    Equally importantly, where might you find a copper washer on your R1150. In my 15 years and 180,000 miles of ownership of my R1150R I don't recall ever encountering one.

    Sorry, snausages for fingersers.

    CRUSH WASHER. A crusher washer is the spray bar on the grizzlies and aren't interchangeable and not to be confused with the tailing washer.

    And they are a pain as once crushed down, the only way to remove them is to bleed a little.

    Copper washers are used everywhere. In fact, on my motorcycle, I got rid of the aluminum ones, mostly because I lost them. Any high pressure system that uses banjo bolts, like a diesel fuel system, use copper and seldom aluminum.

    We have about four kits of copper washers from itsy bitsy to about 3" in diameter. Can get them from any place that sells nuts and bolts.

    I found one on the oil drain plug, one on the transmission drain plug, and one on the final drive drain plug. Also when I replaced the OEM brake hoses I found copper crush washers on all the original banjo bolts. Granted, I bought the bike used a little over a year ago and have no idea who might have installed these copper crush washers. And to compound my ignorance, this particular bike is the first one I've owned since selling my CB900C back in 1989. My knowledge of maintenance of a modern motorcycle is almost entirely what I've learned on this forum and by working on my RT over the past year.

    When I changed the transmission and final drive oil I used new copper crush washers, but for the oil drain plug I just reused the old washer. So far no leaks, but on all oil changes in the future I'll use a new washer (or try annealing the old one as has been suggested on this thread; it seems like a simple enough procedure).

    On the 1150 alone you have:

    07 11 9 963 072 GASKET RING - A10X13,5-CU - brake system, clutch system
    Early clutch slave end M6 banjo
    11 41 1 342 807 OIL PRESSURE SWITCH - 0,15 BAR (to 12/02) - comes with copper ring
    07 11 9 963 342 GASKET RING - A20X24-CU
    07 11 9 963 308 GASKET RING - A18X22-CU - right cam chain tensioner
    07 11 9 963 342 GASKET RING - A20X24-CU - left cam chain tensioner
    Older model oil cooler return banjo's were Cu as well

    Plenty more on the fiche for other models if you wish to search.

    I had a series of Honda Civics over the years. All had oil drain plug copper washer. Re-used them 3-5 times, until a new one fell into my hands.
    My home boy who tracked/raced Suzuki GSXR's, had spare engines and stripped/rebuilt them over and over. Had a bin full of them, handed them to me when we did oil drains or brake rebuilds on my Honda motos. Seemed like a good idea. Not sure if they are OE.
    "Go copper, or go home." is my new catch phrase.haha!
