Going through some Ebay listings for the KZ and I found new inner carb boots, some used and new regulators, even a replacement battery tray, seems to be plenty of parts at decent prices. I found out this motor has roller bearings, has only 3.2 PSI oil pressure running but is high volume. Some Police version speedos are selling for hundreds of dollars, this one is just stock though, frankly I wasn't enthused about breaking away from Hondas, its bad enough where I work we have a fleet of concrete mixers that years ago were everything from Autocar, to White, Mack, Kenworth and Peterbilts.
I am setting up a large dry erase board at my bike workbench with sections on each of the bikes so I can prioritize each project.
Like the 80 CX500 has very bad head bearings, thats a red project as it catches when turning.
The 81 Gl1100 will get stripped to the frame and sandblasted, powder coated and may be a rebuild through the winter, if nothing else I will have extra parts for the 83, it still has a good front and rear brake master cylinders, the air shocks, pump and water separator I believe. U figure it will cost me less than $500 to get the KZ on the road, thats for tires, carb boots, a new regulator and battery, I may just put some Shinkos on it, again I am not enthused on this bike for some reason, nothing like the Goldwings.
