My stock YTZ10S (8.6Ah) from '05 RR is getting worse during hot starting. Someone has given me a new Yuasa YTX7A-BS which is fit to the battery compartment but the capacity is only 6Ah. Does anyone know what the negative impact is to the bike especially ECU or some other electrical component? It is about 30% lesser than factory recommendation. Has anyone tried this out before? Thanks in advance for sharing.
