Hey guys. I have a 2000 zx9r that seems to be having a problem with hard acceleration. Whenever a give it full throttle I lose power at high rpm (8000 and above). Its like abrupt on/off throttle response during hard acceleration. I have herd that this is a common problem with the zx9r, so hopefuly there is an easy fix. The bike has a high flow air filter, full micron exhaust, jet kit, and flow commander if that helps anyone. I have looked at the spark plugs already and they look to be fine. So now I dont know what eles I should check. Thanks for any help you can give.
