kfx?????????

[02400exracer]

my friend has a 04 kfx with a 440 kit on it and stock exhaust. I have a 05 yfz with hmf exhaust. he is always talking smack that his is faster, and will not race me anywhere except the road and i will not race on the road. which do you think is faster.

depends on what all else is done to the motor. if he has just a 440 kit with no porting done, stock carb, stock intake, and a stock exhaust there is no chance he will stay with you. if he will only race you on the road any nowhere else he must be scared about somthing:p

next time he says lets race on the road tell him to put his money where his mouth is and race him.... road, dirt, sand unless you really suck at riding youll still smokem.

my bros 06 yfz has a full hmf and its scary fast, and the stock pipe on the 440 is probably Restrictive, i think ull win
