This is for all my bored out 400’s, I bought this 400 with a carb prob, wasn’t jetted and running lean, I ended up with a 180 main and a 48 pilot, this bike running lean was pulling trucks on a stock 400ex which was tested truly as my brother owns a completely stock one, where am I at? 416, 426? 440?(highly doubt the 440) but I have a K&n intake, the jets and a slip on
