I've had it for ten years and i'm at least the third owner and it has alway started and run fine. I'm not overly technical, but it obviously doesn't need a battery. The first thing i removed all the useless stuff like the headlite tail light, speedo etc. Now it's sleek and mean and ready for the Baja 500... This horse will go about 385 lbs. so don't let it fall on your leg.... It has the same carb as my Honda 90..
