185 Cylinder Head

Bare head. All valves, springs, buckets etc removed This view shows the exhaust side of the cylinder head A close up of the exhaust ports Side view of the head
Inlet side of the head Note the large ports, this is to accommodate the TVIS arrangement that is found on both the 165 and 185. Also note the fairly "blunt" nature of the divider between the 2 entries to the valve area An empty cylinder head A close up of one of the cylinders
A closer picture of the combustion area You can quite clearly see the valve seats that are pressed into the head in this picture
