250x jetting vs 300ex

[QuAdEr 317]

can u use a 300ex jet kit for example a dyno jet kit or a fmf jet kit for a 250x

I don't think so unless the 250X is bored out to 300ex piston size, or the jets you need are in the range of the ones you get with the kit.

dude u are stupid. the 250x has the same size cylinder and piston as a 300ex, just a shorter stroke.

And yes, u can use the 300ex jet in it.
