The first video definitely looked like a bad battery/contacts causing the display to go off everytime starter tried to turn(tried to draw heavy current from battery). Did you charge the battery for 2-3 hours?
The last video is very surprising to me as I havent seen anybody open the alternator and then try to start the bike. Even if the bike starts up, the gears in the alternator arent properly seated, so they might fly out or something! And opening that cover drains oil meaning more friction, esp in the clutch plates etc. which are right opposite the alt. on the right side of bike.
Please correct me if I'm wrong but I think trying to start the bike with alt. cover off isnt advisable

 

its not... but i was just seeing if it would turn over.. i was seeing if the gears were turning on the inside but clearly they are not... i dunno man im gettin so frustarted errrr

 

Pull your plugs to see if there's enough power in your starting circuit and/or starting motor to spin the engine over. Perhaps the starter motor is dragging.

 

which plugs are you talking about? are you talking about my spark plugs? or connection plugs to what?

 

Sorry - I was talking about the spark plugs. This will cause there to be no engine compression and everything should spin freely provided the starter is still in good shape.

 

spark plugs seem to be good, how do i check my starter?

 

With the spark plugs removed from the cylinder head see if the starter has enough power to turn the engine over.

 

alright

 

alright this time i took my spark plugs out and it turned over.. just oil shot out and scared the **** out of me... lolz i have oil all over my glasses and my shirt! lolz that was funny but do you think my head gasked is messed up or is there a way if you tip the bike over oil seeps into the pistions?

 

If you had excess oil in one of the cylinders there's no way it can be compressed using the starter, thus the engine won't turn over. I'd continue to turn it over w/o the sparkplugs in to ensure that all the oil is out of the cylinder, then I'd reinstall the plugs and see if it can spin the engine over with the starter.

This commonly occurs in the PWC community when a rider "swamps" his watercraft. The first thing they do is remove the plugs and crank the engine over repeatedly. PWC starters are powerful enough that if you try to crank a water logged engine over you risk the chance of bending a connecting rod.

If you did have it on it's side then it's very likely that oil is in the cylinder (the oil would likely be in the cylinder that was closest to the ground when it was tipped over or oil could have pooled in the head and seeped past a valve stem seal.) If it wasn't tipped over I'd suspect a head gasket and/or valve stem seals.

Hope this remedies your problem.
