Hey guys. I just got this magnum and the rear axle had been swapped out with a sportsman 6×6 (entire thing. Swing arm and all) found a new set of wheels to fit. Since the originals wouldnt. My main question is the quad is quite sluggish but has amazing top end speed. Could this be maybe a difference in gear ratio’s? The belt and clutch are new so I know it’s Not slipping. Also when sitting in neutral the engine runs great but seems sluggish revving. The Carb had Ben rebuilt before I purchased it. I’m just couriouse because I also have a 300ex Honda and revving wise its at red line quick long before the Polaris even thinks about being red lined. Any advise would be helpful. Thank you.
