Recently got a 2007. I rode to the store and when I was leaving, it wouldn't start. Got it jumped, rode it home, and fully charged the battery. Then, did a voltage test on the battery with the following results...
- Everything off: ~12.5V
- Ignition on, engine off: ~11.7V
- Cranking: dipped as low as upper 8V
- Idle: 14.1V
- 5K: 14.5V
From what I've read, the stator and RR seem alright and the battery is on it's way out due to the low cranking voltage. I'm going to replace the battery anyway (no history) but I just want to hone my troubleshooting skills. Can I pin this on the battery?
On a side note, the battery currently in the bike lists 120 CCA whereas the OEM Yuasa is 210. Can a low CCA rating cause problems?
