    Valve Clearance
    IN 0.15 ∼ 0.24 mm (0.0059 ∼ 0.0094 in.)
    EX 0.22 ∼ 0.31 mm (0.0087 ∼ 0.0122 in.)

    this is for a 15F. idk if they're the same. hope this helps.
    General rule of thumb, i've heard from several people that you want a little longer duration on both cams. Good luck

    inlet is 0.15 to .24mm (.0059in to .0094in)
    exhaust is .32 to .41mm (.0126 to .0161)
