I got a question for experience motorcycle owners...Just purchase a Yamaha bike cover for my R1 2005. I got a battery charger "Tender junior" 12 volt attach to it for the winter in a non heated garage. It can be cold here in winter and I wanted to leave the battery on the bike because I am starting it every week. I am worried for the bike because of vapors produce while charging the battery (even if it goes in float mode after full charge). The vapors are trapped under the bike cover...Is it safe for the bike , the paint etc..Thanks for your suggestion, J.P.
