I might be wrong but it looks like you got to unbolt the whole battery case.
Maybe with someone who has done it can jump in.

ok figured out the battery cover, put in a new battery drove all day(like 5 or 6 hours) started everytime i stopped, then all of a sudden the bike is constantly backfireing,i dont know why or what would cause that, help please on that, then when got home after riding put a multimeter on the battery to see if everything was ok...nope battery read 11.94 so its still not charging the battery, i always thought if the alternator doesnt work wouldnt the bike die after the battery was drained?

I was just reading something, not sure if its true or not, could a weak battery cause backfireing? I only ask because i rode for like 4 hours with no issues, then it just started to backfire

Low voltage will cause back firing. Have you purchased a service manual? You will need to re-charge the new battery. Test the battery with a multi-meter. A healthy battery will have a reading of 12.5-12.8 volts. With the engine running at 2000-3000 rpm, you should have 14-15 volts at the battery. If it's less test the stator with the following procedure. At the voltage regulator is a round 2 prong plug connector, remove the locking collar and unplug the stator. Set your voltage meter to AC volts. Start the engine. Holding the stator side of the plug, insert the probes into each side of the socket. With the engine at 2000 rpm the meter should read 38-52 volts AC. If the voltage is less you will need to replace the stator. If the voltage is in the appropriate range, then the voltage regulator could be the problem. If you have to replace the stator, DO NOT use a stock replacement from your dealer. Cycle electric makes a very good replacement for around $100.

Most people replace the regulator because it is easy to access. 90% of the time it's the stator that has failed. Buy a service manual it will save you a lot of grief. The HD manual is the best but expensive, Clymer is a good affordable alternative.

Hey slipvayne9278 did you try the test as wraith had suggested?
When it comes to electrical crap, you don't want to *****-nilly replace parts bcuz sometimes something's can be as cheap as a loose connection. When I was a young fry , I once replaced a battery and alternator on a car and in the end it was a bad ground cable that fried on the inside.
