Battery or...Stator?

Hey everyone, this seems like a silly question but i really cant think of how to tell, SO here goes:

i had the battery on the bike till about half way through winter and then brought it indoors and put it on the charger and it was acting very strange, like it would say its not connected, then a second later it would be fully charged, then back and forth, but once summer came i put it back in anyway and the bike started up ok, and so i have been riding around a bunch and just this last weekend the bike seems to not want to start up, even after riding a long ways it does not charge up all the way. and sometimes does not have enough juice to start the bike, but my question now is, how can i check to see if its really the battery or if i have a problem with the...stator?(if thats the thing on the bike that charges the battery) what is an easy way to check? thanks all.

P.S. i just ordered the kick start kit, no more roll starting it...

shoot... i knew it would end up being in FAQ, i should have looked harder! thanks for the link!

Check the voltage across the battery at 5 and when revving

It should stay above 13.5V - below this and you have a stator issue or reg/rec problem

to do this test you need a fully charged battery though (above 12.6 with no load ie off the bike)

Check the voltage across the battery at 5

5? why not 5:15 or even 7:30 :thumbsup:

Ok seriously.. I really recommend you follow the WHOLE diagnostic procedure in the FAQ write up.

While I agree with Graham that if you have low voltage at the battery while the motor is turning at 3 k or so,, It could be more then just the Stator.. You may find it's just a burned / corroded plug in the wiring harness (common fault) It may be a internally shorted battery. It may be a bad ground at the motor.. Point is.. electrical diagnostic work is very hard to do if you do not follow a very specific ,pattern of checking.

dunno why i type 5 instead of idle

Brain Fade probably

I agee - you must be methodical in the approcah to finding the porblem. I was just being very general

The guide in the FAQ is very good, and will help you alot

I'll bet money it's your battery bud. I live in edmonton, I see you're from Alberta as well, and had the exact same problem this spring. Bought a new battery from alberta cycle (they're not cheap I know) and haven't had a problem since.

I won't make the mistake of leaving it in -40 again!!!!!

      I've read a lot of threads about this but still haven't found exactly what I'm looking for.  I'm pulling my 2004 DRZ400S out of storage sometime this week and getting it ready for the season.  I live at 9,000 ft, but my first ride of the year is probably going to be at around 5,000 ft.  I was going to pull the 145 main jet I'm running and put in the 150 adjusting the needle from the 2 clip to the 3rd, then re-jet once I got home.  I already have the extended fuel mixture screw in place so I started thinking that I should just run the 150 jet set up and adjust the fuel screw to compensate for the higher elevation where I'll be doing most of my riding.  I will be going down in elevation for rides until late May or June depending on snowfall, but riding on the street when I'm able.  Are there any disadvantages with this?
      I'm new to posting on this forum, so please forgive me if I didn't get the right search words in and there is already a post about this.

      Good Morning,
        Last night I measured my valve clearances for the very first time (I know...) on my DRZ400S.  It's a 2002 and I've owned is since 2011.  I bought it with t's got about 15,000 miles on it and most of it's miles these days are on dirt.
      Intake specs are 0.10-0.20 mm.  Exhaust specs are 0.20-0.30
      My intake valve clearances are in spec, forgot to write them down.  My exhaust valve clearances are between 0.1778 and 0.2032 which is slightly out of spec.  They are no more than 25 microns out of spec.  My question is, do I really need to shim these?  Will this kind of out-of-spec cause performance, mechanical, or other losses?  As far as I can tell, I'd have to buy a whole shim kit which is like $80.  Thanks!

      Currently have a 2000 drz400s work stock suspension. From my understanding this is the worst suspension the drz ever came with without even rebound damping adjustment. Therefore I'm looking for a upgrade. I'm seeing three approaches to take. First being a newer year s model suspension with dampening adjustment. A SM model USD forks and triple tree or some USD forks and triple tree from a rmz. So if you were going to upgrade what direction would you go. I currently ride off-road mostly but I do have some 17s for on road with as well so have to keep that in mind. Thanks
