I'm having trouble keeping my 12r running. it'll start just fine, but after about 5 seconds of nice steady idle, the rpm's start to oscillate and it dies. I reset the ecm, nothing. I put in new spark plugs and wires (needed the wires), nothing. played with the idle, it'll run if I set the idle to 2k, drop it below 1400, dies... this all started after I lost the ground to my TFI. had to fight with her to get home, but I made it. Fixed the grounding problem, but now I can't keep her going. Ideas? | ||

Check charging system... my charging system died last week. It would start (if battery was charged) and would run only if kept above idle. RPM's wouldn't stay stable, if I tried to hold it at 3k it would vary by up to 500 rpms randomly. She didn't run well either, obviously... would accelerate fine for a second, then cut out, then back to normal. This might not be your problem, but I guess it wouldn't hurt to break out the service manual and check to make sure. Best of Luck | ||

Ok, i've done some more investigating and here are the symptoms. idle surge whether warmed up or cold. more so when the bike is cold. I just took the TFI off (race ecm only now) and the bike will hesitate bad at 4k rpms After I punch it and come off the throttle, the engine will idle at 2k rpms ( clutch in) I have a lot more deccel popping now No check engine light or anything... HELP, PLEASE! | ||

Been doing some reading and was curious what a stator was, what it does, and what happens when it goes out. | ||

Voltage goes to no more than 12V (battery voltage) and maybe significantly less. Also the system will not maintain 14.3V and the battery will not charge. | ||
| Aeroe |
So....it's the meat and 'taters of the alternator? | ||

Yes, the stator is the stationary part of generator, the thing with a bunch of copper windings on it that fails and needs replaced if you run it in GL-5 gear oil too long. When it fails, your charging system no longer works and your battery will soon be dead. | ||

Correct - just got my bike back last night from the dealer from getting the Regulator/Stator/Battery replaced under warranty. Good side- I no longer need to change the primary fluid. | ||
| Aeroe |
OK, so if my stator IS bad...how long do I have before my battery runs out. Because I've ridden her for 15+ miles... | ||

When my stator died I was riding to work. Started it up and 16-17 miles later it died. When the engine light comes on you have 30 seconds to 5 minutes to find a good place to pull over. American Sportbike has a volt gauge I am going to install before I ride mine again. | ||

Well, I don't think it's the stator. I've ridden it for awhile and haven't seen any sign of a weak battery. The symptoms are pretty consistent. Curious...will the bike run with the ECM unplugged or broken in anyway? | ||
| Daves |
no, your bike will not run without the ecm. Have you adjusted the idle correctly? Have you reset your TPS? Check battery terminal connections? | ||

Not sure, but will these run like my GSX-R trackbike by just charging the battery every night? It will run for a good 2-3 hours on one charge and is usually good for a whole trackday. |
