Its a stock 550 ext special...i ride kinda aggressively...when should the clutch engage to get peak performance without worrying about burning down...i know its only a 550 but....it engages around 2500 to 3000.....seems early to me? Any thoughts

Book says 3500 and peek at 8000! So you could replace the drive spring to get it to 3800-4000 and then tighten the driven to get it to 8k!
