Head bolt socket size

  1. #1
    Ok, bit of a noob question.

    What size socket do I need for my head bolts on a vts?
    I read somewhere that it's a 17mm but i've tried a few 17mm sockets and non fit inside the recess that the bolts are in.

    They seem like some kind of splined key.

    Can someone shed some light?

    Cheers.

    E14 female/inverted torx sounds right. Been a while since Iv stripped one
