For those of you that don't understand spanish there it goes the translation of what he says:
main guy:
"Hello
I commented on a post that I haven't been able to install a dry clutch kit on a 848
I've already got it, here it is"
guy in background:
"brought from United States"
main guy:
"brought from United States through ebay
1500 euros
I'm gonna show you how it sounds with the termignoni and .. you'll be amazed"
guy in background:
"go go ... go go"
main guy:
"It sounds ****ing awesome
I made it myself"
girl in background:
"removable, isn't?"
other girl in background:
"Sandra says is removable"
Cheers :thumbup:

Hi there, I’ve got the exact same noise on my 2004 R1. Did you ever find the issue ?

If you read through the thread, the suggestion was something clutch related, most likely worn (out of spec) springs. If your noise goes away with pulling the clutch lever, then a clutch investigation or rebuild is in order. If the noise is not clutch related, if you can post a video we can take a crack at guessing or maybe even successfully identifying the noise. If it is cam chain slap, you must stop running the engine now.
BTW, this is an FZ6 site, but we’re pretty smart fellas.

Hi there. The noise is identical to the one in the video lone posted, I will try post my bike too. I’ve rebuilt the whole clutch assembly with new clutch fibre plates and steels. Replaced clutch basket with lower Milage one (still has loose springs in the back of the basket but thought this was normal). Carried out valve clearances and exhuast valves were pretty tight. All adjusted and now okay. Carried out throttle body sync aswell which has decreased the noise slightly but still very noticeable. I did think it could be a clutch basket issue which most people say but the crank constantly rotated the basket so no matter if you pull in the clutch or not it will still make the noise ? Mine only the noise below 1700rpm with the clutch lever out. Exactly like lones problem. I’m just running out of ideas at the moment and with the noise completely disappearing when the clutch is pulled in directs me to something gearbox related.

When you say that the springs are loose, what do you mean by that? Did you measure each spring and compare that to the service limit?

No but I purchased a brand new one and when it came the springs were loose I took it to Yamaha and asked the technician if this was normal and he said yes. If it was the springs in the back wouldn’t that make a constant sound ?

The springs in the basket get assembled with a good about of preload, about 10%. If they are rattling, they are either out of spec, or the wrong part number. Did they appear shorter than the ones you removed? Were all of the springs the same length?

The correct part number is 90501-230A0-00. The parts are available at Revzilla. I would remove the spring you have and measure them and then compare this length to the service limit. If they are short, replace all six.

I will do that but I just don’t understand if it was those six springs it would still make the noise with the clutch lever pulled in.

Because when the clutch lever is engaged, all six of those spring are compressed.

Thanks so much I’m beginning to understand. So the springs are under pressure when you engage the clutch because the clutch (basket) is not under pressure from driving the gearbox through the steel plates ?

How can the springs be compressed when all the lever is doing is separating the friction plates from the steels. The outer basket is still moving at the same rate just now not connected to the input shaft.

I know how a clutch works lol. What I’m saying is the springs on the back of the basket can’t compress when the inner hun is disconnected. It’s impossible. The springs are constantly working to help put smooth drive through the input (as you can’t constantly keep a smooth idle, everyone knows that). You’ve sent a animation which doesn’t mention drive cushion springs on the outer ring gear of a clutch basket at all don’t worry thanks for the advice but I’ll try the trained technicians next. Thanks though.

When the clutch lever is engaged, the springs fully compress. When you release the clutch lever the spring return to their rest position. In this position they should remain preloaded. When the springs are out of spec, or are too short, they will rattle in this position.

Think we are on about different springs. I was on about the ones in the back of the clutch basket
