300ex vs 400ex what do u think?

[highflyinEX93]

A kid said his 400ex with a 407 kit, hotcams camshaft, and white bros filter could beat my 300ex with k and n air filter, outerwears pre-filter, Dyno jet jet kit, fmf exhaust, hotcams camshaft, and new bearings. Who do think would win in a drag race? also let me know what else i could do to get more speed and power out of my machine.

My guess would be that he would still have ya but I don't know for sure

[Butters]

yeah he will beat you.

The only way to find out who is faster is to actually race!

[ethanp87]

the 400 would win in a drag but you might be able to beat him on a track if you can ride good.

[YFZ450Ridr]

he will beat you in a drag race for sure.

[2004exrider]

well 100 more cc's, and bigger piston his would win.

[300ex13]

if u had a 330 kit in it and his was a stock engine (no internal work) you would give him a great run for his money!!!! the 330's wake the machine up a lot. a WB eseries will help this kit run a lot better it gives best performance with modified engines.....

[honda250xrider]

the 400 should walk away

[jak1389]

the 400 would win most defiantley in dragging

[yellowex26]

i didnt even know they made 407 kits for a 400ex

I was with you right up until you said the e series gives the best performance with midified engines.:huh

It depends on how you do the math, a little bit of rounding can make the 406 bore into a 407, no real difference.;)

[87250rxrider]

not even a competition... the 400ex should walk away with no problems, unless the rider can't ride at all.

[Cody_300ex]

This Is a BS post. Hot cams does not even make a cam for a 300ex/250x motor. I Have between 500-550 in my 300 motor and I edge out my friends 440 with a weisco 440 kit, and a stage 1 hotcam.

[fasterblaster09]

400ex..no doubt

[hondardr4life]

You will lose. They key to a fast 300ex motor is a port and polish job. Mine walks away from my friend's and they all have piped 400's.

[xx3003xrdrxx]

buy a faster quad if you wanna beat him :rolleyes: thats what im gonna do haah :macho

[redexrider4290]

i dont think your 300 would beat a stock 400

I dont think 300's are that fast unless you change the gearing alot and youd need some hop ups then because 300's dont have that much power

Its how good the person is at racing...
