The Kawasaki ZXR 750 R, sometimes referred to as the Ninja ZX-7R, was a limited edition superbike from the early 90s that boasted a number of cool features, such as an aluminum tank, magnesium crankcases and a valve cover. The engine came to us in a rather pitiful condition, the bike had been sitting in a farmer's barn for a long time and the surrounding animal production did not exactly benefit its surface. The engine was in good condition inside, the new owner wanted to restore the engine to its original condition and look. We used a pulsed laser to remove all the dust, grease, mice fur and most of the corrosion. Unfortunately, the engine block was quite oxidized, in addition magnesium, or alloys with a high magnesium content create a very thin layer of oxidation products during laser cleaning, which had to be removed in the same way. The result can be seen in the photos.www.lsrservices.cz
