Im new to Buells so please bar with me. I bought a Buell of of craigslist last night. 09 1125cr with 8,000 mile. It has a few things done to it including a EBR ECM. It was reflashed 500 miles ago. Brought it home it some back rounds everything was fine. Came into town keep dying at a low idle. Around 1500rpms. It will do it cold or hot in gear or out of gear. Thanks for the help. | ||

The main problem with the '09's is the stator. If it hasn't had the upgrade yet (8k miles, so its definitely a possibility) it won't be charging at idle speed and it will shut off. Could also be a reason why it was up for sale. The fix is not cheap, not to scare you. The stator, rotor, and voltage regulator need to be swapped with the appropriate upgrades, as well as the harness "fix" should be removed. Check to see if you are charging. Start the bike and press toggle on the instrument cluster until you see the system voltage. It should never go below 12.3vdc. If it is low, let us know and we will get you a parts list. Few other things: Does turning the handlebars make a difference? Already has EBR ECM so noid is ruled out. Tried cleaning the spark plugs? The ECM can do it for you, just search for the method. If you pull the air box cover you should see a rubber hose sticking up on the right side of the box. That needs to be clear and protruding about 10mm out of the box. Check the oil, there is a very specific method of doing it. If it is too low it will cut the bike off. If it is too high oil will overflow into the intake and give you problems as well. Other than that, congrats on your buy and welcome to BadWeb! You'll love the bike. My 1125 is the best bike I've ever owned.

Try a tps reset. | ||

Rick's electric stator and shindengen voltage regulator been done but idk it thats right. Definitely thank you for the help and telling me how to check those things, going to do it in the morning. Thanks again! | ||
| Thelaststand |
Did the tps manually. Didn't work thanks tho! | ||

Has the rotor been modified or upgraded? That stator won't last very long if the stock rotor is still spinning around it. The stock rotor did not have a means to cool the stator, and therefore burns them up. Just something to check. How about the plugs and stuff I mentioned before? | ||

I recognize this post. Glad you're getting help on here. Sorry I couldn't help more. If you need help with anything I have a shop full of tools. Chris. | ||

Also these bikes will sometimes get broken contacts at the cut off switch that can cause dying. More common with the r model but worth looking at. | ||

^^thats a good addition, and why I asked if turning the handlebars makes a difference. It happened to my bike twice and both times it would run with the bars to the left, and died when turned to the right. | ||
| Hughlysses |
Will it keep running if you give it throttle? If so, it may be a dirty or sticking Idle Air Valve (IAV). | ||
| 1125rcya |
Start simple, look at your air cleaner and then look at your intakes. Are either one dirty/covered in oil? Are there any codes? May be worth looking into your fuel injectors/fuel rail! | ||
| Thelaststand |
I rode it yesterday. Turning the handle bars either way didn't matter. Seems to be running longer at idle before it dies. Oil level was fine and would stay running if I held it at 2000 rpms. Going to start breaking into it tonight or tomorrow for sure. Ill let everyone know what I fine. THANK ALOT EVERYONE! | ||

Starting to sound like the IAC. That hose sticking out of the air box is what leads to it. Start the bike and spray some throttle body cleaner down the hose. Make sure you cover it. It likes to spray back out and will ruin the paint. | ||

Lol, stupid question, did the prior owner put the air filter on backward somehow? That would be an all time D-move. I'm not sure if putting the air filter on backward is even possible. | ||
| Thelaststand |
So I finally got around to messing with it. I sprayed the IAC and turned it over a few times and ran fine in the garage. Then took it across town and back and now its doing the same thing. My voltage was staying about 12. How would I fine if there are codes? I did see when it cut out it said voltage something but that only happen one time. I'm going order spark plugs and oil tonight and do that when it comes in. Should I spray the IAC again? | ||
| Thelaststand |
And there was a little dirt and grime but not much. | ||

12v is low and could be part of it. I'd test the stator (pull seat off and test the connections of the 4 connection plug w/ only 3 wires in it). It wouldn't hurt to spray the IAC again and do another TPS reset. Might also do the spark plug self-clean process too. THe others have given you great info so i'm not sure how much i'm adding. If you do need to do the stator i just did mine and finished a writeup which may help. In stator thread (stator #2 dead...). How's the battery doing if it's only showing 12v? clean terminals and maybe trickle charge it? While riding what voltages is it showing you (second screen with coolant temp and voltage on console)? Welcome and GL! Rob | ||

a) how old is the battery? ( how hard does the starter have to work to start the bike... quick start or many rotations to get her to fire?) b) how tight are the connections to the battery? c) check your grounds ( one under the tail section by the swing arm pivot (follow the battery cable) and there is one up by the head stock d) bad gas...try some Chevron Fuel injector cleaner/Dry Gas/Seafoam e) check fuel pump pressure...the pump is not "on" all the time ...it is "pulsed" by the ECM...if there is a bad ECM connection ( the connector is big with a lot of contacts) and low voltage it could cause the stall hope this helps | ||

Before you give up on the stator, try this. I had my stator warrantied at 2K miles. 21K miles now. The 'fix' was made right after stator was replaced, it helps! http://www.youtube.com/watch?v=nBYEYGJfyBw&feature =youtu.be | ||

T hanks for the help I will try these things tonight. I don't know how old the battery is but when I got it home last night and notices yesterday when driving after a little bit, it almost seems like there is a pulse in power. When I'm in the throttled runs fine but staying at at the same speed with lower rmps acts like its not firing completely. At ideal the rpms bounce before I finally dies. I'm definitely going the spray the throttle body again. It seemed to help and the rpms where not bouncing and stayed at ideal before I took it out.I want to stay thanks again. | ||

I feel like we are having the same issue... I'm going to check my valves , throw in new spark plugs and see what happens. If that does not work , i'm going to try to swap out the ECM , and see what happens. | ||
| Thelaststand |
That sucks, my value were adjusted at 7500 miles. | ||
| Phlegm |
If your power looks like it is pulsing, it might be a loose ground somewhere. Check the frame grounds at the front of the frame and the rear. | ||
| 1125rcya |
When my power was pulsing, it was do to the vr going bad! | ||

I'm also having a similar issue on my CR. Mine only threw the code for Comm Error once, but hasn't done it since. I checked all the grounds and ran through the electrical manual section that basically indicate the ECM. I even pulled off the IAC and cleaned it, but that didn't make much difference. Mine will start up and run at 1800rpm for about 8-12 seconds, and then drop down to about 1200rpm and die like you hit the switch. No issues when running, just at idle at startup. Also, my fans starting running when they shouldn't and not running when they should over the last couple of months. TPS Reset, Handlebar position makes no difference, injector cleaner used, fuel pressure is good, all of the other parameters in diagnostic mode look good. I'm ordering the EBR ECM today and expect that to fix the issue. I've checked all of the other possible issues in the diagnostic manual on mine. | ||

Post up results when you get the ECM , Please! | ||
| Puddlepirate |
Will do. It is supposed to be delivered friday. Keep in mind though, I troubleshot everything in the damn manual to get to that point, even things that weren't directly related. I wasn't thrilled about having to spend the money for something I wasn't 1000% sure about. The bike has been slowly progressively getting worse over the past couple of weeks (been commuting on it every day for the past 3 weeks since my car hasn't arrived in the states yet). It cut off on me this morning at a stoplight for the first time ever, so I'm hoping the ECM will be the fix. | ||

on BMW S1000rr forums we are having some similiar isues know as "Mysterious shut downs" dealers cant help. Its thought to be related to high alcohol conten in fuel confusing the ecm. Try buying fuel without alcohol in it and see if there is a differnce. | ||
| Puddlepirate |
I didn't see a difference between the E10 gas and ethanol free in my case. Since modern engines are designed to be able to use the E10, I wouldnt THINK it should be an issue. There are a few websites out there that list ethanol free gas stations if anybody else wanted to try that out. |
