My battery died while I was driving today so I
bought a new one and got it charged and on
the bike and it died again on my ride home.
Could this be a stater problem and does
anybody know a trick for seeing if a loose wire
is pulling amps from my battery. Any help
would be appreciated. Thanks

First thing,when you buy a new battery it needs to charge at a max of 2 amps over night before putting it in service or it won't last.If you had a loose connection the bike wouldn't start.It sounds like you have a charging problem.If you take your original battery and charge it over night,it should be fine.You need to get the charging system checked to see if the bike is charging properly.

Could you give me a little info on exactly what
the charging system is on these bikes. It does
not an alternator or generator is it just a stater
that keeps the battery charged?

The charging system consists of a stator & a regulator rectifier to keep the battery charged.

Thank you for the info.

What do you mean when you say your battery died while you were riding? The bike started up fine, then it died while you were riding it? How far did you go before it died? How did you know it was a dead battery and not some other problem? Did you try and start it again and did the engine turn over (did the starter motor work)?
Once the bike is running, as in when riding it, it should run with a bad battery too. How do you know you didn't have a loose connection at a battery post or somewhere else in the ignition system?
How did your new battery get charged, ie, for how long and how do you know it was fully charged up? It would not make your bike stop running if it was a new battery even if not fully charged, it may just not start your bike more than a few times 'till it crapped out it if wasn't fully charged first. I don't think your old or your new battery or your stator has anything to do with your bike not running.
Get a voltmeter, measure the battery voltage at rest. It should be 12.6V min for a fully charged battery. Start the bike up, rev it up to at least 2500-3000rpms and while it's there, measure the voltage again at the battery terminals. It should be at least 13 up to 14V, and if in that range, there is nothing wrong with your charging system.
You have some other problem I bet, not your battery. And loose wires do not pull amps from your battery and kill it, they will prevent current from flowing or make an intermittent connection.

Addendum to the previous post.
When you say your battery died, did you also mean your bike died, ie, it stopped running? One possible simple reason having nothing to do with the battery is a plugged gas cap vent causing a vacuum in the tank - that could have caused your symptoms causing the bike to be starved of gas, especially if you were low on gas in the tank. Opening up the gas cap would cause a whooshing sound as air runs into the tank, and then the bike would run fine, 'till it happened again. There are many threads on many other forums about that, probably on here too. If your bike suddenly dies while riding it, open the gas cap and then try to start it again. It can happen at any temperature, sometimes especially when it's hot, then the tank gets cooled by air flow or rain for example.

Found the problem. My stator was bad, replaced
it with one from a wrecked bike and problem solved.
Thanks for the input everybody.
