If I read that right sounds like you have a starter problem of some sort, From what I read you have the sound of the starter turning but the engine isn't turning. That wouldn't be a battery issue that would be a failure is the gear drive train some where not putting the power from the starter motor to the engine. I hope you mean the starter just bogs and doesn't turn since then it would be a battery/connection issue. 05 falls into the weak starter idler gear range, did your bike backfire while trying to start? I hope not but I worry about that happening to me. Lucky my bike doesn't backfire while starting I guess. Any unusual grinding noise with the starter sound?
