Ok, I bought my 07 r6 back in Sept of 07. In April I had my hotbodies undertail kit installed. After getting my bike home, I had let the fan run to let it cool down and when I went to start it the battery had died. I jumped it and took it back to the shop and they said it was fine. Now, in the past two weeks it has died on me twice and twice I had to search for the nearest hill to bump start it (which was rather easy to bump). Is my battery just shot and can I recharge it with a tender?
