Zipper’s Performance Muscle 117 for Milwaukee-Eight

Power Play

Zipper’s Performance has you covered to add muscle and get your Milwaukee-Eight engine into shape for the new year but getting rid of that gut you put on from all that eggnog and pumpkin spice is your problem.
Their Muscle 117″ Kit for the M-8 platform creates great power in a bolt-on top end and cam kit. Zipper’s precision-bores and hones your cylinders to accept the company’s +6cc domed pistons and then CNC-ports your heads for increased flow and minimized intake to exhaust port differential. Oversize valves and performance valve springs are installed on carefully machined heads that are key to making this big M-8 power. They offer this kit with two cam choices, both of which deliver excellent power curves that are sure to satisfy any aggressive rider.

The High Torque kit includes a Red Shift 548 cam that creates tire-shredding power from just about any part-throttle RPM. That’s great for rowdy riders wanting instant power that are channeling their inner hooligan.
The High Power kit version (Red Shift 552) builds power with an extra-strong mid-range and top end pull. This is the one for power junkies who regularly run in higher RPM ranges and want maximum available power. Both cams have a very lopey sound and feel. Good luck trying to be stealthy with it…
