Irregular starting

Postby rampantdragon » Sun Jul 07, 2013 3:19 pm

2007 650r, 40K miles

The bike won't consistently start. Sometimes it's fine. Sometimes it will struggle, the FI light will briefly come on, and it'll start. Or it won't. Sometimes all I'll hear are the clicks of the starter.

Voltmeter shows a full charge (12.6V). When starting, power drops to 9.5, but sometimes as low as 7. When revved to 2.5K, it indicates 13-14 volts as expected. Disconnected negative lead and got no resistance.

Ground wire to frame looks clean.

So, it's the battery right? But the battery is only a year old.

Any ideas?

Yep, sounds very battery to me too.
