I'm noticing that when I'm in neutral and let the clutch all the way out I'm hearing a faint rattle. Anyone have this? | ||
| Tbowdre |
FAINT!?? mine sounds totally different at idle in neutral clutch in versus out.... thought it was normal! okay... i still think it's normal | ||
| Cataract2 |
Yup, it's normal. Mine has made the noise since I got it. | ||

thats good to know i am guessing gear lash changes so less moving parts, i noticed that and several other strange noises, not like the aircooled motors used on previous buells, just takes getting used to the different sounds these new motors make...  | ||

It is almost certainly the clutch plates rattling. Sounds like a dry clutch only quieter right? | ||

Is it a rattle or a metallic squeaking noise? Mine is making a weird squeaking noise like metal on metal vibration. I got a similar sound from my mustang when the exhaust bracket starting contacting the frame, but it was much, much louder. Sounded like a giant cricket chirping in my trunk. | ||

Mine does it too thought somethin was weird with it but figured I'd wait till spring to have it checked out | ||
| Rpm4x4 |
Its not that faint lol. Mine does it too. Im assuming that its normal. | ||

Noise from the primary output gear is my guess, same sound as my Victroy makes and it is primary gear drive not primary chain like the bar and shields. (Message edited by captainkgb on November 22, 2009) | ||

Its cause when your clutch is in your not getting the same amount of spin on your counter/main shafts in the tranny. let it out and they spin up but have no gear contact | ||

The noise is gear lash. V-twin engine pulses with a light flywheel and you hear the gear lash. Don't worry about it. You don't hear it on the XB's because of the heavy flywheel. When the clutch is pulled in (disengaged) the noise is less because the clutch is taking up the engine pulses and not letting them transfer through the transmission gears. My Ducati trans sounds the same. | ||

If the bike is in neutral and the clutch is released,there is no way that the engine could cause noise from gear lash. What you guys are hearing is the clutch plates rattling. The concept is the same as with a dry clutch but with a wet clutch it is quieter. http://www.youtube.com/watch?v=gcIr75i_h_M http://www.youtube.com/watch?v=UsnNgU8pKoc | ||

I've just learned to realize this bike is noisy. The day my bike doesn't clunk and rattle is the day I'll be concerned. | ||

+1 for clutch plates if you've ever rode a bike with a dry clutch (most ducati high end models) or a bike with an open clutch basket (every tom,dick,and harry's basket build chopper has one) you'll recognize this noise. The wet clutch will "deaden" the noise but its still there, if you've ever had a H-D primary drive cover off, and ran the motor for whatever reason (dont do what I just said, its really dangerous, and messy....) you'll hear the same clatter on any bike in neutral and clutch engaged. There's no weight or force put on those plates, so they rattle ever so slightly because of no load on them, no gear...will rattle. These are the noises that make me feel at home, silence scares me on my Buell, I have an XB but still.... Brings up an old saying: Q: what's that noise? A: I dunno, sounds fast Q: what's that smell? A: I dunno smells fast (ok maybe not on any bike, but you get the picture. If your really bothered try some searches on oil for your 1125, maybe a high quality oil will quiet things down to a "less-noticible" volume.) (Message edited by clutchless on November 23, 2009) | ||

"If the bike is in neutral and the clutch is released,there is no way that the engine could cause noise from gear lash." Not true. Do you think that in neutral nothing in the trans is moving? When the clutch is engaged, the input shaft is spinning, along with gears on the input and output shaft. Nice video of a very worn dry clutch. | ||

Okay, fair enough, so there is a theoretical possibility that pulsing from the motor is causing noise from gear lash. However, the lash within the clutch is going to almost entirely absorb any pulsing from the motor and more importantly, is going to make noise as a part of its design while gear lash would have to be significant enough to be called a flaw if audible at idle. | ||

The 1125 is as close to a no holds barred engine as possible and still be streetable and reliable...no compromise straight cut gears, etc, etc....it will be noisy...it's a sign of strenght. | ||
| Greenflash |
As we Ducatisti say "Loud Clutches Save Lives"! Yes, I do have that T-shirt in my closet. But I'd like to add the new Buell one that says "Loud Fans Save Lives" too. That noise difference between clutch in and out on the 1125 just makes me feel at home too. No worries. | ||
| Dentguy |
However, the lash within the clutch is going to almost entirely absorb any pulsing from the motor.... Not trying to offend, but  If you think that engine pulses are being almost entirely absorbed through clutch lash, with the lever out (clutch engaged), I've got no comment. We'll never see eye to eye. Enjoy. | ||

Dentguy, we don't need to see eye to eye here. Regardless of whatever is happening in the transmission - regardless of whether engine pulses are absorbed at the clutch, the fact is that the noise being discussed is the clutch and not gear lash. If you are going to imply that I, or anyone else here is wrong at least make an effort to explain the facts instead of just make smart-ass insinuations that I don't know what I am talking about. I'm all for a reasonable argument. Prepared to learn something and acknowledge when I am wrong or don't understand something. So, if you want to act like an adult and actually discuss the mechanics, I'm all for it. Otherwise go somewhere else. (Message edited by ratsmc on November 24, 2009) | ||

I was going to leave this thread alone, but I think I should respond to your comments. So that there is no "smart-ass insinuations" that you don't know what you are talking about, I'll try to be clear. If you think this comment you made is a fact, "However, the lash within the clutch is going to almost entirely absorb any pulsing from the motor.... " you don't know what you are talking about pertaining to that comment. I assume you think that it is a fact or you wouldn't have posted it? If you do think that is a fact, I don't want to have a discussion about engine pulses, clutch noise, clutch plate to basket and drum clearance, transmission noise, gear backlash, etc. with you because it will be useless in my opinion. Then in your last post you state "I'm all for a reasonable argument. Prepared to learn something and acknowledge when I am wrong or don't understand something." and this "Regardless of whatever is happening in the transmission - regardless of whether engine pulses are absorbed at the clutch, the fact is that the noise being discussed is the clutch and not gear lash." So, you're up for a reasonable argument, prepared to learn something and acknowledge when you are wrong or don't understand something. But, you're not wrong because this noise is definitely the clutch and not gear lash? Obviously it would be a waste of time for me to discuss it any more with you since you know for a fact that you are right. The truth is that neither of us know exactly what the noise is because it's not in front of us. As for explaining facts, why don't YOU explain how the clutch (as you said) almost entirely absorbs any engine pulses and why it can only be the wet clutch making noise and can't be anything else instead of posting a few videos of worn Ducati dry clutches (one that is very worn) to try and get your opinion across. Here is what a dry clutch sounds like when not so worn so that people who aren't familiar don't think that all clutches are that loud. One with a cover http://www.youtube.com/watch?v=c_-LD1cUf6g One without http://www.youtube.com/watch?v=ZftlaSIXMvI I don't know how long you have visited this site, but it looks like you've been registered for about 19 days. If you post something that is BS, like your comment at the top of this post, someone is going to call you on it. Get used to it. As for going somewhere else, I don't think that is your decision to make. Obviously you think it can only be the clutch and I don't agree. We can leave it at that. | ||

The fact is, I am willing to admit that I am not an expert when it comes to transmissions. That said, I have had enough cases apart to have some understanding of what is going on in there. So, to that I was willing to engage in a discussion of why the sound could be gear lash since I had never once experience gear lash making noise at idle. And yet, aside from stating that the noise was gear lash, you put forth no explanation as to why that could be the case. Instead, you went to nothing but half-jokes about what I know and don't. That isn't discussion or making your point, it is avoiding it. Given that the noise most of us hear when on or next to an 1125 clearly sounds exactly the same as clutch rattle and it is loudest when you are near the clutch cover, I stand by the conclusion that it is most probably what this guy is hearing. If you have any evidence that it isn't, share it. The point is, you don't need to denigrate those around you to make your point. If we are wrong explain why. Simple, huh? | ||

mine sounds like a bunch of rocks rattling around in a hubcap, it's done it since new, i'm assuming it's normal... | ||

"And yet, aside from stating that the noise was gear lash, you put forth no explanation as to why that could be the case." From my first 2 posts above.... The noise is gear lash. V-twin engine pulses with a light flywheel and you hear the gear lash. Don't worry about it. You don't hear it on the XB's because of the heavy flywheel. When the clutch is pulled in (disengaged) the noise is less because the clutch is taking up the engine pulses and not letting them transfer through the transmission gears. When the clutch is engaged, the input shaft is spinning, along with gears on the input and output shaft. "Instead, you went to nothing but half-jokes about what I know and don't. That isn't discussion or making your point, it is avoiding it." It wasn't a half-joke. You said something that made me laugh and I posted a clipart to represent how I felt. I also said that I have no comment if you think what you said is true. I wasn't avoiding anything. "The point is, you don't need to denigrate those around you to make your point." I wasn't trying to denigrate you to make a point. You said something incorrect that made me laugh and I called you on it. That's it. This is going nowhere and I shouldn't even be replying. It has become a back and forth that's not about a neutral rattle and polluted this thread. I'm done. Enjoy your Thanksgiving holiday. Sorry for hijacking your thread Sfinton. | ||

"Sorry for hijacking your thread Sfinton." Agreed. |
