Hi Chris, There are at least a dozen things that can cause that and half of them take longer to write about than to check, I advise getting a manual they are under $20.00 and will save you a lot of time and headache. Check your original message I believe it got chopped off, it helps to have a little background so we have an idea what the history is, that will let us know where to start with you. It´s a good bike, hang in there. DBW
