The first 900kms have been awe inspiring to say the least! I have a few items for discussion: - Ambient temp reading is way out of whack. I assume it has to do with the heat the bike produces, anyone else notice this? - There is a foot long section of belt that has frayed on the outside edge, the dealer has looked at it and said not to worry its normal. - On decel there is a "whine" that I can't quite pinpoint the source. Any ideas? - Not sure if anyone has had to do a tire change yet, but it doesn't look to me like the exhaust is a jack point like the XB's - I am guessing universal stands of some type? - I am very unimpressed with the durability of the diamond blue finish so far. I have 3 scratches in my front rim right down to the aluminum and 1 on the rear rim. I have only been riding on the street, granted we have sand and gravel on the roads from winter still, but my Amber wheels in my Firebolt never nicked or chipped... All in all I can't believe how much this bike improves upon the XB platform. What a dream to ride.... | ||

My only problem has been a charging issue, the whine might be the chain drive for the cams, ambient temps on bike seem to never work right, I have seen someone make metal pieces to go on a bike jack that matches the pipe to jack it up, others have mentioned the belt issue and have shimmed the belt guard that is causing it, I am changing to the ulysses wheels because I do not like the blue and probably going to try to paint the frame black, overall an awesome bike just got some bugs to be worked out.

"On decel there is a "whine" that I can't quite pinpoint the source." I have noticed that too. I was thinking that it was the fans changing pitch when the pods go from positive pressure(at speed) to negative (at below 35 mph). I could be way wrong though. I`m still loving mine too! | ||

Whine...water pump. | ||

Edmbuller: About 25mph and decelerating, I get this whine in any gear (or neutral) . I think it's the belt/cush drive in some sort of harmonics. I did notice that coating on the stock wheels damaged easily taking the front off. But I thought it was just me being ham fisted... | ||

- Ambient temp reading is way out of whack. I assume it has to do with the heat the bike produces, anyone else notice this? If you are at a speed above 50mph and you are not in the draft of other vehicles (heavy traffic) it is somewhat correct. I spoke with Buell person about this and got the answer that the ambient temp reading does not affect the ECU at all and it is just a reading for the rider's edification. - There is a foot long section of belt that has frayed on the outside edge, the dealer has looked at it and said not to worry its normal. The lower belt guard may have been rubbing on your belt. Check to see if it is an even 3mm to 8mm gap on the rear sprocket side (either value is in tolerance). If the guard rubs, loosen the bolts and tighten them. That might be enough to straighten the guard. If not, shim the guard on the inside with a thin washer. - On decel there is a "whine" that I can't quite pinpoint the source. Any ideas? I think they all do it. Mine does. I hear it when the motor is good and warm and if the ambient temp is over 60. I heard it more when new and less now at 5000 miles. - Not sure if anyone has had to do a tire change yet, but it doesn't look to me like the exhaust is a jack point like the XB's - I am guessing universal stands of some type? There is a JackPoint under the exhaust. You can see the reinforcement in the cutaway picture of the exhaust. It is located directly down from the rear chassis exhaust mount. Disclaimer: I have only used rear and front stands when replacing tires. - I am very unimpressed with the durability of the diamond blue finish so far. I have nothing to contribute there, other than I have not treated the 1125R differently than my XB and in my use and handling of it - no scratches so far. | ||

thanks for the input guys, just got back from a ride (still pretty cold up here) and this bike just gets me giggling in my helmet. | ||

Don't any of you remember the gear sets for the chevy 350's that took the place of the timing chain??? We used to install the gear sets to get that 'blower whine' 'cause it was cool! I'm thinking the whine is from the cam gears, the water pump is and should be pretty much silent. It sound almost like the chevy's did with the gear sets. JJ | ||
| Dalton_gang |
Sheridan, you could be right. And yes the blower whine is way cool. I happen to be blowing 12 psi into a SHM balanced and slightly modded 4.6l must.gt. People who know what the sound is constantly give me a thumbs up and beg for a burnout. (which I am always happy to do) People who don`t think that my car is screwed up. | ||

Im with Bearly on the whine. I would call it more of a howl on decel, and I only notice it in town at slow speeds. Im glad to hear other have it as well. My theories were either cush-drive related, or front brake. I went from a tuber to the 11, so this is my first experience with ZTL. | ||
| Xb9 |
Yea, it's more of a howl and I think it's the belt or cush drive. I'm betting it will diminish or go away with miles as the belt wears in more. | ||
| Dtx |
I've got the howl too. It's the nature of this beast! | ||
| Jpfive |
I think that the 'howl' may be related to the counter-balancer shafts. It is similar to the sound that my old Voyager made when the balance shafts were being adjusted. Jack | ||

Riding around my little town, the howl/whine makes people turn and see what's coming after them! I'm not worried about it. I use to worry about little noises when I first bought my Uly which was my first Buell. After I bought the Micron Exhaust, all those noises went away, now no more worries.  | ||
| Sheridan_bueller |
If it's the belt or the cush drive, why does it do it when out of gear and stopped at a light? The cush is just some rubber between some cogs, like a lovejoy coupler. It's the cam gears. If it were anything else it would change pitch and tone in different gears and at different speeds 'cause the belt would be going faster or slower and the cush would be driving the belt...on mine it is always the same whine in every gear at same RPMs. I can hear it in 6th gear when cruising the same as in 1st going through town. Just my assumption. JJ | ||
| Bearly |
We must be talking about two (or three) different noises then. Shoot everyone hear must be talking about a different noise. The things too quit, I can hear the tires on the pavement! (Message edited by bearly on April 05, 2008) | ||

Sold my Harley for this beast. I like the noises and vibes. I guess I grew accustom to them with my TC95 and the valve train noise. I say just ride it, maintain it, and Love it. I haven't ridin a bike yet that didn't have corky things it did or liked for you to do. Its personality! 2 cents worth | ||

Good to see that some have finally brought out the similarities between this bike's timing set and a gear drive or blower whine. Some of the older Harley bikers who have had blown cars have commented the coolness of that sound on the 1125R. I noticed that sound when I first test drove the bike. When Eric Buell sent out that first information packet to all previous and current Buell owners last July/August I studied that packet and knew it would have that sound by looking at the valvetrain. That was a definite plus in my book as I have stretched out to mainly timing chains in my cars. That is why my 1988 Mustang has has gear drive now to prevent a stretched chain. Thus preventing bent valves from a high lift camshaft's timing being slightly off from an already small piston to valve clearance with the stretched out chain. Just my little rant of that whine sound and glad others know of the sound and coolness of it. Toby | ||

Mike, Before changing to the Ulysses wheels, consider having them re-powder coated to get the color you want. The Uly wheels are quite a bit heavier to allow use on unimproved surfaces. Pete at Grandstand Designs (one of our sponsors) does powdercoating AND he rides/races Buells. http://www.grandstanddesigns.com I've bought some stuff from him very recently and he's easy to get with an email. Shoot him an email note (or HECK - use the phone!) and see if re-coloring with new powdercoat would be better instead of getting heavier wheels just because they are the color you are looking for. | ||
| Spatten1 |
Could the whine be the primary gears? Are they straight cut? | ||
| Baggermike |
Slaughter I know the front wheel is heavier not sure about the back wheel, I am not sure it is the color I want and I also live in Boston with big pot holes and have dented the pm wheels on my 97 lightning, I am sure my son is not going to ride his bike off road and has a softer ride so less chance of him denting a rim than on my bike, I would like to know the weight difference in the wheels, I also do not know what color to get and thought by putting on the wheels it could give me idea's on if I like them or another color would be good, I also was thinking a stardust silver but the cost of the wheels is the cost of the tire changer. I will check out that website and see if there is a color that I like so thanks for the info. I was on another website and did not like any colors they had, I think I am going with a stealth fighter theme and will paint it grey or matt black with graphics to look like the painted sheet metal of the jets and other markings, I got all summer and fall to figure it out and thinking more towards matt black because I want to get the kick ash air box cover so I can light up the inside. | ||

It could be the primary gears but unlikely as they are quite different in size. The cam gears would be more 'whiney' 'cause they're equal in size and the meshing of both gears is the exact same frequency and the load equal on each tooth. I'll leave this alone now. I love the sound. It gets noticed when going through town, just like it did in the days of real engines in real cars. JJ | ||

I've heard many jap bikes and other brands make a whining sound also on decel. Even heard in from some Harley's. So no concern on that one. | ||
| Xb9 |
The howl I'm talking about only happens between 25 and 30 MPH, and it is not in sync with the engine RPM, it comes and goes with speed. I'm 99% sure it's the Final drive (belt). | ||
| Slypiranna |
Mine has a little noise coming from the belt relative to ground speed only and then the real whine, again, relative to ground speed only coming from the front brake/rotor. No matter the engine speed, the same occurs on every decel. I've never heard any gear noise to what has been called similar to a timing gear drive installed in a auto v8 engine...or that related to the engine. No problems at all with either...2k miles. | ||
| Slaughter |
Valve train noise in engines is a definite possibility but one thing I noticed is the amount of intake noise. Maybe if you're riding with a helmet and ear plugs, it MIGHT partly be the intake? If you're not used to it, it really is loud and depends on throttle position AND RPM. If you're rolling off, the butterflies are partly closed and if the engine is still spinning, I'd bet the sucking of the HUGE intake is making a HECK of a racket. (no, I don't have an 1125R yet - just 5 sessions at Inside Pass so I'm working on 6 month memory now) (Message edited by slaughter on April 06, 2008) | ||

I think Steve(Slaughter) is pretty close to being right. I live near Hill AFB and when the F22 Raptors are landing and shutting power on the approach they sound remarkably similar as does mine. I just love riding my own street "Raptor" Bob, flying low in Utah. | ||
| Baggermike |
Hey Bob this is funny I never named a bike so I was thinking if I were to name it what would I name it and a raptor F22 was the most likely, I have a Akuma stealth fighter helmet and I want to paint the bike to match the helmet so I am going with the jet fighter theme and was looking at the raptor as something to copy, there was a couple of jets I like and two were experametal and had a matt black and a grey, I like the matt black look, also found exhaust that look like jet engines the same company that make the spinning guns makes these exhaust but I do not want to use them. I will be done by the end of May and then paint the bike in the winter, should look really cool and got some good idears. Mike | ||

- On decel there is a "whine" that I can't quite pinpoint the source. Any ideas? Could be the straight cut gears in the transmission as opposed to helical cut gears. Those of us that know what a Muncie "Rock Crusher" 4 speed sounds like know what I'm talking about. Straight cut gears produce a distinctive whine but are generally stronger as a final product than their helical cut counterparts. If I'm not mistaken, I think the Harley Davidson Destroyer used straight cut gears as well. Savor the whine. | ||
| Cutty72 |
I've heard it too, not sure what it is, but I can hear it when coasting in neutral as well. |
