[QUOTE="steve125, post: 747447, member: 20272"] The U4 and U2 have 6% 02. My favorite mix in my YZ144 is 50/50 U4 and U2, that gives me close to a 95 MON. On my 4 banger it's straight U4 and it works great! On a std. 2 stroke that runs well on pump, the U4 straight would be a great choice. [/QUOTE]
