yea, then you can get a 450x big bore kit for it:D

Powroll makes a 430cc stroker kit for the 350X engine. It will run circles around a stock 400EX.

I need info on the 250X/350X swingarm swap. Maggot, you have any info on that? :confused:

[bradley300]

when both are built, the 300ex motor will be the more relibale of the two!

yeah i think thats true...haven't herd it but i know the 350x doesn't have berrings on the cam...so i can assume that it isn't as reliable as the 300ex that does....so you have to pick between power and reliability

eh the 350x rear end on the 300ex? i think i got some info on that ;) pm me
