[QUOTE="_JOE_, post: 1400202, member: 77507"] Compression ratio. Stock should be 12.6:1. The others are higher compression models that may require race fuel to run. My old crf ran fine on pump gas at 13.5:1 compression. 14.2:1 would most certainly need better fuel. Watch the valvetrain closely in that bike, I'm pretty sure they're notorious for grenading.
