The history of SACS Engine

Now I'm making content of my Japanese Edition. The content is about the history of SACS engine. It past 18 years or more since SACS system appeared, and there are many motorcycles with that system. But I have never seen a table about the relation between the Model-Code and the Engine-Code.

For example, the model code of My R750L is GR7AA and it has a R716 type SACS engine. But the Japanese domestic R750L's model code is GR7AC and it has a R719 type engine.

I need your help to survey the relation. Please let me know about your SACS motorcycle. Not only GSX-R series, but also GSF, GSX, Bandit welcome!

. And write the relation simply. When it starts from JS1, please write from the 4th to 8th characters. The model code will be found at the neck of your motorcycle, and the engine code will be found near the oil filler cap on right side of your motor. First 4 characters is your engine code.

ex) 90R750L / GR7AA / R716 / your comment

When the table will be completed, I'll try to translate it in English.

Thanks in advance.

Difference of SACS Engine between 750cc family and 1100cc family

When you try to make 7/11 or 11/7, you have to know the difference of crank case mount bolt size.

The mount bolts of red arrow are different from 750 and 1100's.

10mm in diameter bolts used for 750cc family's, and 12mm for 1100cc family. That is, you have to change the size of engine mount plate holes.

Other mount size and places are same each other.
