i have a 04 banshee and i just got down with it and it was fine for about an hour. then the bike didn't even want to rev up anymore it just pops out the pipes and has no power at all but starts right up.
i am 570ft above sea level

vf3 reeds
2 into 1 air filter
cool heads 21cc domes

i don't know if it was my jetting because it was running fine.i did notice that i have a little cut in the boot below the boost bottle and i also did melt a few wires but nothing to bad
PLEASE HELP
