'03 WR450F hesitates, especially at low RPM

When I give it full throttle my bike hesitates for about 1/4 of a second. It's worse at low RPM's. I've heard it could be the fuel pump or that a jet needs to be changed (from 50 to 90?). Any ideas? Thanks.

try a 40 leak jet with the new boyesen ap cover. works miracles :naughty:
