These Teryx/Brute Force Big Bore Kits offer the engine builder an easy way to gain horsepower and torque.

Unlike other kits on the market, the Muzzy kits include the cylinders already bored and plated. When purchasing the 840 and 916 bored cylinder kits, you pay a cylinder core charge at the time of shipment. A refund is issued as soon as we receive your qualifying cores.

(These kits fit the Kawasaki Teryx, Brute Force, & KFX-700 - Call for details)

There are no core charges for the billet cylinder 916 kit. 999cc can be achieved when adding the Crank and Rods kit.

All kits include nickel silicon carbide composite coated front and rear cylinders, Muzzy pistons, rings, pins, clips and gaskets.
