I just got my 05 WR 450 running after sitting for months (ran fine when I parked it). Ive only started it twice, and let it run for a short period of time. The second time I started it (last night) it was idling fine for about 45 seconds. When i went to give it a few revs the headlight died (after market baja design 8" off-road racing light) as well as the taillight. Within a few seconds the engine died too. When I went to kick it over (no easy button on it right now) the light would even flicker like it normally does, and it def didn't want to start... Any ideas what the problem could be? Or where I should start? Any help would be really appreciated.
