maybe this should be in the performance mods?

[secluded]

but anyways, has anyone put a 400ex cylinder, head, cam etc. on a 350x? would it even fit? whats the stock HP of both bikes?

[ATCRYDER]

hmm....Ive never heard that before...or anyone doign ti for that matter.

I dont know why but I dont think its fit :confused:

But doesnt the 350X produce the same HP sd the 400ex? Its like

-2Hp ?

yeah i thought i saw something on the board befaore that said the 350x puts out the same horsepower if not more than the 400ex.

[MR ATC]

the 350X has 28HP the 400ex has 28.4HP to do this conversion would be a big waste of time for .4HP. therfore i have never reshearched its compatibility if you want 400cc you can go severall ways one is a bore kit or a bore and stroke combination both will produce about 38hp or the same as a 400ex with a 440 kit. the 400ex is not as advanced as the older 350X motor
