whick big bore kit?

[Atreyu]

For a 300ex what do you think woudl be the best bore kit? I want it to be semi-reliable but also able to beat piped or stock 400s. Im leaning to the 330 kit but hows the 313?

330 are badazz man..i had one at one time and it would beat a stock 400 and hang with a piped 400

I can't speak from experience, but I doubt if a 313 will keep up with the 400.

Check www.powroll.com they have some awesome engine kits that will eat any stock or piped 400EX
