Battery Runs Down

Battery Runs Down
After charging the battery the bike starts up first try, but after running it for awhile the battery runs down and it has issues starting (solenoid clicks but not enough juice to get it to go.) I can bump start the bike and it runs. But eventually it runs down to the point where I can't even get it to bump start. Where should I check for wiring issues? Battery? Alternator?

Regulator/rectifier
Check the charging rate across the battery with a voltmeter at 3000 revs - if it's below 13.5V your r/r is probably cooked or there's a major power drain somewhere.. Easy to fix - 15 minutes and around $100 or take a chance on a secondhand one on fleabay...............
look up Electrex on google - r/rs come with a year's guarantee. I have one - excellent.

Is it a new battery?
Check the voltage while running like Shadow said. If it is low the charging system is at fault.
Test the battery as well. Charge it up and measure the voltage and then leave it for a day. If the voltage reading is way under what it was right after you charged it, your battery is bad.

Okay. The stator is fine, the wiring seems to be fine, the battery is good, the rectifier of the R/R is good (checked the resistance between diodes), but it's still not charging. So I'm guessing it's the regulator portion of the R/R that is shot.
What's the best brand to replace with? RMSTATOR or Electrex?
