Valve Shim Diameter for Wet Heads?

Can someone tell me what the diameter of the Wet Heads valve shims are?

I want to say 7.48 but I also think I have read 8.90?

Just prepping for the 12K check coming on soon.

TIA

I don't know you answer, but I am wondering why you want that, as all is required is the next shim in line from current (thats how the LT worked). If you are only at 12K (miles) & I just did my 20Klm which is a check valve clearance & I didn't require any replacement of shims & from what I have seen others say you could expect 40klm maybe before you would require shim replacement.

Re: Valve Shim Diameter for Wet Heads?

Realoem.com says the same shims are used on these models:
K50 (R 1200 GS)   (10/2011 — 06/2017)
K51 (R 1200 GS Adventure)   (09/2012 — 06/2017)
K52 (R 1200 RT)   (01/2013 — 04/2017)
K53 (R 1200 R)   (11/2013 — 04/2017)
K54 (R 1200 RS)   (06/2014 — 04/2017)
K42 (HP4)   (09/2011 — 07/2014)
K46 (S 1000 RR)   (09/2008 — 06/2017)
K47 (S 1000 R)   (02/2013 — 04/2017)
K49 (S 1000 XR)   (05/2014 — 06/2017)
K03 (G 310 R)   (04/2016 — 06/2017)


Not finding much info searching on the wethead models, but the S1000RR guys seem to like the
Wiseco VSK4 Premium 8.90mm OD Valve Shim kit (23 sizes, 3 per size)

Apparently the shim bucket diameter is 8.90mm, the shims reportedly measure a bit less.

You might also want to download this spreadsheet to find the appropriate replacement shim:

Thank you so much for the info.

In all the searching I did on multiple forums find the spread sheet which is way cool.

That is the kit I am going to buy.

Bighopper I will invest the 40 something dollars to have shims on hand. I know everyone says they hold and stay put but my luck does not run that way. My motor does not seem excessively noisy but in the world of thousandths who knows until you measure. If any of mine are tight I will free them a bit.
As you know valves wear tight on these types of motors. That is my fear.

And I have pounded this bike twice on a dyno. And it regularly sees over 100 MPH for periods of time. Every time it is ridden it does a Ton for a brief period of time so there is no telling what the valve settings will be.

I hope for the best and prepare for the worst.

Thanks again for the reply.

Re: Valve Shim Diameter for Wet Heads?

Lee - there had been discussions in the other forum about this, and 8.9 mm is the correct size. Apparently some of the guys had bought shim set (non-BMW) on eBay, and they are also available on Amazon for (if memory serves) about $40 a set!

EDIT: Lee, this is the thread: http://bmwsporttouring.com/ubbthread...418#Post981418

Probability is high that you won't need to make any adjustments! Mine was well within spec when I did my 12k last year.

Yes the order was placed with my Prime Membership as soon as read the reply. I wanted a new set of feeler gauges as mine are old as the hills. Also everyone says about space and while I watched the JVB DVD I did not take notice. So I splurged and bought a tapered set. Also my micrometer was way old and while i do baby it and store it as a sacred thing I bought a digital one for like 20 bucks. I just want to take no chances.

So the JVB Video, a set of feeler gauges, a micrometer and a box of 65 shims, I am in a bit over a hundred bucks in my preparing for my valve check. I can live with that. Well I did buy a coil puller a while back but would need that for plug change anyway.

So in a month or less I will do my 12K valve check and change my plugs over to iridium. Always a pleasure to be prepared and do ones own service work.

I wish someone with those 300 dollar plus cam timing tools lived close I would love to know but too rich for my blood right now to buy them myself. They have gone up in price since they were originally discussed.

Since I do not know anyone I guess I am stuck with my wooden dowel and a piece of electrical tape around it at TDC

You missed my edited post! Take a look, because I had quoted the link to the thread that was in the other forum.

Heck, my micrometer, that I am still using, was older than the hills! I was a "certified" toolmaker before I had gotten my first engineering degree, and I still have some of the instruments that I had used back then. This particular 0 - 1" mike was given to me by another toolmaker, back when I was poor and couldn't afford much. The darn thing was in a flood, or something like tha, and it was rusted solid. I took it, and used an ultra-sonic cleaner to free everything up, took it all apart to clean and lube before putting it all back again. The thing still measure true, because in the (relatively) recent years, it had been subjected to annual calibration by the QA department, until my retirement in '08! My feeler gauge set was from those days as well, and of course they were marked in inches, and so I am going to have to buy a new one in metric for the next time!

The wooden dowel method is the quickest was to find TDC! That is exactly what I did, and then reconfirm with the JVB method with a good straight-edge!

Re: Valve Shim Diameter for Wet Heads?

Great shim kit find. About 3 years ago I spent several hundred $'s on BMW OEM shims.
I have one thing to add. Over the years I have looked for a proper metric feeler gauge set. I finally found one in .02mm increments and it is not too expensive.
Metric Feeler Gauge Set
Also, I do have that set of cam timing tools. I have found the valve clearance is super stable but the cam timing can drift. And even found it off in 3 out of 4 new bikes at the 12,000 mile check. I know JVB poo poo's the need and suggests putting a straight edge on the cam ends. This is a rough idea but does not indicate small changes that the real tools will show. Just putting in the cam chain tensioner tool will change the timing enough to make go/no go changes to the timing. If you don't use it when checking cam timing, you have no real measurement.
BMW wet head shim spread is 1.72mm to 2.40mm. S bike is 2.00mm to 2.40mm. If that matters to you. Like the man said, they measure in diameter a tad under 8.9mm in diameter but that is just the fit situation. You may find half sizes when you do your work. The factory has access to them. They do an amazing job setting up the original clearance, computer I guess. I have the cam tools for the wethead and now need them for the S bike as I have one of the little beasts.

Not sure what size the shim is but most likely your valves will be in spec. Just did mine and they were right where the should be.
