Can someone tell a new 2012 R1200GSA owner how to sync the throttle bodies using manual gauges and no GS-911?

I use a homemade manometer (1/4" aquarium tubing with a few CC's of colored oil) taped to a broom handle and one line pinched with a set of forceps. Connect the tubing tot eh barbed fitting on the throttle bodies, start the bike and undo the forceps and watch the oil to see if one side is pulling harder than the other.
Be know the bike should be up to operating temp before TB balancing is to be done and also keep the forceps handy in case one side is really pulling hard clip the forceps on either line to keep the oil from being sucked into the motor. If if does get sucked in its not a huge ordeal it just be a bit smokey in the garage.
No GS911 tool needed. Adjustment is manual IF needed.

I used the tubing method too, something like this. Key is getting each side equal length to have a good balance.

Some videos out there on the process, I recall using this one and others. I balanced mine at 3500-4000 rpm as that is where I was getting buzziness.

Great Post.
On a 2017 R1200GS LC can this be done using the GS 911?
Found a video here, not sure if it accomplishes the same result...hoping to smooth out vibrations at 4200 rpms...

I don't think the liquid cooled bikes need syncing.
Just curious, what does being liquid cooled have to do with syncing throttle bodies. All my bikes are liquid cooled and once a year I check the throttle bodies and balance if needed.

Ride-by-wire throttle body sync?
So, ride-by-wire------how do you sync the throttle bodies? Is it done in the usual way or via a software manipulation? The dealer salesman didn't know and the service guys were gone for the day. Just curious because I do my '07 R12R with a CarbTune and I'm in the process of buying a '15 GS.

very interesting, I would recommend looking in the service manual to see what it recommends. I took a look at the service intervals and it doesn’t list throttle body balancing as part of general maintenance. If they are electronically adjusted by the ECU that’s pretty cool. Thanks for the info.Ride by wire

For oil cooled bikes I don't think it is a normal interval item, ultimately isn't needed unless you need to reduce vibration at certain rpms.

I have two triumph rockets, they are both fuel injected and yes you are correct, they do not have carburetors.. they do have throttle bodies, three to be exact and as part of normal service intervals they need to be checked and balanced if required. I use dealertool along with a OBD2 cable to perform this task. If this does not need to be done on the gs then that’s another thing that I don’t have to worry about. Win win…Fuel injected bikes don't have carburetors to sync

Every 12,000 miles. Easy to do after valves are adjusted.
This would be on the oil cooled bikes.
As expected, thanks. I would have been very surprised if it did not have to be checked. Service manuals take the guess work out. I own the manuals for all my bikes, next purchase… one for the 1250.
Cheers
