400EX 10:1 or 11:1
I would go with the 11:1 there very reliable Have it on mine and its ran great for a year never had any problems with it (nock on wood)
But the less reliable is the 13:1 compression and things like that
the 11:1 piston you have the option of running race gas or not but you do half 2 run the 93 octain in it all the time no cheep stuff
