I have a 400 sport too, mine is heavily modified. It has an aftermarket pipe, vforce reeds, porting,bigger piston,higher compression head, clutch stall,minuki carb,starter delete,oil mix delete, and kn open air filter. It is stupid fast for a sport it will outrun my friends 400ex like thats its job. There are some downsides though, i dont run it in the winter so i wont blow it up, you cant take long rides at top speed You have to run expensive oil like clotz. but on the upside you would have something no one else has, and i havent found a hill it wont climb. If it was me i would choose the pred its much easier to maintain and better suspension, and no worries about blowing up.
