Problems with charging system??

Anyone have to replace the stator on their '04 '05 CBR1000RR?  My bikes not charging the battery.  My battery load tested fine and my regulator/rectifyer is ok. 
 
I'm just curious to see if anyone else had this problem as Honda did update the stator for those years, but don't have a recall for them.  So much for Honda reliability.

Try a search. Its a common problem.

Lots of people have needed a stator replacement for the 04' and '05.  Some 06' and '07 models have had trouble too.  If you don't have a bunch of aftermarket lighting or electrical mods on your bike you should be able to get it repaired under the 6 year warranty extension.  Just curious, how where you able to determine the battery and rectifier were OK? 

    there is a sticky on 1000rr.net explaining the stator problem and hondas warranty covering it

might want to give that a read before you go to the dealer so you are armed with the correct info

I used the service manual and followed the testing procedures in the manual with my multimeter.  When the bike was running at 5000rpm and high beam on (as per the manual), the measured voltage should be greater than the battery voltage and less than 15.5v.  My battery was about 12.8v. and was being drained.  I did the same test on my friends ZX-10 and his was at 14v @5000rpm with high beams on. 
 
I asked the service mechanic at Mission Motorsports in Irvine, CA if there were any recalls, but they said no....

My warranty is up, I have about 20K miles on it.

*************************************************

American Honda has determined that the
ACG/charging system (stator and flywheel) on
affected 2004-2005 CBR1000RR models may
overheat and cause a short circuit, resulting in
insufficient battery charging.
To ensure customer satisfaction, American
Honda is extending the warranty an additional
six years for the ACG only.
If a customer complains that the battery of
their 2004-2005 CBR1000RR is not recharging
properly, proceed to the INSPECTION section
of this Service Bulletin.


All 2004-2005 CBR1000RR customers within
the affected VIN range will receive a letter
notifying them of the extended warranty. If
the ACG is malfunctioning, they should take
their motorcycle to a Honda motorcycle
dealer to have the ACG inspected and, if necessary,
replaced.
A copy of the customer letter is reproduced
on page four of this Service Bulletin.

Before you begin the repair procedure, check
to see if the unit has already been repaired.
• If there is a punch mark below the first letter
of the VIN, the unit has been repaired. If
the customer complains of a charging
problem, proceed with normal troubleshooting.
• If there is no punch mark below the first
letter of the VIN, the unit has not been
repaired. Proceed to the INSPECTION section
of this Service Bulletin.
NOTE: This is a warranty extension, NOT a
product update. It is your responsibility to
make sure the VIN is within the seven year
period of the unit’s purchase and delivery
date to the customer.

Thanks 
 
I called Mission Motorsports and he's going to look into it.  I already bought the stator a couple of days ago so I just want to see if I they could just give me the credit for it.

12.8V, that is so bizzare.  When these systems fail, they don't seem to die completely.  Believe it or not, your charging system is still delivering some current.  If the charging system was generating zero power, you'd see 12.0-12.3 volts (assuming you started with a charged battery).

I wouldn't swear to this, but I think the rectifier/regulator can be cause of the toasted stator windings.  It'd be a shame if you put a new stator in, only to have the rectifier/regulator burn it out for you.  If Mission Motorsports is still balking, try calling the number on the attached warranty notice.

I'm an idiot for not checking on the forum before hand.  I found my warranty notice in a pile of paper.  I already replaced the regulator/recifyer and didn't make a difference.  When I tested the battery alone it was 12.8v, but when I started the bike and switched on the high beam the battery started to drain quickly.  I'm going to take it in this week, but I have to put on the factory turn signals back on. 

Thanks for all the help everyone!!!

Hey guys:
 
I had this problem for the 1st time on my '05 Honda 1000RR. Rode for an hour or so, stopped for gas, and then she wouldn't crank. Had to run and drop the clutch to start her. When I got home re-starting wasn't a problem.
It was exactly how the Honda correspondence stated
I did take the battery to Rick Case Honda, and they told me the battery was fine.
 
Guess I will have print the letter and taking it to them.
 
Thanks everyone
 
 
 

FYI,
  There are three posts on here related to the same topic of problems with the charging system.  To keep everyone updated, I opened up an RO# on Sunday and they still haven't received the ACG kit yet....One would think, since they had a warranty extension for this problem, meaning they are aware of it, they would have enough kits at their stadium sized warehouse in Ontario, CA, but....I guess not....Sufficed to say, frustration is really setting in now!!

at 16,ooo miles i got stranded, got it to the dealer. and they said stator and regulator rectifyer was bad. honda replaced stator and stator wheel for free. regulator was fine. HONDA WILL PAY FOR IT!!!!! DONT LET A DEALER TELL YOU OTHERWISE. if they try to blow you off. call honda direct.

I just got my bike back, seems to be charging fine.  It was covered under that extended warranty.  We'll see how long it lasts....
