i have a 05 zx10r motor with 13.5:1 pistons, mild cams is basically all i have done to the motor, compression is gonna be between 13.5-14:1 what fuel should i use? im being told mr12, is it a good safe fuel?

 

[Unforgiven]

mr12 is usually for stock compression motors. it would probably be fine, but i would recommend some kind of high octance fuel. i would think you would get more out of it. mr12 burns very easily.

13.5 is not that high of comp. mr12 with good tune should be fine if for some reason need more anti knock(octane) mrx01:buttrock:

just saw the 14 to 1 part i would lean towards mrx01:2thumbs:
