falicon makes awesome cranks. but there like a grand? I ran a hot rod in my yfz and plan to put one in the kfx. Ran it with a 13.5:1 piston and had no problems with it. Im sure it would be fine on the kawi. and save your self money. Falicons are good if your running 70hp motors. but a 50-55hp motor u would never need that strong of a crank
