Just wondering if there is anyone out there who can shed some light on the casting marks you see on heads and cylinders on older 86-88 kx 500's. Mostly which years these were cast?
I've got a few a-1 and a-2 heads.
On the cylinders as well w7/20 ,w7/24, 7/27
Is there any reason why some of the earlier cylinders have no kips stamp inside the box?
