I took the sled up to the mountains today and it ran pretty good. When we first started the sled up it ran really good no bog idled great. About and hour or so into the ride it started to bog if you pin it from low rpms to about 6000 rpms. It sputters and really doesn't want to go unless you let up and let it slowly get to 6000 them you can pin it and away you go. If your trail riding or weaving in and out of trees and just barely hitting the throttle it's pretty snappy, but you can't pin it from a dead stop and expect it to get on the pipes and take off it sputters until 6000 and takes up hard. So I guess my question is is there something I adjust on the carbs so it doesn't bog from a dead stop to 8500 + rpms?
