Okay here goes. I have a 2008 1125R with the "good" stator. Problem is that I have power loss at low RPM unless I'm connected to a battery tender before riding. I get bad throttle response until around 6000 and then whoa... hold on. So, would the Mosfet VR upgrade help this issue by reducing voltage drop? Any other solutions? I know that 09 model owners are having stator rewinds done. Should I consider a rewind? | ||

Go into diagnostic mode with the bike off, check that your TPS percentage is 2% when you have no throttle input, and it smoothly goes to 100% as you slowly open it up all the way. If your bike does not hit 100%, you need a TPS reset or something is binding your throttle cables. | ||

789 - I bet you have the same issue I just dealt with (2008 1125R with 5800 miles). I had very low charging output, so that the battery would drain in just 20-30 minutes of riding with high beams on. Looking at the battery voltage in diagnostic mode, it would get down below 11 volts, instead of being at 13-14 V idling as it should be. Eventually the low voltage warning light (battery symbol) would illuminate. The symptom of this low voltage was that the throttle position sensor would get a (growing) dead zone coming off of idle. As you twisted the throttle, you would get nothing, nothing..... BOOM! The transition point would grow from 5%, then 10%, up to 30-40% throttle as the voltage continued to drop. If you weren't ready for it, it was quite scary going from zero to 40% throttle instantly. While 2008 models don't have the reputation for stator problems of the 2009 bikes, it felt to me as if one of the 3 stator legs may have failed. Turning off the high beams would allow the bike to re-charge the battery in 20 minutes or so and the throttle dead-zone symptom would disappear. A few weeks ago, the charaging system died (almost) completely, and I limped the bike into the dealer. They replaced the stator, rotor, and voltage regulator under warrantee (2 months left). Now, the bike idles at 13-14 volts even with high beams and fans on. We'll see how long it lasts! | ||

Here is a pic of the stator they replaced. I didn't see any obvious signs of damage/melting, but perhaps some of the more experienced people here can. Also, the VR that was replaced looked perfect - no signs of overheating or other damage.  | ||

So they couldn't be arsed to actually diagnose the fault and just swapped eveything out...Not sure I'd bother visiting them if I wanted to actually get to the bottom of a problem, but on the other hand I guess it's nice to have new pieces just before the warranty is up. Still sounds a bit lazy to me.. | ||

I just saw a bad stator that was removed from an 09 and it looked like part of it had been in a fire. Yours looks good by comparison | ||

That makes sense. I never really thought about the "why," but I did notice my bike got increasingly unhappy and easy to stall out if I let the voltage drop below about 12.0V. If it got down to 11.8 or so idling, I'd often end up stalling it out trying to take off. I learned to just bump the revs a bit and keep my high beams off.  | ||

That stator is as good as new. Bad stators look bad, smell bad and taste bad. Wish I could have your old stator for a spare... Z | ||

+1 xnoahx and Zac, that is a great looking stator ? what is the black round thing in the pic? looks like the head off a rubber mallet? | ||
| Jcjohnson33 |
I think that would be the puck. It's just scared up. | ||

Now, the bike idles at 13-14 volts even with high beams and fans on. That's good to hear. Well, that sounds like what my bike is doing. I'll have to check the voltage when I ride. I put mine on the battery tender for an hour and it went green. Went for a ride and things ran fine. I still may spring for one of those fancy voltage regulators though. | ||

I asked to keep the take-offs (thought I might need to pre-order a Custom Rewind), but the service guy said they had to keep any warrantee take-offs in case the factory requested them back. | ||

If your bike does not hit 100%, you need a TPS reset or something is binding your throttle cables. Yeah, I think its a stator/voltage related problem. I did have one time though riding when I started hearing a noise. It was a whirring intake noise like a turbo sound. It started getting louder, I cruised into the gas station, shut off the bike, checked things out, started it up and it ran fine. I think it may have been that noid thingy closing my intake butterflys while I was trying to drive. Whats the deal with that thing? I have an Erik Buell Racing ECU now but should I still take that thing out? | ||
| Syonyk |
The race ECU will never trigger that thing, so it's just dead weight up high. May as well take it out... | ||

sorry guys, I own a october 2008 CR, do I have the good stator? | ||
| Zac4mac |
26.7k miles on mine(2008) and ZERO electrical issues. HID lo-beams, 35w, and heated grips, used often, LED(XBLights) taillight, original rotor/stator/RR, battery, 09 IC since Oct09. Yes, you have the "good" charging system. Z | ||
| Froggy |
No 1125CR has the good stator. | ||
| Zac4mac |
Ooooh my bust, nice catch Frank. All I saw was 2008. A CR BUILT in 2008 is a 2009MY and has the "Problem" stator/rotor set. Z | ||

that's not nice at all. I can't understand if this is a official recall or not. My dealer never told me nothing about this. I obviously knew about the issue (the 2 years warranty is now ended), and I asked if there was a electrical recall scheduled for my bike, but the answer was no. What's the cost of the recall outside the warranty? | ||
| Jcjohnson33 |
An official recall even outside of warranty is provided free as per law and regulations. The only thing is I have checked with the NHTSA and they don't list any official recalls for the '08-10 1125r. | ||
| Froggy |
There was no recall. If you are referring to the harness and relay for the stator, it was an optional product program. | ||
| Zac4mac |
Buell(HD?) did two types of recalls - product campaign and Safety campaign. Product campaign has a time limit, Safety does not. A run of your VIN thru HDnet(@dealer) will tell recalls involved and status. PM me your VIN and I'll run it for you. Zack | ||

Thank you Zac! I'll PM you ASAP. but probably next monday, here in Italy we have our annual buell on track week end! I'll post some pics next week. |
