[Jon114xxx]

I just bought a stock 2003 z400 with only nerf bars and i want more out of it to possible start racing.. the only problem is that im 15 and work but still dont have enough money to buy like a 440 kit or something.. so, inn the mean time, what should i do to my z? (performance wise)????

Well depends on the type of racing really, MX or XC.
I don't really think you need a 440 kit for XC, get wheels, tires, suspension, skids, 13tT sprocket, first, then maybe a pipe and filter and go from there. MX not really sure, someone will chime in I'm sure. Good Luck.
