TBH i dont think this is battery.
i believe this is no spark or fuel supply.
check plugs make sure they are all connected.
check HT's are all ok.
CHECK COIL
check the dizzy is ok.
also u can test by turn the ignition to the second stage (not trying to turn over) and listen for a clicking fuel pump kick in. you can then verify the pump is working ok..
AND DONT DO A DAN. make sure there is petrol in the tank.
it is NOT the battery IMO
