from 25 years of experience i would say the head gasket has gone,the compressed air from the cylinder passes via the damaged part of the gasket and pressurises the cooling system and raises the volume in it causing the excess coolant to blow out of the coolant bottle.Thats a real answer from a real mechanic unlike greg who just copies and pastes take it to a shop.

i would say that a selector fork is bent ,will it not go into 4,5,6 gears?

DO YOU HAVE GAS? DO YOU HAVE POWER? TAKE OUT THE SPARK PLUG, RECONNECT IT TO THE CABLE AND LAY IT ON THE MOTOR, NOW TRY TO START THE MOTOR WATCHING IF YOU CAN SEE A SPARK. NO SPARK NO POWER. YOU MAY FIND OUT THAT POWER IS GETTING TO THE STARTER COIL BUT NOT TO THE PLUG. REPLACE THE COIL.

THERE MAY BE MORE TO IT. UNSCREW THE SPARK PLUG, RECONNECT IT TO THE IGNITION CABLE, GO THROUGH THE START PROCEDURE AND SEE IF THERE IS A SPRK ON THE PLUG LAYING ON THE THE MOTOR. IF THERE IS NO SPARK, YOUR IGNITION COIL MAY BE BAD.

If you're battery's dead -- won't hold a charge ... replace it with a new one. Otherwise,y ou'll have more problems than just a code. The code should reset once the battery is performing properly. When storing a bike for a cold winter, remove the battery and keep it on a trickle charger indoors.
