I noticed a new noise comming from the foreward top end. Sounds sort of like a playing card in the spokes of a bicycle. I stopped at the dealer on my way home from work and had the tech test ride it, and he took into the garage. he came back out with it and said it sounds like an exhaust leak to him but couldn't say for sure. I scheduled an appointment for next week. Has anyone else had this problem. I only have 1300 miles on it so far. | ||

Does it happen only when the engine is under load, or can u put it in neutral and rev and still hear it? If u can hear it during idle and/or in neutral, as well as load then u might have a problem, because thats what mine was doin right before it broke the valve off and went threw the piston and took out the bottom end...no worries, nothin like brand new FREE 7300$ engine(after parts and labor), GOTTA LOVE THE WARRANTY!!!

Mine makes the same noise. I can only notice it when the bike is warm and cruising or lightly accelerating in any gear. I have 4800 on mine and its been doing it for a long time I was just going to ride it out for 2000 more miles and bring it up during the service. It sounds like an exhaust leak to me but its hard to tell because the engine is so noisy. Let me know what your dealer says jelomadnes | ||

Do either of y'all have the inner airbox removed? Mine makes a noise kinda like that, I assumed that it was the crankcase vent... R | ||
| Jelomadnes |
I hope it's not a valve. And to answer the question, My airbox is bone stock as is the rest of the bike. And you can here the noise only when under a load, not when it's in neutral. | ||
| Stlcr09 |
Mine started doing it before I had removed the inner airbox cover. I had assumed that it was an exhaust leak at the head so I checked the bolts to see if they might have come loose but they were all snug. I will try to somehow muffle the crank vent tomorrow. I guess it could be that loud. Either way, I have a fix for mine on the way... Just ordered the FMF for it a couple hours ago | ||
| Slypiranna |
Yea, Turn up the "radio"! LOL! That'll "fix" "it"(?)(!)!  You just gotta love some internet posters... Entertainment for the masses. | ||
| Slypiranna |
Thread starter/ Drop your bike off @ the dealer and forgo what ifs. BMC and the dealer techs will figure it out and save you a lot of drama in the meantime. FWIW. Hope all works out well. | ||
| Stlcr09 |
I guess you didn't like my joke slypiranna. Anyways, I just remembered that my old SV1000S made a very similar noise under the same conditions; hot and cruising or light acceleration. It turned out to be the slipper clutch and there was absolutely nothing wrong with it. But thats not going to keep me from asking the dealer to diag the noise when I take it in. Just Curious, Everyone who's bike is making this noise, What is your build date? Mine is OCT 08 | ||

Ok, a little update here. I just picked up my bike up from the shop. Buell tech said,"the exhaust isn't leaking, and that funny noise is still there." He then said, "It's gonna be a nice weekend, no rain, if it were my bike, I'd ride it reeeeal hard." Bottom line, he can't fix what ain't broken...yet. I'm inclined to think that either I got a valve that's bad, or one of the noisier models  . Either way, I'm heading for the North Cascade Hwy this weekend, it should be fun.

I hear ya Jelo, Mine is an '09 with 4600mi. Oils been changed 3 times and the only visable stuff on the oil drain plug magnet has been some ultra fine gray matter. The engine is much noisier than it's ever been,, kinda embarrassing really,, the engine noise ain't selling any 1125's to my friends either. Early on the engine had a sublime rocket accell with wide open throttle, up around 8000,, it was Friggin' Awesome! That is all but gone now,, barely a detectable hint of that feature. I ride the bike as hard as I can, have a 1/2" chicken strip. The power thump of the engine was much softer when it was newer under hard accell. Now its a much sharper thump and it feels like its working harder getting to what it had. I don't know fellas,, I'm a bit concerned about its valve train system,, somethings going on there. And the thought of the proceedure to inspect that area is really making me dislike this bike. | ||

Mine makes the same type noises that I have commented on before, almost like the valves in a car ticking when they are out of adjustment. It was REAL bad with the Mobil 1 V-Twin in it. I switched to Amsoil 20w50 and most all the noise is gone. I still can hear the slightest bit, but not like before. I suspect most of you are used to IL4 engines that really don't make that noise. This is my first Buell V-Twin so it took some getting used to. I can tell you from owning a couple of Harleys that all their engines make similar noises and I never had any issues. I highly doubt anything is wrong with it, it is just the nature of the v-twin. Go change your oil to the Amsoil Synthetic and see if that helps, did wonders for mine. | ||

Metal, My 09 was very very noisy from the day I bought it (Pointed out by another 1125R owner, even after its first service by the dealer), embarrassing to say the least, I didn't know any different, and the salesman told me it was normal. I never knew you could hear the exhaust until I listened to another one side by side! The rotor nut in the transmission needed tightened to the updated torque specs, this was not known as a street issue, but a track bike issue. Mine was also down in power (also pointed out by the other 1125R owner after he took mine for a ride), and the noise sounded as though it was coming from the top-end. The oil did not show any evidence of the issue either. I would have this checked, mine was night and day with the noise and power after the repair (it still chatters, but much less)! Just an idea!

I ordered some Amsoil just yesterday, mostly because of your post. I have been using it in my 99 VFR 800 for a while now and it's doin' alright. Course the VFR is a "mute" compared to this thing. | ||
| Metalrabbit |
Thanks Tbenson I'll ask about that,, "Rotor nut in the trans" | ||
| Avc8130 |
Did some searching...can't find anything on "rotor nut"... ac | ||
| Jpowell490 |
Let me know what you think when you change it Metal, I know it will help out. | ||
| Metalrabbit |
I called over to where I bought my '09 1125 to ask about the "rotor nut" re-torque, said he'd call me back but he hasn't yet,, 7:00pm here now. I got to ponderin' about the loss of the bikes mid-range zip. Started focusing on the throttle,,specificaly the TPS sensor reset like you guys have written about on this site. Sure seems a lot better in the powerband than yesterday when the power pulses seemed awfuly sharp and outa step. Today the pulses were much smoother and the speed came on much like it did when it was fairly new. It still has a fair amount of clatter noise but at least it's not running bad too. Cool yeah?

How did you adjust your TPS? I saw Blake had posted a "how - to" on the 2008 and up, but I tried it and it doesn't work. Mine is sitting at 2 when throttle is completely closed, so it should be 0 right? Mine is missing a bit in the 4k range just cruising on the interstate, so I am wondering if this could cause it. | ||
| Xbswede |
I wonder if that miss in the 4k range is due to the ECM learn feature and O2 feedback. Since disabling my O2's and locking my AFV I have not had any misses. I use to also have misses on my XB in the 3000 rpm range. Personally I really dislike the learn mode of these bikes. it really made it difficult going from cold to hot days with slow re-learn time. | ||
| Jpowell490 |
I have noticed that miss more and more, seems like it is getting worse, all I need. I used to know a lot about the Harley ECM and tuning with the Super Tuner, but I don't have a clue what you use for the 1125, maybe someone can post a short list of what is needed. Thanks, | ||
| Zac4mac |
JP - normal range for the TPS is 2% - 100%, Z | ||

Possibly listed as the crank bolt, the rotor nut is located under the trans cover on the clutch lever side of the bike, it holds the crank bolt in place. By my understanding there was a bulletin on this issue sent to the racing teams to retorque the rotor nut to the new specs. The service tech which repaired mine had no idea what the issue was, but knew there was a problem, he received the information from Buell Tech for the fix. The Tech stated mine was very loose when they went to remove it, they retorqued and applied new loctite. So far, so good! I did not tear into the bike myself, this is the information I received on the issue and on the repair. Troy | ||
| Jpowell490 |
Thanks again Zack, Guess it is fine then, will leave it be. | ||
| Metalrabbit |
I suppose the 2% is to allow for idle yeah? | ||
| Metalrabbit |
Well, Rocky at Paradise Buell couldn't find anything that refered to re-torque of a "Rotor Nut" on the trans in his info. And I still haven't got my shipment of the 20/50 Amsoil order. My 10W-40 order for my VFR was here almost the next day,, waiting  | ||
| Tbenson |
By my understanding, if you remove the cover on the clutch side, it is located right there? When I take the bike back for them to fix the leak I will ask for more info on what they actually tightened. Better yet, I will call them for the info, and let you know. | ||
| Tbenson |
Metal, Spoke to Hales, they stated the whole clutch assembly was taken apart, on both sides of the bike (both covers), and retorqued with new Loctite. They called it the "Clutch Nut" this time, along with the "Stator Nut", which was also retorqued with new Loctite. Once again, this was a known issue for the racing teams, not for the street bikes. I hope this helps? Troy | ||
| Metalrabbit |
Rocky did mention a retorque in the stator rotor nut area (can't remember exactly what he said) for a shaft that has been machined different than the others. I doubt very much than I have a problem there due to the TPS reset having such a significant change in engine noise and performance. I think the engine management system is largely responsible for some of the freaky ways this engine runs. It's like trying to make an Indy Car run at any altitude, any air density, downtown traffic, freeway, track day, commuter and still pass an EPA testing facility! For the sensitive, picky motorhead, this engine is going to be a bit of a trial for you,, I know it is for me. | ||
