i've got about 500 bucks and i was thinkin of gettin a white brothers rev box, and an hinson clutch kit, and im goin to rebuild it to a 416 think those r good choices, i ride trails once and awhile, some little pits and the track.

what are your current mods?

Like you will here from everyone else, power is no good unless you have suspension. Suspension 1st, then power.

my mods r a uni airfilter, maxxis razr, and itp rims. stock suspension doesnt bother me i can do doubles fine i just need a little more power to get to speed before the jump. i only weigh 105 pounds. thanks

get an slip-on exhaust, you will definitely notice. if you want even more, get a cam.

cam and piston in 400ex is reliable, just make sure you get a "drop-in" cam.

Yeah, Hotcams is probably the most popular drop in cam.

I have the JE 10.5:1 piston and the hotcam, and I love it. I have the sparks full system x-6.
