You installed a New fully charged battery. You leave the bike alone for a few days and when you try to start it, you find the New Battery is fully drained to Zero. (checked with a voltmeter)

Is that what happens?
 
And these new batteries are properly being charged up before install??
 
My sporty did the same thing. you didn't say what year, mine on an 07. don't know if this is your problem or not, but mine would loose charge over night. everything would work ok with new battery, but if it set over night it would loose charge. we checked everything and found nothing bad, (fuses, ect). the cause of the problem was corrision on the connections. we removed all connections and cleaned really well, added di-electric grease and replaced. now everything is fine. it took a while but it solved my problem. we even cleaned the connectors for each fuse, and where each wire connects. put star washers on everything that we thought needed them.
