I have a 99 RMK 700 mod sled.. It has a U cooler.. My question is: Does the front cooler NEED to be run or can it bypassed because the U-cooler runs the entire length of the tunnel and should keep it much cooler than the stock rear cooler? I have never ran a U-Cooler so I really dont know if it will be cooled enough with just that.. Anyone know on this??
