Copper sealing washers.

[jetmechmarty]

I had hoped to find this in the TECH section, but I failed to find it. I'm getting ready to put a bottom end together and I wish to gather all the copper washers for this bike in one order.
I found M8 with a 12.4 mm outside diameter to go under the six crown nuts on the bottom.
I need:
The four for the left case cover. 90430-06014-00
All of those required for the oil feed tube unions. 90430-10171-00 and 90430-14043-00
Two that go under the holder for the front cam chain guide. 90430-11033-00

I already have those for the top of the engine. My hope is that someone already recorded these, and I simply failed to find it.
I'm attempting to but this whole mess from McMaster-Carr.

I’m certain @5twins will have this info.

Lol, I'm afraid I don't. I never replaced these washers, I just clean them up, anneal them, and reuse them.

My local Ace Hardware has a good selection of metric coppers.

You’re fortunate south of the border to be able to get such things at a local hardware store. For me it’s online shopping or special order from an industrial supplier.

It may come to that, but it may not be quite local. Good old fashioned hardware stores are getting harder to find.

A nearby "Runnings" store has quite the extensive hardware section. Check them out, if you have one in your area...

Seem to work just fine - even on hyd. brake fittings;

I buy a lot of specialty stuff from McMasterCarr, but sometimes Amazon is just too easy

sounds like a remote place you live in, so best option may be to reuse old copper washers. There are better option than copper for sealing, in my opinion, alu or stainless steel washers with bonded rubber in the center, keeps the oil where it's supposed to be. Downside is they can only be used once. I don't know where to get them in US (in metric), probably an MC store that deal with european or jap bikes - I know they were used on BMW's.
I had a bunch from when i lived in Europe but my stock is running low so unfortunately not able to spare any. they kinda look like this

These are the one I use all the time. But you can anneal the old ones.

My go-to for this type of hardware is belmetric.com. They will ship any quantity and have a good selection.

Bought a similar kit on Amazon too. They all seem to be the similar but I bought the kit with thicket, large diameter washers. Most were 1.0mm thick.

I bought sealing washers from Fortnine. Had one banjo bolt I couldn’t get to seal with copper or aluminum washers. The sealing washers worked well.

Between McMaster-Carr and Amazon, I should be in great shape.

I’ve used the kit from Harbor Freight. Other than the side cover and head bolt washers they seemed to work for me.

I’m stocked for engine and brake fittings. I have three more XS650 engines I could potentially go through.
