This is the New Ninja JX21-B05 Off-Road Buggy Engine. The innovative JX21-B05 is completely NEW. The B05 features a 3-port long-stroke design that offers smooth low-end power and exceptional mid to top-end power. The crankcase, backplate and carburetor feature a new design. The new DLC-coated crankshaft is silicone filled and has two tungsten counterweights for smooth rotation and better balancing. The new fuel-efficient 22E carburetor is easy to tune and provides great throttle response and smooth acceleration. The B05 comes with a lightweight cooling head to provide exceptional cooling and stable operating temperatures. An o-ring between the cooling head and the combustion camber creates a better seal and reduces vibration.
