Dual-cam motor: intake and exhaust cams sold together. Our main goal was to design a torque cam that would increase the bottom end and mid-range power to provide instant throttle response and increased power where you need it for GNCC, SX, or Off-Road riding.
Used as a set 4235-2IN and 4236-2EX provide the best peak torque and a good overall power band. Stock valve springs are OK.
