Welcome to the Forum...!!
Make sure the Battery is fully charged..12.8v standard...
Check if the decompression spring on the exhaust cam is there or has fallen off...?

For this I need to take off the tappet cover first right?
Yes...remove the tank & valve cover...If it's found to have fallen off, you'll have to remove the stator cover to fish the spring out...

If the spring is off will the engine start al all? Because if you runn start the bike it starts.

No, the starter isn't powerful enough & you could damage your starter with full compression
