it looks like my almost 3 year old yuasa is weakenning. It has difficulties starting the bike at low temperatures (0~2deg) even though it cranks is long enough but not fast enough! From past expereince and 85% battery won't get my bike going! So. I am seriously looking at lithium based batteries and in particular Aliant YLP10. The problem I see is that the connectors are in the middle of the battery and doudt if the battery cables and connectors can reach & fit inside the tight plastic holder. Has anyone fitted one of thesewho can shar his/her wisdom??
