Browsing Craigslist, and found a low miles '95 K75 engine for 70 bucks, less the water pump, fuel injectors, with the clutch. I'm going to put it on my bike, when I am replacing the clutch, as my 100k engine is getting a bit tired (uses a good amount of oil, blowby, shitty mileage, etc). Leaks in a few places too. Think there may have been poor maintenance in its past. However, before I put it in, I will go through the engine to make sure it is fresh, break the glaze on the cylinders to make sure I can seat the rings/break-in as I would like, reseal, check clearances, etc. Any thoughts? I am trying to decide how to clean it. I am thinking plug up the ports, tape over the open oil pan, and hit it with a pressure washer and soap before tearing it down. That way I can start with it somewhat clean. For breaking the glaze, it has nikasil bores, so I will scotchbrite and soap it. If need be, I will track down a ball hone. Once it is opened up, I think I will set up a diy spray booth for the pressure washer, and use that on all the aluminium parts. With the head, should I lap the valves? I will be replacing the valve stem seals.
