Battery issues.. i think?
i bought my cbr 600 about 3 months ago, and right from the start, i was having battery issues.. i took it in for a charge at autozone, and seemed to be good. i'm unsure if it's the original battery, (it's a '99 so i doubt it) but recently i was driving home from work(about a 30 minute ride), stalled it out at a light, and couldn't restart it. i jumped it, started up,.. took a ride down the road, shut down for about 20 minutes, and it started up without the jump just fine.. sound like the battery? i just don't get why after riding for 30 minutes, it wouldn't start back up immediately, but it did after sitting for 20. could it be the alternator?
