Hi wondering if anyone can please help. I have a 03 600rr and a couple weeks ago I was letting it run and when I shut it off I left the key on, I didn't know I'd left the key on til a couple days later when I went to go ride it and it was completely dead. I jumped it with a car that was not running and rode 100miles that night and came home. A few days later it started just fine so I shut it of right away. Now a couple days after that I went to go start it and it wouldn't. The battery is good. I checked all for plugs and they all get good spark. Please help me if you can with any ideas of what the problem could be
Thanks

how sure are you that the battery is good? usually when you let a old battery run flat theres no bringing it back.

what does it do when you try to start it? does your fuel pump prime when you turn the key?

I charged the battery it read 12.88. But I tried the battery out of my buddy's 05 cbr his read 13.88 and when we put his battery in my bike it did the same thing. When I try starting it everything sounds normal until i hit the start button it smells gassy though when I try starting it

so....what does it do exactly when you hit the start button? does it turn over? does it click and not turn over? can you hear the fuel pump prime when you hit the start button? does it crank slowly? or faster than usual?

we need much more details to help you.

oh, and just because a battery reads proper voltage doesn't mean the plates haven't fused together and caused it to short out and go to zero when you go to crank it.

Take the battery to an auto parts place and get them to do a load test on it to simulate cranking.

Could it still be the battery even though I already tried one that is good. When I hit the start button it sounds like it wants to go it just won't. The more I try to start it the the more it sounds like it doesn't want to start though. I can try putting a video on here so you can hear it if that would help

Are you saying the engine will crank and turn over it just will not fire?
