Ok, I'm still having problems getting a good charge into the battery on my bike, even after trying several different 'fixes' common to VFR's.

When the bike is cold, I get 12.4-12.7V at idle, and holding a steady 4500-5000rpm, the battery voltage slowly creeps up to 13.5V.
As the bike warms up, the battery voltage is only able to creep up to 13.23V, which hardly charges the battery.
Cruising at 5,000rpm, with the high beam on, the battery voltage drops to 12.7-12.8V.
When coming to a stop after cruising for extended periods with 13.2-13.5V going into the battery, the voltage will drop off we 12.4-12.8V.

Tests/'fixes' so far:
- On my third battery
- Two regulators tried (neither gets really warm after 5min with high beams on at idle)
- Both R/R's will not exceed ~14.2V if attached to a battery NOT in the bike (even the bike battery).
- Sensor wire shorted/bridged to +ve output from regulator.
- No significant voltage drops between the R/R and the battery. (<0.1V)
- Stator resistance is 0.25ohm across each of the three phases, and no continuity to ground with 250V. Standard is 0.1-1.0ohm.
- Stator output it 40V/AC at 5,000rpm (unloaded, should be 50V/AC)
- Stator output is ~3-4A/AC at idle, and exceeds 10A (limit of meter) with some more revs.
- Shorting a light globe across the stator ouput lights it up brilliantly.
- Have run additional 50A wiring from the regulator to the battery terminal/ground.

There's probably a couple of more things I can't think of at the moment.

I'm open to almost ANY suggestions as to what it might be...
HELP!!!
