I bought another 09 zx10r but im having power issues. When i bought the bike had 3000 miles on it. the issue is it set up for 5 years with gas in it. I cleaned the fuel tank and replaced the fuel pump first time and rode it. The next day i took the tank back off and inspected it and i still had rust in the tank. But i could not get the RPM past 4 grand. So i clean it out once again and put another fuel pump and fuel injection rail on and it did better but now i cant get past 6 grand with it breaking up and barding down can't go but 55-60 MPH. Can someone give me some advice on what to do?
