New from Elkridge, Maryland based performance specialist Zipper's, this Sport 107" kit for 2007-up Big Twins is said to deliver "a strong low and mid-range power boost."
Described as "perfect for the rider who wants a total package without busting the budget" the kit includes CNC headwork, cylinders fitted with 107" flat-top pistons, Red Shift cams, tensioners, pushrods, gaskets and a pre-mapped ThunderMax AutoTune system - so no dyno tuning is required."
Zipper's say it delivers 118 ft/lbs of torque and that it reaches 110 hp with the factory throttle body and injectors - "arm-stretching acceleration with the excellent manners and durability that is a Zipper’s trademark."
