'08 CBR 1000 fuel delivery problems.
i just got a '08 CBR 1000. Ran awesome. I cut the pipe, put a straight pipe (it's loud). A few weeks ago i started having problems. When i suddenly hit the gas all the way, it'll die on me. Had to put it in neutral and restart it. But now it's even worst. Won't start at all. If i tilt the bike i can hear the fuel pump priming, and i'm able to start the engine, when the bike sits straight up, engine will shut off, and can't hear the fuel pump. (only when the bike is tilted)
Please guys, help me out on this. I'm desperate w/o it
Thanks in advance
