Have read a bit and am thouroughly confused. I’m looking to get a bit more clutch grab for riding new england trails, but really don’t want to pony up for a complete clutch kit. Read that springs can help? Put some stock size mud tires on and feel like I lost a bit, and since most of riding is low to moderate speeds, I would like the clutch to pick up sooner and harder. Also, do mufflers and air filters help the 500’s at all? Thanks!
