I have a 93 polaris xlt special 580cc, anyways ever since I bought the sled 3 years ago it always had kinda a bog just off idle, it idles at 2500 rpm, it runs great past that certain area where it bogs a bit, I cleaned the carbs, they werent dirty at all, the air cleaner is nice and clean also,the sled is completely stock, so My question is how do I make the sled more responsive?
