I recently bought a 96 yzf750. it only has 9k miles on it, and after cleaning the carbs it runs and idles well, but the tach keeps going up to 7k on its own...like a code or something. Anyone know what that means? Also, I have to dump the clutch around 4-5k in order to take off, otherwise it just sputters at like 1.5k rpms and then dies when i stop giving it gas. Im assuming thats the exup acting up? When i first turn on the bike, should i be able to hear or see the exup do anything? thank you for your guys time.
