stock is like 8.9:1 or something Been a while since I have mine. I also bored it out alittle so the added power was nice.

actually 8.9 is the 300EX and the 250X was 9.4:1 ;) I also run a 12:1 Wiseco on 93oct. Has good power with a good pipe and filter. Must re-jet of coarse..

93 octane wasn't enough for my 12:1 250x.
