I'm running a MSD T/L and I only get about one tank of ride time before I need a charge. I'm currently running a pretty cheap battery, it was in the ski when I bought it, a Deka etx9. I need something I can get a days worth of riding out of without having to charge. I was looking at the Antigravity YTX12-24, it costs a small fortune though and I have a buddy who said he's heard some bad things about them. Anyone have any suggestions?
