Now that riding temps are almost 100 degrees, my 2008 Big Bear Chopper Venom negative post connection has came loose twice and left me twice on the road, stranded witout tools. We changed from the stock Interstate to a 330 CCA Drag Specialty after the first occurance. The dealer installed a second ground so I now have one to the frame and one to the motor. The only thing I added previously were the tender connections. Any suggestions? Locktite on battery bolt? Lock washer? Do away with the barrel sleve? Longer bolts? Im stumped...
