I own a 2006 ZZR 600. I've owned it since January and it hasn't ran right since I bought it. It runs fine until it get to about 150 degrees then it starts sputtering like it's getting to much fuel. The carburetors have been jetted and it has a yoshimura slip on exhaust. I don't know it's that would have anything to do with it. I'm hopping someone on her has been through a similar situation with this bike and can help me out. Thanks.
