Didn't someone post a site that had different noises our motors made when stuff was wrong? Just when I think I've got everything fixed, I've got a noticable noise (I don't think its valves... its not a "clack"). This is more like a loud whistling noise when you put it under gradual throttle... almost sounds like a turbo (I wish!) spooling up. Other than the noise the bike runs great...? Could it be the speedo cable??
