New to this forum so please bear with me. I have two CF Motos cforce 500s, and one has a re-occurring issue with the
EFI light on the dash. Put the key turn to 1st position  and slide the Red switch to on and the efi light Flashes and Machine doesnt start! Battery is full charge. let it sit and try again and sometimes it starts and other times it wont. Suspecting the issue might be the fuel pump.
