Default Need electrical help

Ok so here's the deal. My battery was dieing all the time last year, this started mabye 5 months after I got the new battery. For mabye 5 more months I continued to charge my battery when it died (about half dozen rides after charged). Finally looked into it and went ahead and replaced my stater, rr, and plug to the rr (rr and plug was fried). The battery still died though so I assumed after continuos abuse of charging up n down it ruined it. Well I just got a new battery after the winter, and sure enough about dozen rides later she's dead again. I don't know what else it could be now that the stator, rr, and rr plug are new... less its a ground wire somewhere off, ect.

I'm on the verge of selling the SOB if I can't figure out how to fix this issue. Help please, thanks a ton!

A quick check you can make to see if your battery is getting a charge, is to start the engine, switch on the headlight, rev the engine and see if the intensity of the headlight increases significantly. Best to do this at night as it will be easier to see the light brighten up. Another check can be with a volt meter set to direct current, connected across the battery terminals. Again rev the engine over 3-4000 revs and see by how much the voltage increases. You should see a rise up to around 13.4 14.2 volts across the battery terminals on your volt meter. If all is well, it shows your alternator is giving out a good charge. If the battery is getting a good charge then something must be draining the battery or there may be a bad earth connection. A good auto electrician should be able to diagnose your problem fairly easily and shouldn't cost that much, but of course that would be your choice to use one. Good luck!

I did try the headlight thing, or moreover simply noticed it and yes it does get brighter. My buddy thinks its a ground wire somewhere loose, frayed, ect.

checking ground is pretty simple, from one end, take a meter and mesure the ohms between the chassis to the neg terminal of the battery, you can check all over the place as it should all be connected together.
but a bad ground wouldnt kill the battery, it will however give you starting issues if thats the problem you are having.
have you checked the actual battery when its 'dead' to see what the voltage is? compared to a full charge? you can also take the battery in to a place that repairs them or even some higher end parts stores and they will put a test load on to see if it can push what it is rated for. something like 10A/hr is what you need for most bikes.
and last thing, start looking at heavey items like lights, horn, aux lights (if you have it) alarm and other junk. that will drain the battery.
one of my friends had two walmart special aux lights on his bike for added visibility and they drained the battery faster than he could charge it with the crappy stators we have on our bikes. swap out the bulbs with LED bulbs and done. or you can look into HID lighs.
bottom line, something is drawing too much juice out of your battery.
