During the summer I ride to much for that to happen. During the winter she's usually on a tender. When I forget to put the tender on the battery does drain. My 07 had a PCIII and the 08 has a PCV so I don't expect that to change. Other than the PC I don't know what could be causing that much of a drain.
Thanks for the reply iam heading down the country at the weekend on my 96xjr 1200 costom with new battery I will leave it there so i can bring the jacket home to Kildare we will see what happens then 👍 from Ireland
