Hey all! I am currently Running a 2002 400EX and I planning on Ice Racing it this winter, I currently have the Big Bore 440 Kit, Hinson Race Clutch, HMF Bill Balance 450R pipe and I run Amsoil Full Synthetic. Even in the summer months trail riding or racing motocross I have some back fire and popping issues and as far as I know this bike has never been jetted even after the 440 kit was installed. I bought the bike like this. I race in the Upper Peninsula of Michigan and its pretty cold in the winter, can someone help me decide what kidn of jets I shoudl run for this winter racing and possibly for summer motocross!! Also I'm curious as to what other performance parts would make my bike even faster, pleaaaassseee HELP!! Thanks!!
