im looking at brutes,grizzlys, and kq but ive heard horrible things about crancking the engine cases and the engines smoking???? can someone give me some insight before i make a purchase? thanks

 

my dad has an 05 kq 700. over abundance of power. its still pullin at 70 when it hits the governer. change the rear tires, stock suck. have had 3500 pound trailer behind it no problem. but it can still keep up pretty good through the open trail will run 55 60 all day long in the trail no prob. runs good jus change the stock filter for a uni and but vasoline between the filter and the airbox to seal it and will run forever.
