oh wow, this is awesome. a lot of people who are brave enough to do such a task will be happy to see this. but it looks as if a lot of specialty tools are needed, so doing this job and having to buy the proper tools to do it might not be worth it in the end.

Thanks Clem!

Where can I get a supply of the hemispherical valve shims :dizzy:

It appears you buy them directly from BMW,

"Measuring adjuster, this is the same as the marking on the sphere - and the size BMW gives them in the part# description, very convenient. They sell for about $5.50 each and come in .05mm increments"

Thank you so much Clem, that's some great information.

DOHC Valve Adjustment

BMW's Semi-Hemisphere Shims.

These came out of my 2012 Roadster at about 25,000 miles. Save them, swap them to another valve position, or trade them with other owners.

These shims make the DOHC engine closer to being maintenance free.

Kawasaki and other Japanese bikes have used shim adjustment for years. The surface area of the shim is larger than the screw type adjuster, and extended valve adjustment periods are possible.

Thanks for the good info, Clem. I'll be doing this when mine's out of warranty.

Thank you! Very helpful !

checking valve clearances - twin cam models

Thanks for the info Clem , is it necessary to change the rocker cover seals each time you remove them , the BMW dealer i deal with tells me it is $150 aud for a rocker cover seal kit. Seems a bit expensive to me .
When checking same on my last r1150r , i changed the inner seal around the spark plug each time , as it would get very hot in there , and they were not expensive .
R12r has a different set up , has anyone looked into this ?

 

[Clem]

Seals

Nope. I don't think so. They will last for many years if slowly removed, carefully put back together, and torqued to spec.

 

[GordonK]

Thanks again Clem , i will re-use them & see how i go . I will advise sucess or otherwise in due course. Cheers

 

[shawn_speed]

One very important step that I missed in the post is engine temp. It has to be room temperature or the readings will be off.

 

[yonderbob]

I'm going to try this in about 2k miles. I though I'd be able to find a kit that included at least one each of all the possible shims I might need but I've had no luck.

Anyone know where they can be purchased in the US? BikeBandit has "universal" kits and ASCycles has the box they go in but the actual shims are not to be found. I don't want to take everything apart and find I need one and then have to put it all back together and start the hunt...

thanks

Bob

The SHIMS are $5.50 EACH! :dizzy: ah... BMW... If I want a kit with all the possible sizes I might need, (23 of them from 4.6 to 5.7 according to my trusty Haynes manual) $126.50. Then there are the E-clips which are probably $25.00 each... Is there a part number?

thanks

R U up to this Bob?:clown:Just pay the dealer to do it.

There are only 2 threaded fasteners on each valve cover.
You'll lose a tablespoon of oil.
Take the valve clearance measurements, do the math, and close it back up.
Don't forget to write down the thickness and location of each shim in the engine. You may be able to use some shims in another location.
Order the shims you need. Slide them in when they arrive.
Valve adjustments are so far apart, a thousand miles between measurement and replacement won't make much difference.

OR
You could buy a complete set, one of each size, and still need 2 of a particular thickness.

 

[yonderbob]

ok... scratch that first question... I found them on A&S Cycles web site. They are called "semi-spheres" and start with part # 11347721166 (the 4.6 size) and they are $6.57 each. Shipping and handling adds another $10, so $17 for this lilliputian deficient semi-ben-wa ball? I guess the strategy is to dismantle and check the valves on Sunday late, order the parts if needed and just leave the head covers off till the parts come in... oh, and measure twice because you don't want to do the whole process all over again... i'm sure there's a restocking fee!

Easier than the Honda was, Clem! Except for the bit where you have to pay $15 for a part the size of a bb! I doubt I'll even need a shim. If I need more than 2 it would be cheaper to pay the dealer to do it! :icon_scratch:

 

[Clem]

I hear ya' there Bob! BMW thinks very highly of their small baubles.:clown:
You can use the shims in another location, if you're lucky.
Not a difficult process, just a bit tedious.
I just like getting oil on my hands while tinkering,:001_tt1: so I don't mind.
Hey, post some photos for us. Like they say,
No pictures, it didn't happen.
