I just replaced my stock battery with an Interstate battery that has had amazing results. The stock number is YTX14HBS. It has 240 cold cranking amps which spins the engine quite fast even when hot. The dimensions are exactly the same as the battery that I replaced. It weighs 11.2 lbs with the acid in it. I was told the h in the stock number stands for heavy duty. It made a big difference. Mark.
