What are the differences between these two chassis and engines?

Thanks for your help.

I'm not particularly knowledgeable in this, but here's a few. Others with direct knowledge please feel free to correct me as needed.

1. Biggest major engine change, redesigned cylinder block to adopt larger and revised intake/exhaust ports and manifolds, similar to what the 7th series Speedsters used.

2. Bijur goes to automatic from "push daily", revised drip plugs.

3. Revised type shock absorbers, wider and longer springs.

4. Mechanical fuel pump now standard.

5. Transmission changes; radiator shutter thermostat location changes from front to rear of the tank.

Very helpful Dave and interesting. My education always continues to grow.
