If you are talking about replacing an 8 valve motor for a 16 valve version it may be tougher than you think, and if we are looking at shaft versus chain drive it may be neigh impossible.

Give us a little more detail about what you have

The 16 valve 1100 & 1150 are the same motor mounts. Ray.

It should be possible to put 1150 cylinders on a 1100 lower end. If I was going that route I would go for a big bore kit and make a real difference. 50 CC is not a large change by itself.

The CYLINDER head is the biggest advantage with the 1150 over the 1100 as the 1150 head has bigger valves & more airflow. Ray.
