I just put on fmf megabomb, powercore 4, dynojet kit and removed the airbox lid and snorkel. my jetting settings are main jet: 128 and "e" clip on the third from the top. With my gas/air screw 2 1/2 turns out.

It started up perfect. And durning my test ride it ran good for about 15 mins of hard riding.

Now the problem. While my test ride it started to die "bog" out on me and when i pulled in the clutch it turned off. It seems to bog in high rev.

HELP ME PLEASE!!!!!
