Headlight circuit drains battery

Okay so my 99’ yamaha R6 runs great and the battery charges fine IF the headlights are turned off. If i drive with my headlights on, the battery drains in like 30mins, any ideas?

Before jumping to the most extreme conclusions...

What are you voltages reading at the various RPM ranges?

Have you had the battery tested?

Yeah, the battery charge reads 14,5 volts @ 5k rpm, had a mechanic double check it and he said there was no problem with the charging system, havent tested the battery but its new so i suppose it should be fine, but how do i test it anyway?

Also about a year ago the stator burned so i replaced it along with a new regulator

I used to use philips x-treme ultinon led bulbs that came with a transformer for each bulb, think they were rated at 25-ish watts, i thought they were the problem so i reinstalled the old 55w halogen bulbs, but that diddent help. Also the blinkers are close to non-exsistant when headlights are on
