310 and 313

[300extreme#8]

how good are this kits and how much hp will it give me,i heard that 330 kit will keep up with 400ex's but will a 313.how much will they cost.all i want to do is keep up with a 400 or maybe be a lil faster.i prob.won't get a cam so will this be good without a cam or should i just get the 330 kit and then get a cam.

Powroll 313 you will be happy enough well im happy with mine but i dont have to worry about the power anymore really cause ill have a 400 in a few weeks hopefully if someone would buy my quad

I'm gonna have to say that neither the 313 or 330 will keep up with a 400ex without a good cam, and definately not beat it. i may be wrong though :ermm:

bump,so do you think i should just get a 330 kit

a 330 without a cam wont' even come close to runnin with a 400ex... u'll be lucky to even notice much of a differnce... a hi comp big bore piston and a cam go hand in hand... without both its not worth doin it really... wait till u get the extra 150$ and throw in the cam with the piston... if not ur wastin all the money on the 330 big bore and just makin ur quad run hotter for nothing... plus u probably aren't gonna have any bores left on the cylinder... i never heard of anything over 330 but a 330 stroked to a 355
