I am buying a new battery for my 95 gs500e. I was looking at ordering one from online, and the site I am ordering from says it is factory gel sealed and activated. Does this mean that I will not have to charge it once it arrives? Secondly, the tachometer and speedometer are both not working on the bike randomly. I bought 2 new cables but have not put them on yet. My question about this is that the mileage on the bike is not working either, which is located central to the tachometer - if I fix the tachometer, will the mileage most likely start working again? Mechanically driven.
