Ok so this isn't a mower question, but i just bought a brand new ez go golf cart that has a kawasaki fj400d motor in it. I saw a post earlier about this engine and since noone on any of the golf cart forums know much about them and you guys seem i figured i might try to ask you. What are the limitations on this motor? Such as rpm? If i turn the governor up how far can i go? Till it hits the speed limiter and bounces around or is that too high? Any other tricks to these motors that i can do? Not ready to upgrade to the 35 hp v twin yet. Looking hard at them though! LOL
