Default Yamaha head bolts
Does anyone know what size are the head bolts on a 1989 70 HP Yamaha?

Thanks D. It's amazing, I have called various Yam dealers and nobody could tell me what size they were.

The genuine manual has a few pages dedicated to thread/bolt/nut sizes & torques.

Thanks again D. Would you know where I can buy a couple of heli-coils in Oz as opposed to buying packet of 16?
