Sounds like you got the spark issue taken care of so then that leaves fuel.
My Kawasaki bogs a little bit until it's warmed up. Have you let it warm up fully before giving it full throttle?
I usually gradually increase the throttle until it gets to WOT and runs without bogging. Then it's warmed up.
