Kawasaki KZ650 cafe-racer. Rotor holder.

Well, this post is dedicated solely to the rotor holder I made for the Kawasaki KZ650.

Application of this tool to the KZ650 engine, unlike KZ750 and Zephyr 750, is limited by only two cases:  installation/removing alternator (dynamo) rotor itself and installation of secondary shaft gear (when a non OEM special tool is used). In the case of KZ750 and Zephyrs it is also used to remove/install secondary shaft nut. As I have both KZ650 and Zephyr 750 engines, I decided to make a proper rotor holder.

I didn’t like the idea of making U bent from three pieces of tube. However, after a short thinking I  suddenly realized that I already have all necessary (well, mostly all) components at hand! The moment the idea sprang in my mind I was rummaging through the content of the locker where I store old used (some of them in fact are mostly new) drive chains, sprockets and brake discs. In a matter of minutes I was holding in my hands a perfect blank for future rotor holder. It was a rear sprocket from some Honda. All else was just a matter of simple operations: cutting, hammering and welding. Soon new special tool for Kawasaki rotors were mostly ready and I liked it as it was: bare metal with zones were it changed the colour around welding seams. So I cleaned the handle  with sandpaper and wire brush wheel and treated the tool with rust converting/protective chemicals. After this all that I had to do to finish the rotor holder was to buy two threaded pins with hexagon sockets and slightly modify them on lathe.

Dunno how to properly describe the tool I designed. If there was division of special tools into defensive and offensive, this tool of mine would be for sure classified as offensive. But anyway, let’s stop writing words and take a look on rotor holder:

The ends of both pins were processed on lathe to fit holes in the rotor. The height of the reduced parts is less than the depth of holes, so magnets couldn’t be damaged incidentally.

This special tool may be used in hand-to-hand combat, recommended for warriors of 44 and higher levels (for dwarves from 32 level). With patented  “death star” attachment it could be turned into a portable annihilator. Crash the rebellion today, save the Empire tomorrow. Beware of recoil. Do not use it on pets. Smile.
