Well I just learned an expensive lesson. Cold weather ,and my bike was turning over a little sluggish when I hit the starter button, so being the handy guy that I am , I pulled the battery out for a little look see at the acid level. So what that the battery says maintenance free, I do this all the time with my car batteries, you just peel off the tape on top of the batterie, ignore all the warnings, and viola! the caps are right there just waiting to be removed by me. I peeked down inside the cells with my flashlight and I could see the tops of the plates exposed and not covered with acid, so I carefully added water...not too much, and repaced the battery into my bike and plugged it into my battery maintainer for an overnight charge. Job well done, I congratulated myself. The next day I rode my bike to work and back home and was horrified to see that my proffessionaly maintained batterie just puked acid on my left muffler leaving a permanant scar in the chrome. My bike is parked now while I am awaiting delivery of a TRULY sealed AGM batterie that is in the mail as we speak. If you are interested here is the batterie and where I got it. http://www.batterystuff.com/power-sports-battery/sYTX12-BS.html Why is it that I have to learn everything the hard (and expensive) way? My first marriage being the prime example. Keep the shiny side up...Bob.
