A lax local controller reported an airborne conflict between a helicopter at 1;500 feet transiting north bound on the sepulveda route and an air carrier aircraft at 1;400 feet landing runway 25L. The air carrier captain also described his crew's actions during the go-around.

Narrative:
Arriving at lax on the SEAVU2 arrival; ATC gave several speed assignments that were a bit aggressive. Crew was a little late slowing to approach speed and passed 1;000 feet at reference +20 with idle power. A go around was performed.with aircraft being vectored on a close in downwind for another approach; ATC gave a quick turn to downwind and visual approach clearance 3 miles outside the limma ILS 25L final approach fix; with a request to maintain 180 KTS until limma. The crew descended and intercepted the localizer and glide slope just before the fix.at 1;000 feet; with the autopilot engaged and aircraft on localizer and glideslope; speed was + 15 with idle power. At 800 feet; speed was at vapp and engines spooled; everything stable. Captain decided to continue for the following reason. A normal landing was guaranteed at that point and a second go around would have used up remaining buffer fuel. Any unforeseen problems prior to or during the third approach would definitely have put things in the yellow.crew was late slowing to vapp leading to an unstable approach at 1;000 feet.greater attention to reaching 1;000 feet with aircraft fully stabilized.
