Got the 1125R Back today w/ the first service done and the reflash completed. One thing I noticed right off the bat, was the better throttle control at lower speeds. It wasn't really a problem to begin with ... but it is noticeably smoother now. I was also told that the reflash might help the gas smell since the fuel pump is cycling for half the time as before. | ||

calibration is not a fix all! I have discovered a deeper problem with the accel lag but will confer with Buell monday to verify. Please be careful when riding! Ummm. I call Troll. | ||
| Cataract2 |
For a first post. Yeah, troll. | ||

the biggest issue with low speed throttle when i picked up my 1125 was that the throttle cables had too much slack from the factory. after adjustment -much better. after disconnecting the emissions solenoid-better still(not so much effort to roll). i have noticed throttle cable slack on most of the buell demo bikes i have ridden. have not done the reflash yet. tim | ||

Why a Troll, maybe the truth hurts? While you're all crowing about this alleged 'fix' here in the UK, we've been told nothing - why? Meanwhile, the reputation of this fantastic machine is getting more and more tarnished with people saying they'd never buy such a flawed product. A great shame in my opinion. I'm hoping the 'fix' will cure mine riding like a two stroke when getting back on the throttle after deacceleration - I have to turn the grip about 1/4 and wait for the power to come in with a bang at 4k revs - is this the low speed throttle response/lag that people are talking about? | ||

>>>Why a Troll, maybe the truth hurts? Perhaps it does. I see your comments are based on "your opinion". The above post sounds like rubbish. 15,000 folks, most Buell fanatics hang out on Badweb which has been here over 10 years. I find it odd that a person shows up and offers as their first post a cryptic allusion to "discovery of a deeper problem". I know quite well some of the men and women working on this. There is no reason they would have shared any information with me but I'd be more likely to hear of it than a Harley mechanic. I have no opinion on the statement, it just sounds quite odd. What I do know, AS FACT, is that some really smart dedicated folks have gathered a lot of "real world" input from folks actually riding 1125R's on public roads. They digested and analyzed information while, at the same time, keeping their feet out of the quagmire of internet rumors, and produced an upgrade in record time for a motorcycle company. Quite impressive. Ever seen Honda or Ducati react that fast? Frankly, amazing. I also toss into my cognitive mix the the fact that real people who have had the upgrade are offering excellent reports. I also like the fluid way that some of the quirks of delivering the upgrade are being smoothed out quickly by great communication between dealer techs and factory personnel. Who knows if the guy is right or wrong. The statement is not supported by any evidence. Folks at Buell seem to not be aware of it. So me? . . .I'm basing my opinions based on the stellar reports I am reading and keeping and open mind. I'll be waiting to hear from the Buell Engineer after our mystery poster speaks to him on Monday. Court | ||

The only thing keeping me from jumping on the "troll" bandwagon is the Active Air Solenoid - you know, Sly's Silver Solenoid, hooked to the throttle for "noise abatement". We'll see. I do know, the solenoid has 3 DTCs(error codes) associated with it - hi, lo and no feedback. Says so in the Electrical Manual. Z | ||

I have had one instance of the throttle cables binding, which happened after my dealer replaced my inner air box (due to a broken lock tab - warranty). It felt a lot like our Brit owner described - and was dang near unrideable. My first advice for any owner experiencing lags in power on and/or power off, or a feeling of restriction in the cable, is to check for binding in the area of the solenoid that Zac mentioned - which is where mine was hanging. This is a separate, and very different, problem from what the EFI reflash is addressing. Jack | ||

I am scheduled for the reflash on Friday. Frankly, my bike is running so well that I am having second thoughts. The only 'issue' that I have is a momentary hesitation if I roll-on hard at about 3500 rpm. This disappears if I roll-on in a more deliberate way - a smoother technique, which results in no loss of power or response. Jack | ||

Just disconnect the cable and leave the solenoid there with the wires attached. Will not throw a code. Easier twist of the throttle, and no more lag at 3500 rpm in third gear. Easy fix. | ||

A little more post update feedback. The bike is running better than before and most importantly I no longer have an issue with the charging system running at a deficit during idle. As others have reported much improved throttle response in the low end. The surging has also been reduced between 2500 and 4000 RPM. There is still some slight surging, but much improved. By the way, I have never experienced any throttle lag (pre or post update). I also noticed some fan pitch noise changes on occasion. After further investigation I figured out this is indeed the result of one of the fans turning on or off. I have observed just the left fan running at idle. When I turned the bike off the right fan then kicked in and both fans ran for a short period before shutting down. I also noticed my Adaptive Fuel Values reset after the reflash. They were 100/100 at the dealership after the reflash. By the time I got home the Front was 90 and the rear was still 100. They were 90/89.5 prior to the reflash. The bike "seems" to be running a bit warmer. I caution you on how you interpret this as it is a very subjective observation, but at ambient temperatures in the 70's or below, it seemed to average about 175 prior to the flash and 180 after. I consider this an improvement as I thought the bike was running a bit cold in cooler weather as I always seemed to have to thrash the bike to get it to run warmer. In addition the calibration software version that was originally on my bike was different than the one on the service bulletin. Bulletin states previous version of B3HUS01W. The Printout they gave me from the Digital Technician II reflash states: previous version BUEWD0J6 and new version M3HUS02Y. | ||

Spectrum, thanks for the feedback, nice to get a good report on observations after the re-flash. Curious when you took delivery- maybe the very early ones had a different SW version from the factory? I would keep in mind with this re-programming it is like starting over, in that the ecm will need to learn all over again for the AFV to get dialed in. It may take a few miles and I would expect it to run better and smoother with time. | ||

After seeing the "no feedback" DTC for the A-A solenoid in the Manual, I'm a bit reluctant to disconnect it, electrically or mechanically. There are 70 discrete DTCs mentioned in the E-Manual, not all will show up in "Diagnostic Mode" but will show on a DT II (according to the tech that tried to re-flash me Friday). Loretta's running so well, I'm not ready to try "performance" mods, just personal aesthetics. Z | ||
| Jpfive |
Crowley, Yours wouldn't be the first to have throttle binding. What you describe is exactly the symptom mine had when the throttle cable hung up on the solenoid. It is easily remedied, and I think that a good 'search' on the forum will even get a picture for you. Check it out. Jack (edit) The binding on mine limited full throttle to less than 80% also. The situation you describe is in no way normal. If the throttle on my bike had been hanging when I picked it up, I would have refused delivery. As it is now - easily the best bike that I have ever owned. (Message edited by jpfive on May 04, 2008) | ||

Got my re-flash yesterday and put on about 200 miles since. VERY noticeable low-end improvement! Now pulls well from slightly below 3000, and no more surge while holding steady in the 3500-4000 range. Also, I could swear that the last 200 miles are also revealing the frame not getting as hot...Is that possible? Time will tell about the battery drain... Thank you very much, BMC!! | ||

HDwrench - I suspected as much. Stick around, sometimes new info takes a while to be accepted. Especially from a first time poster. The 1125R is chock-full of new technology and some issues are bound to take a while to show up and even longer to have a viable remedy. That's a major reason I "live" here. Again - Thank You, from me anyway, for the "heads up" Zack | ||
| Brad1445 |
Hdwrench, You will be punished for your honesty but as a Buell Customer I applaud your honesty as the the faster the development goes the faster I get a New Rotax/Buell. Thank You I will never believe those that say the 1125R was not rushed to market for the 25th anniversary. The parts bin appearance is only an outward sign that full development was not mature. Brave honest people like yourself will bring more people to the Buell customer family than empty praise. Lets get this bike to ROCK AND ROLL! | ||
| Court |
Precisely the reasons I keep an open mind. Having been around Buell for 20 years I've learned to never say never and to listen carefully. For fear someone would buy into the "rushed to market" chatter I took the liberty of sharing some schedules with some folks a couple years ago just to make certain some "independent" soul was aware of what was coming.  It's all good. . . . | ||

Hey all, I just want to say that my bike is one of the three that Hdwrench was working on last week. Like he said, the throttle lag continues, so I'm taking my bike back to him on Monday. He knows what he's talking about. The lag my bike is experiencing is significant enough to be dangerous, and I'm glad to have him on the job as this bike is my only vehicle. Cheers. | ||
| Ccryder |
HdWrench: I for one appreciate your concern and the way you carefully phrased it. I had mine flashed yesterday and previously I did have a pronounced lag between 4,000 and 5,000 rpm when I went WFO. Now I do not feel that. This lag would only happen 1 out 3 or 5 times when I would be reckless enough to need that much power and acceleration NOW!! Mine did surge very noticeably between 2,500 and 4,500 under light loads and steady throttle. This is now 90% resolved. Thanks to concerned Pros like Chris, yourself and, the Staff at Bumpus, this product is maturing very quickly and safely. Neil S. | ||

Big thanks Jeff and Hdwrench, a useful post rather than just giving us an opinion on how wonderful the factory is. Hopefully the factory will get around to sending the ECU updates and workshop manuals to the UK one day? | ||
| Doerman |
Crowley. The ECU updates do not need to be "sent". Your local HD service specialist just have to log on to HD-Net and pull the information as well as the software update. The manual? well, that's another thing. BUT you are not singled out- nobody has them in it's entirety! | ||
| Crowley |
Doerman. The factory 'mouthpiece', Buell UK have 'phoned me and told me there's a problem with getting this information to dealers. Can I assume this official source is lying to me? | ||
| Tasmaniac |
Apparently there is a problem with SPX and the download over here in OZ the info is there but the equipment cant install it. can't get mine done yet. i did get the starter solenoid bolt on done though Brett | ||
| Astro |
hey tasmaniac...im in QLD and my 1125R is going in for a service tomorrow ...is there any other recalls/fix ups that should be done ?? | ||
| Court |
>>>Can I assume this official source is lying to me? Not exactly. More, it sounds like a smoke and mirrors sort of logic to calm the eager masses. The re-flash exists in a series of bits and bytes and travels at about 299 792 458 m / s. There may be other issues and it may take a couple more days (be mindful that the re-flash ACTUALLY hit dealers 4 days after I first reported it would) so be patient, stay in touch with your dealer. . . . and, by the way, don't call people liars. . . . it makes the balance of the conversation difficult. I call the EU tech guys today and if I get any better information I'll report. Look at it this way . . .. if you don't get it for 2 weeks it'll still be 18 months faster than most motorcycle companies could have responded. Court | ||
