Ok folks. I'm officially starting the KZ440D restoration thread. I'll get some pics up as soon as possible but this project will likely move a bit slower than the 750e. Since I have a bike to ride, I'm not in a rush anymore. So far I've cleaned out the gas tank with vinegar (I recycled the vinegar from the 750 gas tank cleaning, worked fine) However the petcock on the 440 blew out on me on day 3. All the vinegar leaked out. Luckily by that time it had done its job. Rinsed it out with baking soda and water. Dried it out with some alcohol and then some air. The following day I decided I'd line the tank with some POR-15 (first time). Coating went flawlessly. Was surprised how much POR-15 I poured back into the can (reusable?).
I started to examine the petcock I noticed it had a large crack in it and a big chunk of material was free from the rest of the component. So, that petcock is toast. Any aftermarket petcock suggestions? This bike might largely be updated with aftermarket parts. The turn signals are smashed, the handlebars are bent, the headlight bucket is cracked, the gauges are cracked...and on and on. So, I'll either try to find a parts bike to supplement this one or update this bike with some aftermarket parts since I've never had that experience. Long way to go. The carbs on this bike were pretty well abused with gouges and stripped jets. Thanks to another member on the forum I got a pair of clean carbs and am currently double checking it's function. I'll try to hook it up to the aux tank soon, slap a battery in it and try to get her to start. If she runs, then it's off to the races.
