    I have a 2006 WR450f with a FMF Powercore 4 slip on exhaust on it. The bike is running lean right now and backfires on deceleration. I know I need to up the jets to richen the fuel. I am about to do the air box mod to the bike to draw more air in. Just wondering if anyone knows what size jets I should put in the bike to save me time. I live in Cleveland Ohio where elevation is 500-1000 ft. Thanks
