Hello I have an 04 400ex; FMF pipe, rev box, k&n intake, choke delete, steering stabilizer, fly bars & armadillo skidplate. What are some good upgrades I should do to bothe the motor and drivetrain anmd still maintain the reliability these are known for? I heard the 450r shocks are a must and also doing a port & polish on head as well as a higher compression piston..are these good? what else? Thanks!
