Te310r Flywheel

I have a 2013 te310r that died suddenly last weekend. Right now I suspect the flywheel key could have sheared.
Last year when changing my starter gears I reassembled the flywheel using loctite 620. Now I just tore the threads out of my flywheel puller trying to get it off even though I applied some heat with a propane torch. Is there any method of verifying the flywheel is in proper position without actually removing it? It would be a shame to get this off only to find out everything is ok. The bike still sparks I just dont know if it occurs at the correct time.
