Are copper crush washers any better than aluminum, or does it not matter?

No way! A lock washer would gouge the sealing surfaces, and plus it wouldn't seal, as it has that split in it. A crush washer is simply made from a soft metal, copper or aluminum, so that it can be pressed tightly to the sealing surface and conform to any surface irregularities. Also note that the oil drain plug doesn't require hardly any torque, and the threads are in the soft(er) case material.

On the KLR I would say that it generally doesn't matter. Which one is softer and therefore seals with less applied force greatly depends on the alloy of each. The only instance where I could see choosing one over another is where you have to be concerned with corrosion, as aluminum generally withstands corrosion better, but the crush washer on the KLR doesn't stay on long enough between oil changes to matter in that regard.

I usually buy my aluminum crush washers at the dealer. Recently they've been out of them. The parts guy said they're simply an aluminum washer you can get at any hardware store. Couldn't fine them at Ace. Was parts-person right? Bogdan> The washer in question is a crush washer which is made of aluminum, which > is very soft, and forms a seal at the drain plug.
