This weekend I installed a White Bros. cdi, installed a K&N filter with the lid off, and jetted the carb on my brothers 2000 400ex and wow what a difference it made.
We already had a FMF Titanium 4 muffler and Powerbomb header installed but had stock jetting.
I set it up with a 160 main, 42 pilot, and set the fuel screw to 2-1/2 turns out.
It has great throttle response and seems to rev faster and longer.
I can't wait to see how it runs this thanksgiving. It had plenty of power with just the FMF exhaust.
