I think those shims are made by K&L. Seem like reasonable quality to me.Ed

Mine too! They looked different, but I'm sure they're tempered. The ones I got were packaged with the label K&L, who make a lot of rebuild kits for carbs, calipers, petcocks, master cylinders, etc. for vintage Japanese. Z1 has a great reputation, and I can't imagine them selling junk shims. Or am I being naive?1979 GS 1000

I installed 4 from Z1 yesterday. Unfortunately, I needed more. The PO had the bike for 8000 miles (of the 28,000 on it) and had never done the valves. When I checked them yesterday, exactly TWO of the eight were within spec. I had ordered a couple of 2.65 and 2.60 from Z1, but needed one more 2.60 and 2 2.55 to be able to get them all within spec. I left it apart and I'm going to stop by the dealer tomorrow and hope they have a dusty box of shims somewhere in the back. If not, I guess I'll put it back together with a couple out of spec, hit the shim trade thread, and revisit it in a couple weeks. Here's a question. Will the gasket need to be replaced EVERY time you pull the valve cover, or is there a good chance that with only a few hundred miles on it I'd be able to reuse my gasket.

Gasket should be okay. Some members here grease the gasket to keep it from sticking for that reason.Ed

I got lucky on the sheared bolts too. Not gonna need the Heli Coil. There was enough nub left to spot weld a nut on them to get them out.

Realgasket.com makes orange silicone gaskets that can be reused. I'm waiting on a shim to finish up setting my valves, then the realgasket goes on. You only tighten the valve-cover bolts until the gasket is compressed my 1/3. The hardest parts of regularly checking your valves are, 1): getting the bolts out (the PO snapped one off on my GS 1000, and I'm not sure if I can get it out, but it wasn't leaking before, so I think I'll be OK), 2): getting the old gasket off, and 3): having the right shims on hand.1979 GS 1000

I'm about to do my first valve job on the 450, how would I know which shims to order ahead of time?
Or do I have to wait til I get in there to find out, then order them and wait a few days til they arrive?

Note: I would order 1 extra, slightly smaller, so you can have some flexibility on moving shims around. Let's say you need (2) 2.55 and (2) 2.60 then order a 2.50 as an extra. Even though you might not need it this time around, other than a placeholder, you'll probably use it for the next time.

Update, and "don't give up" inspirational story (ha!)
Went to the dealer, they had a few 29.5 shims, but not what I needed. They gave me a number for an indy mechanic who used to work for them and now has his own shop. He had everything I needed, and they were used so I got them $3.00 each. Finish valve adjustment tonight. The moral of the story, don't forget local "shade tree" type guys who just might have what you're looking for thrown in a drawer somewhere.
