I've seen others say there is no washer. Mine had a copper washer on it though, just like the one oil plug.

I had the same concerns before I did my rotor replacement -- I noticed that the plug didn't have the sealing washer and that there is no reference to a sealing washer in the latest official documentation for the motor. Before I put everything back together I called EBR and talked to Tony, Mike and Danny about this. Here's the take-home:

1. None of them remember ever seeing an 1125 motor come from Rotax with a sealing washer on the crank lock port.

2. They agreed with my idea that it looks like the locking port plug is the same plug as the oil drain plug.

3. They all agreed that it would be a good idea to put a sealing washer in there when reassembling the bike.

Just for reference, the latest official documentation for the bike DOES NOT make reference to using a sealing washer in that spot. If you took your bike to a tech who was doing things by the book, he wouldn't put a sealing washer in there. OTOH, some people might have had their bikes serviced by a smart tech who knew enough to use a sealing washer even though the book didn't call for one.

time, did a search, and saw you mentioned it was a 16 mm allen for the tool, for the plug, and would i use the same copper washer that goes on the oil drain plug? thanks in advance. dan

I don't remember what you're referring to about 16mm. Link?

I haven't looked, but my recollection is that the crank lock port is threaded M12. that means that any standard M12 sealing washer should be just fine.

There is a washer in the 2009 parts diagram, page 22, part number 20. The plug and the washer are the same as oil drain plug with you can see on page 24. Part numbers are:
Q1050.1AM (plug with washer)
Q0091.1AM (washer)

Here's a poll regarding the plug that covers the port for the crankshaft locking tool. If you can, please answer all three questions.

1. The plug for the port for the crankshaft locking tool is an M12 threaded plug that's removed with a 6mm Allen wrench. It looks like the right side oil drain plug. Is it the same part?

2. When you removed the plug to access the crankshaft locking port, was there an M12 sealing washer on the plug, or was the plug naked?

3. When you put the plug back in, did you use an M12 sealing washer

It would probably be a good idea to update that other thread.

Based on what Yugi's found in the 2009 parts manual, it certainly looks like the parts manual confirms what I was thinking:

1. the two plugs are the same part
2. you should use an M12 sealing washer

what's interesting is that the 09 service manual refers to the plug by a different name than the 09 parts manual, and the 09 service manual makes no mention of using the sealing washer even though the 09 parts manual shows it in the diagram.

in contrast, the 10 service manual mentions removing the washer that doesn't exist on the bike, and the 10 service manual fails to mention putting it in when you reassemble.

there are lots of misteaks in these H-D manuals.

To the best of my knowledge, my bike has never had the access port touched before I did the rotor swap, and as I said, mine did have a copper washer just like the oil plug. Maybe someone was in there at one point before I bought the bike and I'm just not aware of it though.

Mine also had the washer, but my rotor was replaced twice before that.

Mine had a copper washer when I replaced my rotor nut. Used one for the drain plug. No problems. Check and make sure the washer is not stuck to the case before adding to the plug.
