Throttle sync? Don't know that you can. It's a fly by wire bike. No cables to adjust. No idle air bypass screws. That said...

There are two tubes that go to the right side head near the throttle body and one that goes to the left side head. I assume that one of the two on the right is to purge the US mounted evap canister. Don't know what the other left and right tubes are for (or where they go). They could be what you are looking for.

Good point, hadn't thought about that. One less thing to adjust unless you have the BMW computer I guess.

Thanks

Throttles are synced automatically by the computer on the GSW.

I believe they cycle through the full range of motion during the self-check when you switch on the key to calibrate/sync the stepper motors... However, my dealership mentioned they require recalibration every (I believe) 24,000 miles which is done by connecting to the BMW service computer... I can ask next Saturday when it’s in to service the exhaust flap mechanism...

Those two tubes are for making swirl in the intake air,
one of the things that improve the combustion and make them get rid of the secondary spark-plug.

My exhaust flap was found seized up on my 18k service. Had it replaced today, complete new exhaust pipes fitted as flap valve itself is not serviceable.

Good to know, but not sure why you quoted the post that you did...two separate issues.

Did they replace the end can, or the whole system, with headers?

The headers upto, but not including, the silencer. Not sure why it has changed from previous models where the exhaust flap was removable as a separate unit??

GSWC frame redesign for 2014?

Anyone aware of a frame redesign for the 2014 model? Recently spoke to a buddy with a 2013 WC GS that had his upper fork cross brace/handle bars end up in his hands (not attached to the bike) after the steering head part of the frame failed and the upper fork brace came out. Showed me a pic of the steering head tube after failure and how thin it is where the bearing goes in. He's getting a new frame from BMW and I understand it's redesigned, although maybe for the dampener or something else - haven't confirmed the redesign is to address the weakness he experienced.

Granted, he rides his bikes hard...

Was he jumping?

The 2014 frame is a different part number, but I haven't read anything about whether there are any other changes aside from the lower front where the crash bars are attached (the new damper attaches to the A-arm).

Not sure if he has on the GSWC, but here he is at Overland Expo AZ in 2012 on a Rawhide provided bike:


and on his previous GSA:


I heard today from another GSWC owner/buddy I work with, after I told him about it and he asked a contact at the dealer about this issue, that another guy may have suffered the same or similar steering head issue, and that the redesign sounds like it addressed this weakness. I'll get more detailed info and pics and post up later...
