Question about 2003 Aprilia Atlantic 500
The EFI should come on for about 5 seconds. If it stays on, you are about to lose the rectifier, battery and halogen headlight. When the EFI light stays on, it's telling you that the rectifier is failing. If you continue to oiperate the bike, it WILL quit. It will cook the battery and leave you stranded.

If this is a 500 then it's using the Piaggio x9500 engine, it's fuel injected, efi is 'electronic fuel injection'
that light must be a warning that one of the sensors is playing up, aire temp, air flow, throttle postion etc. take it to an Aprilia dealer, they have a test box they plug in to the wiring and it tells you what is at fault. Piaagio dealer might be able to check it as well, they use a device called a texa navigator, could save you a load of grief. biggest problem with the x9500's was under the footboard, the main control box (ecu) has one big block connector for the wiring, this got full of water spray and corroded badly. if the dealer's test box comes up with multiple faults, it's probably that connector which makes false reading, says everything is knackered.
