i just bought a flawless 2005 zx12 with 7800 mile on it. i love it. The previous owner didnt ride it for two years. I took it home and noticed that it would bog out at 6500 rpm while under a rev in neutral. Some say the injectors may be clogged up and some say the power commander may need to be re-mapped. i just want it to run smooth again. what should i do?
