hopfully somebody will wrrite back with a reply soon i would like to know 2.but i want to put a 350x motor in mine does anybody know how hard that is?

 

Absolutely, positively --- NOT! The conversion is not easy, fer instance -- the cam on the 350X rotates in the opposite direction of the 300EX!

Yea, it can be done, but you'd end up with some serious $$$ into the project, unless you're a master R&D guy. In which case, you'd just port the stock head and install bigger valves to get the same kinda flow you'd have on the 350X head. Which is still less than a stock 400EX has.

But you can install the whole 350X engine easily into your 300 EX or 250X chassis. There's even a company that makes a pipe for the conversion. I have a TRX 350X, (250X chassis, 350X engine) and like it. Unfortunately, it's nothing compared to a 400EX for power -- but that's what I've got my "R" for :-)
