    I've been reading a ton of info on here so I figured I'd give some back, here is some of the pics explaining the camshaft timing for the 1250, not much difference between the old 1200. Hope this helps some of you guys out!

    Yes, exactly like the Wethead, with a new tool set. Same torque values.

    Where did you get this?

    They are copies of the procedure, not complete and some info redacted. I hope I have not broken any rules being his is my second post. You can IM me if I need to remove it.

    No, not at all. I was just curious where you got them? The manual has not been released to the public yet.

    Yes curious also. Wondering if I want to grab the cam tools and continue on my adventures of checking 1250's along with 1200's. I am very curious if they are all over the place as the 1200's are?

    Well I'm sure the DVD service manual release will be soon, I do have the tool ordered, should get it today. Ill post a pic of the tool and the p/n to order, from your local dealer. The only difference is the removal and reinstallation of the shift solenoid, from the 1200 motor, as seen in the instructions. Lee, I'm also curious to see if timing is off, I know my 18' r1200 was at 6000mi.

    Ty for the scans - it looks like 2 new tools, "11 2 510/1", are needed for Shifty as compared to original LC tools - the tensioner and rest of the tools you posted seem carryover...

    Please post the p#s for tools you've got for future reference... :beer

    It may not be bad idea to cross-post the same info in the main thread on the topic: https://advrider.com/f/threads/using-any-gsw-special-tools.937091/

    The text implies (to me) that there is a left side and a right side alignment tool.

    Well still waiting on the tool. I think you can unbolt and flip the jig around for the opposite cylinder, but time will tell....shortly....hopefully Friday.

    I also agree looks like two tools in a set, but that could be a German to English translation error in wording. Again we'll see.

    Well they are the same number referenced so I hope it is one tool only.

    I've had my 1250 almost a year and the manual still hasn't been released... :baldy

    Hell, I had the video filmed a year ago, but didn't want to release it until I got a copy. I finally got confirmation on a few key factors values and torques, so just finished it 10 months after filming. I am still waiting on a copy of the manual though.

    Here is the tool, one p/n and you get the set. It retails for about $170.00

The camshaft flats 'if you can call it that' are parallel with the valve cover gasket surface. That means with a little ingenuity and a digital protractor you could effectively set the cams in the same position as the jig tool. Also you can set your camshaft centerlines relative to the zero'ed out point either advanced or retarded or a combo of both to change open/ closing points this would effectively change the overlap number as well. Awesome stuff, but hot rodding a GS is probably not to popular.

    Just like the Wetheads, it isn't necessary to have them exactly perfect for checking the valves:

    I did the same on the Shifthead, but visually:

    But for the cam timing, better precision is required.

    I could see carefully improvising, or 3D printing these BMW plastic blocks for Cam Timing adjustments.

    Thank you for this information. I'll probably order a set shortly.
