Yamaha R1 Clutch Inspection
Vložit
- čas přidán 10. 01. 2021
- Customer complained of a rattle/grinding noise when the bike is in neutral and the clutch is released. I inspected each item within the clutch and found the clutch to be operationally sound. The damper springs were rattling within their shell. This happens as they shrink over time. No negative impact to reliability or performance. Found burnt steel and friction plates along the way. Due to that and the bike seeing harsher forces and temperatures due to track riding, I will replace the friction, and steels plates as well as add stiffer springs to avoid future clutch slipping.

Thank you! I wasn't aware that the discoloration and burning changed the actual property of the clutch. Mine was still in spec as far as measurements go so I was pretty stumped. After watching this and going back like half of my clutch plates could have joined the blue man group it looked so discolored, but not watching this video I wouldn't have known it was that catastrophic. Thanks a bunch!
You ability to explain and your overall communication skills are excellent.
What a great video. I know a fat bit and still learned a couple things.
Thanks for the upload!!
Outstanding sir. Thank you
Very informational thanks.
Yeah buddy!
I have the same rattle in my 12 R1 Dragbike , I had some grabby clutch behavior, noticed the basket was chewed up so I replaced it, which fixed the rattle and the grabby clutch. although after many passes the rattle has come back, I think its common, its not bad just alarming if you don't know what it is.
There is a lot of great information in your video. I enjoyed watching it. I get a rattling sound when I let the clutch out in neutral, then it goes away when I pull the clutch back in. Should I also suspect the clutch basket? The bike runs just fine otherwise
I have an 07 when i got it it was not starting and the clutch lever was so lose , got it running and the reason wasn't running was the stator magnets blew off so it wasn't cranking and had all sort of error codes they all disappeared with the new stator :) now when i opened the clutch i found the boss was cracked and pieces came off , fortunately they were all still inside the boss so that part was great I haven't replaced the boss yet but i fixed it by replacing the rivets with some SS nuts and bolts + washers over the cracked rivet holes, loctite them in place that's probably gonna workout for a while until i get more work done on the bike .. now my issue is after installing the oem clutch kit the clutch won't disengage and the lever is extremely hard to pull as if the plate stack is too thick ,the kit comes with a few different thickness pressure plates, initially I had 1 2.3 mm installed , went down to the stock 2.0mm and it's still not moving at all last option is the 1.6mm that comes with the kit now i'm thinking it might not the plates but some other issue do you think that ring spring plus ring on the boss that goes before the first pressure plate (with the grove) could be the culprit if they aren't perfectly straight, there is a very very slight deformation barely visible , would remove those two rings damage the clutch ?
I am thinking they wouldn't affect the thickness of the stack since they sit under/inside the first friction plate (thinner one) but i could be wrong .. any clues ? the clutch basket is in good shape and seems to be installed correctly , torqued etc
How many miles do you usually see people get on R1 clutches? Or even just sport bikes in general?
Nice video!
I have a question, if you can reply me it would be awesome!
Can a clutch basket creates vibrations at any RPMs?
I hear some sounds from clutch, light sounds... But my bike vibrates alot, in handlebars, seat, footpegs...
I changed the oil, plugs, chain and sprokets, i checked the tires!
The vibrations goes away while i'm pulling the clutch at any speed...
If the clutch cause vibrations, can you explain me, why?
Are the springs behind the clutch?
Thanks!
I’m replacing my clutch boss (because it cracked). Now some of my steel clutch plates are dark but the hole plate is the same kind of dark (no spots or blue colour). Is that oke or should it always be a light steel colour? Thnx!
Hola mui interesante pero si la campana está marcada por dentro y los muelles tienen juego eso hay que arreglar no?
Hi ,thank you for great video ,very well explained. I have a 03 R1 with same rattle noise ,but only on cold start ,once bike is warm noise is gone. Noise also less when clutch is pulled in. Could this be due to those damper sprngs aswell, or is it likely something else. I have not taken clutch out yet to investigate. Your thoughts will be appreciated.
I would focus on isolating where the rattle is coming from before linking the rattling noise to the clutch. Rattle on warm up could be timing chain.
@@EugeneAlston Thank you for your reply ,I will look into it further . Thanx again for great video.
have you ever had clutch bearings make a whine noise that goes with rpm?
Do you have part number of the spring at the base of the hub? Can’t find it anywhere
Awesome video! I’m replacing a full clutch kit in my 07 R1 right now and found the boss assembly broken around the rivets! So now i guess im going to have to get a new assembly. Any tips on replacing or what causes that to happen? Just want to make sure I’m not fixing the surface issue. Thanks ahead of time!
High heat and stress will cause it to break. Was the clutch slipping at all? You should be able to tell from the plates. Dumping the clutch to do wheelies? This will cause that too. Also, if it is over-torqued when installed. That will also cause that issue.
@@EugeneAlston I appreciate the reply!
yeah clutch had been slipping for a while but my ride time was low because of work at the time.
When I pulled out the clutch plates there was some really uneven wear as well. I never popped clutch only roll wheelies in 1st and 2nd at like 70mph or more.
It was the stock setup. I only have like 30k miles or so on it.
Same issue on 2013 Yamaha R1 the boss assembly cracked from 4 different places, luckily the boss assembly didn't shatter into little pieces causing the motor to lock up. The boss assembly rivet system gets little loose with mileage so the rivet play builds a backlash, while riding when you are in negative torque and all of the sudden you your gunning the bike the boss assembly slams against itself which sends too much vibration to the whole boss assembly which causes it to crack. Just buy a new boss assembly with new clutch along with new oil and oil filter you should be good. If the boss assembly shatters under load your f**ked.
What is the stack height spec on a 2007/8 R1 ? GR8 Video
Took an old clutch plate and disc, drilled 4 holes in them, riveted them together, and put it in the basket, to hold the works together, while torquing the clutch nut down.
2017 FZ-10 Question replaced clutch (plates & fibers) due to the bike pulling off in gear while at a stop with the clutch pulled in, as well as finding neutral being an impossible task while the bike was stopped, Solved those issues, but there is a persistent chatter while in neutral when the clutch is let out seemingly similar to this video. In addition to that the while the bike is moving the clutch area sounds like there's at leased $3.00 in quarters in there, its a ton of noise and chatter also after 30 or so min of riding false neutrals and hard shifting starts becoming a thing? Took it to a shop and they charged me $300 to pull the clutch out inspect it and tell me that "all seems normal and it is what it is, its just a noise my bike makes now" so hoping you have an idea about what could be happening?
Have any pictures you can send me? If you share on email, I'll reach out.
Which would be a better clutch stock or kevlar for street and track ,also looking for what would last longer
Kevlar, handles the higher heat temperatures much better.
So I dismantled my 07 R1 and found the rivets loose. My clutch rattled when engaged. There's a groove on the outside of the boss at the back by the flywheel. The clutch rings look good, the springs in the basket are as noisy as ones on this video as well. How would you proceed?
More than likely it is still mechanically sounds but will make noise. You can put spacers behind the springs to cease the rattle. Personally I would just leave it.
Awesome! Thank you! I've been looking for an answer about it all day!
@@cblasius77 Did you fixed the sound? If yes, how? Thanks
@@IarHead have not confirmed. Having an issue getting any tension in the clutch handle. No resistance even with cable adjustment. Haven't dug further yet.
i have a 2001 r1, I've changed the clutch and now when I drop the clutch at a set of light to pull away quickly it bogs... then it takes off, and its near impossible to do a clutch wheelie as it feels spongy, sometimes feels a bit jerky at low rpm in 1st gear... any ideas what it could be? I replaced steel and friction plates and diaphragm spring, also I changed oil to a silkolene pro 4 10w-40.
If it is “spongy”, it sounds like it may be slipping.
When you say “bogs”, do the RPMs drop? Or do they increase but the bike doesn’t go anywhere?
Sounds like you may have 2 separate issues going on that may not be related to one another.
1. Spongy clutch feel/slip
2. Engine issue.
Keep in mind that engine oils with moly may cause the clutch to slip.
@@EugeneAlston it doesn't slip, as soon as it's fully dissengaged it pulls hard right up to limiter and even when changing gears it's fine. Just say I'm at 3/4k and launch it I'd have to slip it like crazy to keep the revs up or it'll seem like it's bogging out. I did change the oil to a fully synthetic from a semi I wonder if it's causing a issue?
@@EugeneAlston by bogging I mean the revs will drop no power and then bang off it'll go almost like it has a limp mode
Definitely doesn’t seem like you have a clutch issue at all.
I would focus on the engine. Specifically diagnose and ensure proper air, fuel, and spark operation.
ok thanks I will get it checked
Great video Eugene, I took off my clutch basket to inspect it as my 2012 R1 had a rattling sound coming from the clutch. My boss assy was cracked I replaced it but now I have a loud knocking noise. Is there a possibility that my engine timing went off from removing the clutch basket? I already removed the clutch cover to inspect installation of clutch basket everything seems good.
Please help, thank you in advance!
Check that the gear that spins the oil pump is timed correctly.
@@EugeneAlston ok, I’ll be checking it later today. Could the cause be that I didn’t use the universal clutch holder tool to loosen the clutch boss nut? Also, before installing the clutch basket is it mandatory to turn the crankshaft so that the crankshaft bottom portion of the piston can’t be seen?
@@ezequielceja6360 I’ve never used the clutch tool. Not needed.
Just make sure the gears and splines are lined up. Especially the oil pump gear. That’s the hardest part.
@@EugeneAlston they weren’t lined up man, i lined them up and fired her up with no luck, might be too late 😭 time to send her to the shop to see if she can be saved🤞 thank you for your help 🙏
@@ezequielceja6360 You are welcome. Now you have the knowledge. Worst case scenario you will have to replace a part. Not the end of the world. Best of luck! 👍🏿
Hlo sir
