How's it going guys. I have a problem with my 2000 GSXR600 w/ 18K miles. CA model

My bike loses power while riding it because the battery is not getting charged.
On a full charge it'll last a few days but next thing you know the speedo starts
to lose power. Then next thing you know i have to push start my poor baby.

I put a voltimeter on the battery and it reads 12.34 or something volts.
When i start the bike it jumps to 12.75. If i turn the high beams on it drops to 12.22.

I'm almost positive it's the stator/alternator. I swaped in another one from another 600
engine i had laying around and still nothing. I didn't swap the rotor though. (You know the
part that the stator goes into.)
Could that be the problem? Could it be that i have to swap both things out together since
they've been broken in and worn in together? Maybe the original rotor and new (well used)
stator are not making a good contact or something. I don't know.

What is the most common problems like this on these bikes?

Oh BTW to those who are going to ask or tell me, yes i've already tried searching the forum
but i didn't find something specific.

Thanks guys

+1 for Battery

In these forums, you will find a few posts stating that you should expect to see ~13-15v across the battery terminals when the bike is at 5000 rpm.

Are you checking the voltage at idle?

i had my battery tested with a load tester and it tested fine so i really don't think it's the battery although i'll probably end up getting another anyways.

I don't remember if i ever checked the voltage @ 5000rpms. I'll do it tomorrow and let you know. I'm sure i have though.

Any other comments are welcome.

Thanks

Just to let everyone know i fixed my charging system. I dropped my
motor to do a head and cams swap and change a head gasket. In the
process i also changed the wire harness. I believe the problem was in
the harness. I would have sworn my harness was good.

Just to let you guys out there know, that if you run into this problem
check your harness.
