The Z loves to rev and I think w/ a couple of teeth added to the rear it could stay w/ the Cannibal. Cannibal corners better. The Z's cornering isn't up to Honda standards. The Z doesn't have much down low, but will smoke a 400ex mid to top end. The Cannibal has alot of power everywhere. It sticks in the corners. The Z has plush legs for anything except full out racing. The Cannibal is more harsh, but will take the bigger stuff better. The Cannibal will simply smoke my sold Raptor on a track. Why??? handleing. The Z is gonna be a machine to be reckoned w/ at the track when the bigger bore kits come out and all the suspension goodies. The sea of red is gonna see some yellow on the tracks near the front of the pack. Trying them both at LS, Utah dunes this weekend.
