06 Heritage, starter will spin but bendix won't engadge every time, very intermittent. If it does act up, it is most often when its cold. I had the bendix replaced. That seemed to be the fix at first, but no, its still there. I dont know what throws the bendix in. Is the starter turning too slow or is there a solinoid that pokes the it in? I looked through the self help tips and only came up with the bendix replacement. Any other tips someone knows of would be greatly appreciated.
