Hey, Cdberent, welcome to GC !
From what you describe in your post the bike starts fine after a good charge but if you leave for a period of time it will not. The problem persists even with a new battery installed. In that case you may have something that drains your battery. What accessories you have installed? Are any of them powered all the time even when your ignition key is off?
If you own a multimeter:
With the key in the off position make sure you have 0.00 A current flow at the battery terminals. There should be a thread on here with the exact problem, I'll try and find it later.
And with those new batteries be aware that discharging them bellow a certain point will damage them. Post back with what you found. Good luck!
