its a stupid setup that is begging for overheating issues. i'll find you some pics.
.....googling....
alright, if you look at this picture i'll post below, you will see an aluminum cover on the side of the motor that is branded kawasaki? the carb is right under that. the air filter on top of the motor is where air is drawn in. then it gets sucked through the entire engine cover and then eventually gets sucked into the carbs. i'll also post a picture with these covers off.
