Shim kits for valves?

[Nessism]

Gotta be careful when ordering shims. GS shims are 29.5mm, but some suppliers provide 29mm instead.

Z1 seems to be out of 29.5mm shims. eBay sellers want almost $10 each these days.

I think if the shim club started up again, whoever drives it should charge $5/each, and charge a $5 core charge. That would make it worthwhile for all the effort.

Like I said…what sizes do you need? I have a well supplied set.

I should see Steve and Brian bwringer at BC rally. Will ask both if they mind putting it up on BikeCliffs. I’ve been sending it to people if the PM me with an email address.

Last time I checked with Steve, he was maintaining a list of users, so he could send out updates if/when they happened.
There have been no updates refinements for quite a while that I know of.

Z1 now has 29.5mm shims back in stock after a couple months of them being out, $5.25. Chapmoto sells them in specific sizes in packs of 5 for $43 (so about $8.60 each). Just before Z1 restocked I took a punt on ordering some from this Italian place for approximately the same price as Z1.

I discussed this with my machinist and the cheapest surface grinder we could find was $3,000
Plus, Ray way charging nothing for labor
It would cost more than $10.00 to set up a shim for grinding, much less the grinding time

I've seen that advice multiple times and keep wondering why this spreadsheet is not on the GSR archive.

Is the spreadsheet just an interactive version of the chart that's in the shop manuals? Looks like the 2-valve bikes all have the same chart, this is from my 450 manual but it is identical to the 650 and 1000 manuals I looked at.

Last week, I met with Steve. bwringer Brian has the file. He will get it up on BikeClffs Website when he gets a chance. Til then if someone wants it, here’s a link.

I had one of the blue metal box Suzuki sets when I had my 850. I think I got if from eBay for $150?? That woulda been like 15 years ago or more. There's one on there now just doing a quick search for $250/best offer, but it's about half empty.

I wanted a couple hundred bucks extra for it when I sold the bike in 2014, but the guy didn't want to pay for it (couldn't quite understand that). I sold it to somebody in Canada I think, for less than $100, and the transaction was kind of a pain.

Looks like there's slots in one of those for 120 shims. $600 at $5 each...

I think a 'shim club' is excellent.
I was glad to have met member 'Rusty Bronco' for the first time in Jul. 18' and he Really pulled me out of a jamb;he's in Marysville,MI. and I rode to his place.
He Really 'got me on the road' for the long trip West;even had a spare 29.5mm size shim I bought from him which I needed because I adjusted the 4 valves while I was there.

The 2V valvetrain on GS bikes is super stable. The adjustment holds a long time. Commonly, you will only need a handful of different sizes for the entire engine, for the life of the bike. With a shim kit, you won't use 75% of the sizes, so they just go to waste.

Z1 do a 20 piece kit for around $100

I bought one of these kits some decades ago. It seems like as it is used the old shims I put ack into the box tend to be very similar in thickness.
