Bought my '82 xs a year ago and have put 5000 miles on it. Don't know how old the battery was when I bought it, but I have always kept it on a tender. Last week it reached the point where it wouldn't turn the starter and wouldn't hold a charge. So I replaced it this morning and all is good. But I have a buddy who tells me that if the stator is good that I should be able to disconnect the negative battery cable while the bike is running and it should stay running. Well mine doesn't stay running. Is my stator bad? Also, my kick start works great normally, but when the battery is dead it won't start it. Why?
