I was thinking about getting a piston for my 400ex. I was wondering if I got a piston with a higher compression ratio, would I need any other mods or not? Would it be worth the extra compression or not?

A 11to1 piston & rejetting the carb makes a big difference.I think it is by far the best bang for the buck.
