Hey i need some help. I have a 2002 zx6r with 5600 mi. I recently put a bolt on D&D (which sounds beautiful). And had it lowered 2 inches a couple weeks ago. Have never had any other work done on it but that and scheduled oil changes. My question is that I have experienced a power loss for some reason. I can pin the throttle in frst gear at 9,000rpm and it just goes. It used to bring the front end up. Another thing is that I can be cruising on the highway n 6th at 7,000rpm, drop two gears and it feels like it's going nowhere fast(it will slowly pass a car). Any suggestions to what could be causing this? thanks...
