Head bolt socket size
 

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. :y:

E14 rings a bell

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

Excellent, thanks a bunch!
