My 750 was running great the night before then randomly
It didnt start it was just cranking over an letting out loud
Exhaust pops. Then i cranked it so much that the batt died

Any help?

Thanks , Jon

Usually the pops mean the battery was low when you were trying to start it.

Check all your ground connections. Take them off, clean them, and re-tigthen them.

Charge your battery (Is it an AGM type? If not you'll want to upgrade eventually)

Check and see if it starts.

If it does, sweet.. now run through slim's checklist to see if you have any charging system troubles.

Pops from the exhaust can also be caused by excess fuel in the cylinders when you are trying to start it. Was it still cranking over good when it was popping? Or was it after the battery was getting worn down? You will need a good well charged battery for these bikes to start good.
As Thtanner stated a low battery can cause backfiring when cranking over.
Give it a charge or jump it with a car, make sure the car is NOT running, and see if it still backfires, or starts good and keep us posted.
