F1 Error code 65

[Diablo6v]

Changed my spark plugs and put everything back together. Bike starts backfires and comes up with an F1 error code 65. Anyone know what that is? I can't find it anywhere. I didn't touch any of the battery grounds didn't even disconnect it. So its not the battery or the ground needing to be cleaned.

– If the oil control solenoid valve fails, valve is

65 wouldn't/shouldn't cause a backfire I reckon.  Do you the have coil connectors in correct order? 

Are sure it's not 64?
