Our Muscle 117″ Kit for the M-8 platform creates phenomenal power in a bolt-on top end and cam kit! We precision-bore and hone your cylinders to accept our +6cc domed pistons and then CNC-port your heads for increased flow and minimize 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. We offer this kit with 2 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 – this is what we call the “rowdy” choice. The 548 creates tire-shredding power from just about any part-throttle RPM. Great for rowdy riders wanting instant power that are channeling their hooligan spirit animal! The High Power kit (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 max available power. Both cams have a very lopey sound & feel–no hiding that this is a not stock engine!
These kits include gaskets, tappet cuffs and a set of Quickee pushrods with covers to simplify reassembly. An EFI tuner, performance exhaust, oversize throttle body, injectors-intake will be required to achieve results shown
