got bored today after picking up a bunch of free stuff including 2 lawn tractors and a 1984 kawasaki ninja gpz900. anyways one of the tractors had a straight axle with diff on and a sprocket so i made some brackets and bolted the axle up to a chopped up speedway frame that i got. heres how it sits now still got to put the motor on it figure out some kind of brakes for it . it will be powered by an 8hp briggs motor flathead. any ideas for brakes? i was thinking of using one of the hydraulic master and caliper on the sprocket or mounting a rotor from the motorcycle on the other end of the diff housing.
