my friend just bought an 03' stock kfx400 and brags about it constantly. first he tells me that he raced a cavalier w/ a turbo and beat it for the first 1/4 mile, and then he said the car was going 83 mph on the road and he was right beside it. then he said he can smoke me easily, im pretty sure hes full of **** because he has the same thing as a z400 and i can barely beat my freinds piped z. what do u all think?? does 83 mph sound like BS????

With stock gearing the rev limiter kicks in somewhere around 67-70 mph. Unless its geared to the moon and has some decent Hp, I wouldn't expect more than 70.

the kid that has the z400 has 22" tires and i have 20" tires and he also dropped a tooth on the rear sprocket and i have stock gearing. we drag about 1/4 mile and i beat him by about 2 quad lengths, same way when we switch quads. yea i was thinkin that he was full of it since the kid that sold it 2 him said he could only beat a stock 400ex by 2 quad lengths

According to this handy little calculator I found online: http://home.earthlink.net/~gellett/ltz400.htm
He should pull 77 mph IF he had enough power to pull that gearing. With just a pipe I doubt he has power to pull 77 with 22" tires.

he doesnt have enough power in 5th gear unless he hits the rev limiter in 4th, and then 5th gear pulls slowly. but his low end power sucks and that is why im not going to gear my 400ex any higher. that calculater site is pretty interesting, but the rpm makes a huge difference in the top speed

Sounds like your friend is gearing for pure top end...so you guys must have enough space to get up to speed...If that's what your drag race is about then figure your torque/hp curve and then find the optimal gearing for top speed. Otherwise set a given distance and do a true drag race from point a to b and see who gets there faster. Unless his power is way up there, he'll only be able to do one or the other.
