i have a 1983 kawasaki gpz 1100 with 16,000 original miles on it i havent started it since last june well the battery was dead so i bought a new old hooked it up and it started right away no starting fluid nothing but the engine is making a really loud whistling noise that wasnt there before any help with this would be great its whistles at idle and when i rode it i put about 20 miles on and figured i better find out what this noise is i can tell its coming from the motor just no idea what it could be
