2010 Level 1, 70k miles, 1 owner, Pearl Hot Rod Yeller (of course). Looking to replace the battery. From all that I read, it seems that Yuasa is the battery I need; but which one?? Specs are slightly different between the GYZ20L (210 cca), YTX20HL (310 cca), and YTX20L (270 cca). Which one is the better battery to use? Thanks!!
