My brother and I finally found the problem. The ground wire was broken but still attached to the terminal so we never thought of that but thanks anyways.
Another question, does anybody knows if a 130 rear tire would fit on the stock swing arm? I'm currently running a 17'' rear wheel. A 2.50 to be exact and would like a little bit more tire and no, I'm not the kind of guy that needs the widest tire but I think anything below 110 tire looks like a bicycle tire.
