I have a 400ex bored to 416 and have a stage 2 hotcam. I have a krome dg slip on exhaust without spark arrester. Stock intake and carb with foam filter. I was wondering if I should change my jets, and if so what to? If I should make more airflow through the intake box with holes? It runs good to me right now but I was wondering if this setup would be hard on my motor or anything. I’m asking to see what the best setup would be for me with what I have? Any help is greatly appreciated.
