tring to find the right motor

[Tri-valleyracin]

im selling my lt250r and building my 300ex to compete in the 4 stroke c class. im tring to find the right motor 300ex, 350x or 250r. im thinking 350x or 250r but not shure what one. what u all think? its getting a long travel front and 450r shocks front and rear with a 350x rear end thats already on it. im not goin to buy a 450 or any thing cause in a year or so im getting a race ready z440

if u are racing the 4 stroke class, then that would kinda eliminate the 250r...no?
i would go with a 350x engine....

no because the 4 stroke class is a combination of the 265 class and the 450 class. just called 4 stroke i gess cause thas what every one is racing now. but im not going to build the 300ex im just goin to sell my lt250r and and pick up a honda trx250r to race with. cheaper and more power.

If i was forced to race a 300 in four stoke id get a 350X with a 390 big bore
