my stock 400 used to keep about 1-2 lengths on a piped z400 across a feild...of course, my freind on the z weighed about 100 lbs more. my new stock 450r pulled 4-5 lengths on the z, and that was on break in at about 1/2-3/4 throttle---so do the math. now...with the hrc, the holeshots, and the 13t sprocket, i can walk away from a worked/piped banshee, untill he hits 6th gear at which point he pulls away. now he got a dirtbike instead..and i cant keep up at all, its a kx500 haha.

 

How do you figure a piped 400ex can not beat a stock z400. I do it all the time and can even run close with piped z400's. Everyone says how superior the "z" is to the "ex" but the difference is sooo close as to be negated by the rider or wieght difference. Must say a lot for the "ex" when old tech. is sooo close to cutting edge.

 

I just got through doing a 300ft. drag against a 450R and a YFZ 450 with my 400EX. I beat the 450R 2 out of 3 times and beat the YFZ off the line all 3 times. The YFZ beat me by about 2-3 bike lengths. I beat the 450R about 1 bike length and the 450R beat me by half a bike length. This was on wet / dry sand. Me and the bike out weigh the other riders and theif bikes.[img]i/expressions/face-icon-small-happy.gif[/img]

I run 16/38 gearing, and maybe if I went with the 15/38 the YFZ might not beat me as much.

 

everyone aorund here is saying the 450r is junk and that 400ex can take them. that is waht my friend was saying. i told him i find it hard to believe but he wouldnt lie. i trust him. he also said the 450r blew up the same day. yfz is fast as hell. im a honda guy but i know the yfz is faster. kinda pisses me off cuz honda should have made something better.

 

You are right each race with z or kfx i lead till fourth speed and after they start beating me

 

Are you sure your jetted right?
