Throttle Body Sync Question

[tmfirestone]

I checked the throttle bodies on my 2007 R1200R yesterday using a Twinmax and found the left cylinder drawing more vacuum than the right. My question is what do I adjust to get them in sync?
Previous models had the big brass adjustment screw.

Thanks!

Most likely the valves.

There is no adjustment at idle. You can ignore idle - the ECU controls the air-passages that replaced the BBS via stepper motors. In all likelyhood - unless someone has dicked (tech-term) with your balance adjustment - getting the valves right will put it dead nutz on. Even though I wrote the DIY for balance for the BMW-MOA Hexhead forum, I've never had to actually adjust mine. Get the valves right, and the balance is right on (it's set at about 1,400-1,800 RPM..)
