookies I’ve failed a lot but I kept regrouping. Your video on clutch
maintenance helped me find a problem that has bothered me all year.
Clutch basket had slack it cause a break in my inner basket & broke my shift selector multiple times. I repaired the basket & made progress on my stock motor thanks keep up the good work!
Your Clutch mod & springs gave my bike the ability to hold mph.
@Terrance Sampson - thank you for the kind words. Drag racing is exciting/fun/challenging - but it can also be very frustrating when 'hidden' problems hamper progress. Your appreciation is exactly why we take the time to produce these vids. Good luck, be safe, GO FAST!
,Brock I have tons of respect for you doing these tech videos..
See long description for video time tags and additional information.
Brock Davidson Hi Brock, I have been having a problem with my 2018 GSXR 750’s clutch. It seems to be knocking when trying to get moving from a stand still. It tends to do it once the oil is warmed up. I have checked the sprockets and chain and they seem to check out alright. Here is a video of what happens. ruclips.net/video/vs6GRp31eOM/видео.html I would greatly appreciate it if you can diagnose that as the dealer I bought it from isnt much help. Thanks.
I want to replace my clutch where are you location
Great vedio bro man and a great lesson on clutch and your clutch basket overall..tips that will keep you and your baby runing better for a life times..keep up the good works and blessing to you your team and family
I bought my Busa's billet clutch mod from you and fitted it myself. Bike has been perfect.
After watching this, I think I could have done better on the springs. Great insights, thanks.
Had to comment! This was so easy to understand and very informative 👏 You the Man! 💚 Great video Thank you so much!!!
Wow. That was awesome! More clutch info than I bargained for and totally glad I watched the whole video.
That is one of the best moto tech videos I have ever viewed. Class dismissed!
Thanks so much for this detailed tutorial. Learned so much. Love it!
30 minutes in about clutch stack height was guru moment.. 😮
Must be nice to have Brock as your buddy. A wealth of experience and knowledge. He's from Ohio 👍. Big what's up from Cleveland
I'm new to bikes and for someone with next to no experience this was very well explained !! Thank you !
Best vids on yt. Thx brock for taking time out your day to inform us
Nicely done I wouldn’t worry about the video length you have built a fan base that should by now understand that your trying to put valuable information out there for us to see and understand excellent video keep them up
See you in the staging lanes
Great video. Finally got around to watching the whole thing on this cold winter day.
I don't even have a street bike or anything kind of bike anymore, but I watched your full video and I feel that I know a lot more now than I knew years ago when I did have a banshee that I thought that I know how to replace the clutch, Good job brotha
Knew how to replace the clutch
Very informative and helpful for us who like to DIY!! Keep the tech talks coming!
Great Video Brock! Great detailed information ! Love your videos!
Thanks for sharing the (racing type) info with us, at home about the ZX-14R clutch!!
(You are a gentleman, and a scholar!!)
Exceleent video, the best I've seen on clutch operation, morre of this type of content please
The best clutch instructional video I've seen - many thanks Brock - pity you're in the US and I'm in the UK - take care and ride safe
@Tony Tucker - Glad you like our vid!! Btw, world location just doesn't matter as much these days. More Info: bit.ly/3aXtFTK
Getting ready to do my gen 5 vfr800 ive done prob dozen other bikes so id say I know enough to do but love how ya broke all down and explained lots thank you
I watched this hoping to know how clutch works, I didn’t figure it at all, but understood bad clutch implications and this is maintenance explanation. I like a lot your style!
Great presentation very informative.As a re recent zx14 purchaser, much appreciated.Didn't know you hitting sevens so far back.Totally cool!!
Just ran across this. Good video! Thanks Brock.
You are an amazing mechanic. Thanks for sharing your knowledge
Brock you are Great, very useful and helpful info. THANK U
Thanks Brock! Long videos like this are fine by me.
Awesome video! Technical representation better than anything else on RUclips. Thank You! (Brock must be an ME!)
Just a guy who paid attention in elementary school 😉
Many thanks for the detailed explanation Brock, put across in such a friendly, non-patronising way. I own a 2012 ZZR1400, and this has helped me understand my bike a whole lot better.
We all started out knowing little or nothing about every aspect of motorcycling.. but we learn because we love it. I used to hate when people acted like I was a dumbass for asking a question and have tried my best to be respectful to all knowledge levels.
That's what comes across so well in your videos. A good teacher never assumes anything.
@@BrockDavidson There are no dumb questions. Thank you - I have something that needs just this fix! I broke things and fixed a lot of junk. Drove and rode at speeds that - well - my Mother-inlaw was in the pass seat. And as I topped it out, she yells, "Holy F". Honest - I was smiling like all get out!
Thank you
Olhh
Awesome video as per usual. Cheers Brock
Awesome and very informative video i learned alot of new things beyong just stack height thanks for the videos!
That was a top tier video. Thanks.
It is surprising how similar the clutch is to a automatic transmission setup, I expected it to be something different.
I enjoyed watching your thorough inspection techniques. That is probably the most important aspect of being a competent dyi builder/racer. It is an art to be able to see and understand the clues of what is happening inside the machine.. it will tell you what is wrong if you can spot the signs.
Many thanks for the demo!
This is why Brock is the best, I've been building bikes and cars to race for nearly 20 years and I still learn vital tips and tricks from watching Brock's videos. The fact its all provided free of charge is brilliant but it's also an insight into why the Brocks Performance products are so damn good and deliver the winning results on the track and street.
@martin hodgson - thank you for the kind words. I have intended to do a video like this for years, but it wasn't in the budget. We allocated more funds for RUclips in 2018, and positive comments like these will help us to continue... well, comments and product purchases from www.BrocksPerformance.com
@Brock Davidson I have a question I have a 2018 gsxr1000 base model and when I put the bike in gear and hold the clutch in the bike moves forward and when I am rideing it it is hard to shift gears and when at stop can't get the bike in natural when I change the oil it was some what gunky on the oil plug grays color the bike has 11k miles on it still same oem clutch sorry for any inconvenience and all the questions anything would help

Great video Brock, keep them coming 👍
super cool video keep them coming
Really enjoy watching and listening to your vlogs Brock. It's just interesting to learn about stuff. 👏
Glad you like them!
Very helpful as usual thanks Brock
Thanks Brock . Very good informative video 👍
As always very informative,, but the best part is the " Friends Anti Fiddler FIX "
I don't drag race, but I'm putting a new clutch in my klr650! And found this video helpful!
Man... what a very nice video!!! I really enjoyed it. Thanks!!
Glad you enjoyed it!
very informative! I have an old zrx1200. Thank you Brock!
Save the new clutch as long as possible. The word is going around that it is no problem to let your clutch hang between engaged and disengaged... the clutch was never meant to be between these positions. In fact, it is made to transfer energy from the engine to the drive wheel smoothly and that puts enough wear and tear on it without deliberately dragging the clutch... which is called burning the clutch. If you know of a long light that you have going to work it is best to shift to neutral and sit which puts no wear on the clutch. I have noticed that MSF and the Police Rodeo are advocating to drag your clutch (burn) to get a slower movement... this will tare up clutch plates. When the clutch goes out in the mountains it will not be a fun ride.
Thanks a mil. Understand it clearly now. Thanks for your time. God Bless.
Increasing spring pressure by changing configuration was a real eye opener, very cool. Need to remember that.
This guy is a bike guru!!! Thanks!
Thanks for the vids!
More than I ever didn't know. Thank you, amazing detailed information.
Glad it was helpful!
Thanks for the very detailed explanation I enjoyed and learned some important tips Thanks
Very knowledgeable! Just finished watching your video from my first comment great video! Great explanation! Great Teacher!
Awesome! Thank you!
Thanks Your a great guy. Thanks for your honesty.
I absolutely love these informative videos. I'm a maintenance tech by trade. I know mechanical systems. I really appreciate these. Couldn't learn from a better person.
I would usually replace my whole clutch with the kit provided. This next time around I'm going to stretch this clutch kit out by replacing only what's bad. I really never gave it a second thought about scrutinizing each plate and fiber.
Thanks for watching!
What an awesome instructor. Thanks for the attention to details.
Thanks for watching!
What an awesome video. Thx Brock.
Thanks for the video am not a racer but I've learnt so much about clutches I love bikes so thanks.
Hi, nice more high quality pro info, never knew there was so much to clutches, thanks Brock .

I know nothing about clutches..im just a street rider....but i would really like to go grab a beer with you brother and keep the clutch convo going!! Great vid.
