I got a free 1998 Kawasaki Mojave 250 with most parts and the engine in pieces. I am planning on putting it together, but I don’t have a battery and I cannot find the battery size for the life of me. I really hope it uses one because I bought a 12V horn to mount on it so I can be loud and obnoxious. Also, is there anywhere I can find performance parts for the engine? I want it to go fast.
