My "wont start" situation

[roanoke]

Okay, I rode my bike all day yesterday with no problems, ran good and started good. Hopped on to go to work and wouldnt start, so i got another way to work. Today troubleshooting all day. Put car battery on for jump (car off) would try to start "chacha chacha chacha" but no engine turn over. Determined battery is shot so i ordered one. Moved on to spark plug. With new plug engine starts but doesnt revv like it used to. It does initially but the more you turn throttle , it pops and skips. Idle seems fine. So i think it may be bad gas. I used ghetto gas. What do you all think? I put a capful of berrymans in it for the first time this season. Waiting on battery to continue. If i feel good to ride it/still acting wacky, I'll take it in to the shop.
