I think my battery is toast. My bike sat for a long time this spring w/out being run.I have a hard time estarting when it is cold and have to Kick it becuase the battery dies. Now when I ride, even after it is charged up sometimes the bike won't turn over. It is like there is a flat spot or too much compresion to turn over. I assume the battery doesn't have enought umph to turn it over. Has anybody found a good replacement battery ?
