here is a link to an official Kawasaki page where you find explosion drwaings of all JAPANESE Estrellas (and other Kawa bikes since 1985).
Click the first menu in the first frame and choose your Estrella model.
Click the button in the same frame.
All versions of your model will be shown.
click onto the button of the model you have.
A new page opens.
Click the menu in the second window and you will find 6 explosion drawings per page.
Choose the drawing you need and click the button or chose next page.
If you click the button belonging to the drawing, the drawing enlarges.
If you click a part number, you see the japanese name and the japanese price for it!
Hope this will help you.
You can't save the drawing with the IE, but you can save them if you have Opera or FireFox!
There are NO drawings or part numbers of the European models (but most parts are the same).
