Well my bro was riding it and it cut off outta no where and doesnt work anymore. Ive cleaned air filter and made sure all electrical connections were good. Also there are 2 tubes coming out of the place where the fuel tank hooks up that arnt hooked up to anything is this right. One of these leaks gas when you try to kickstart it. Any help would be appreciated since its my friends bike and i dont wana have to pay for it to get fixed.
