Here's the story:
My bike has been running like shit for about 3 weeks, dying on me every time I leave the school at 9:30pm with what seems like flooding. I let it sit for a long time and it will fire up again.
It would start with the choke on, and run for a while then bog down and die, especially if I touched the throttle.
Anyway, on friday it dropped cylinder #4 some time between when I shut the bike off when I got to school and when I fired it up after school... I dont know how just sitting there can kill a cylinder.
I got it home, took the carbs off and cleaned them thoroughly, the gas tank had brown shit in it so I cleaned it out and did the POR15...
Got the carbs back on nice and clean, gas tank nice and clean and sealed and started it up, yeehaw! I'm running on 2 cylinders now!
So, it dropped another cylinder, now it runs on 3,4 but 1,2 are dead. So #4 is back to life, #3 is still okay but 1,2 took the day off!
Spark is on all 4 cylinders, there's gas in the tank and the carbs are clean what the FUCK is going on?!
