I all, i just bought a 04 400 EX in mint condition the other day and i was just wondering if it should be rejetted with a K&N air filter and a yosh slip on? The thing starts up and runs just perfect with no poping on deceleration or anything but i just wanted to be on the safe side. I was also wondering how many gallon the gas tank would be. Thanks alot!
