Ok I have been through the stator pages and my bike doesnt charge over 14.8 at any rpm but after about 180 miles, I am finding my battery cells almost dry. The battery is only 3 months old so does anyone have any clues. I assumed it was overcharging and boiling off, but that does not seem to be the case.

As to your battery, there are only two ways for the fluid to get that low:
1. Boiling off
2. Crack in the case
Either way, you've got acid coming out. Any signs of acid damage to the frame?1978 GS 1000 (since new)

yea, there is acid on the frame, but it only loses acid after a long run, not when sitting. but as I said, It is not overcharging at 5000 rpm. I am at a ??????Comment

Can you mount a voltmeter on it and go for a ride?
Might be something happening that you can't duplicate in the driveway.

What does your V meter read with the bike turned off ? Slight meter error and you could be around 15 volts which could cause slight over charge a loss of water in the battery. Even tho it is new it could be the battery too! I have had batteries that used various amounts of water for no apparent reasonComment
