need more power

[zoom400ex]

i am looking to get more power out of my 400. i dont do alot of mx racing mostly trail riding and drag racing. what kind of motor mods do you think i should get so i could be a z400 or maybe a raptor? I dont wanna put a real lot of money into my motor. maybe like 300$ ?!?!?!?. i am also not very mechanically inclined so something that would be easy for me to put together. or maybe someone that would do the work for cheap.......... any input would help thanks,

Porting work would help

440 kit. It's only about 170$ for the kit and about 150$ for a machine shop to press the sleeve in, then reassemble it yourself.

bore it to a 425,get a drop in cam, 11:1 JE piston, and get an exhaust, that should give you a pretty good increase in over all power
