could be a engine,starter motor or a battery issue.
You need to isolate the fault.
If you are confident the battery is good the starter motor could be pulling too much current and pulling the battery down under load.
First dose the engine run ok when you can get it running if so its unlikely to be an engine problem.
What I would do is get a second battery and wire the ignition from the second battery and just use the bike battery to crank the engine and see what you get. If it starts and runs ok its a battery or starter issue if its the same its an engine issue.good luck.
