Default Yamaha 1987 FZ 750

Yamaha 1987 FZ 750 possible ignition problems. runs great when it is cold. when it warms up the bike developes a mid throttle bog. the carbs,charging system and plugs have been replaced or rebuilt by a quality yamaha mech. the clymer book says the chances are greater that it is a ignition problem. the bike has less than 27000 KMS and runs vary fast. but its hard to drive at low RPMS. Any insite would be greatful.
