I'm have a challenge with the battery replacement for an R1. I purchased a Duraboost brand CTZ10S battery from Cycle Gear. The battery consistently measures 13 - 14+ volts when fully charged yet still struggles to turn the engine over. Specifications advertise CCA's of 130. The Yuasa brand YTZ10s advertises 190 CCA's. Could the brand or the CCA's be the reason for the poor performance of the battery?
