07 CBR Starts Runs Turns Off?!?!?!
Ok so i did search for my problem came up empty so here it goes. Its kind of long so please skip to the bottom 2 paragraphs for the main question. Sorry
Some back story. I have had the bike 5 years. Still on stock battery. Never had it hooked up to trickle charger so it has run dead many times over the various winters from the cold.
Last season I couldn't start it no matter how many times i started it. Turned out the gas was old, so we siphoned it out and the thing started up after a few tries with fresh gas and a fully charged battery.
Fast forward to today. Battery seems to hold a charge though not great. It died on me at work today. I grabbed the trickle charger from home and it wouldn't start.
Charged it again and it started this time. But after about 10-30 seconds it just died from idle. Last time this happens it was because of the gas. But I just put a fresh tank in 3 days ago.
After starting it 3 times and having it die shortly after idle for a while (didn't even have time to put on gear before it died) i just pinned the throttle to keep the thing alive long enough for me to ride away. And sure enough didn't have a problem at lights or anything else.
So finally my question. It the bike will start even with a battery I'm sure isn't fully holding a charge then why is it dying after the bikes already running? Once its on shouldn't the battery play no role in the bike at all?
I want to fix this tomorrow. Do I need to go buy a new battery or is there something else wrong with the bike that needs replacing? I don't wanna blow my money on a battery if thats not the issue.
any help is appreciated. thanks
