I´m sorry for you. But you´re shooting with cannons at sparrows now. I take it
- you´re not seriously bodily hurt
- you got time on your hand
- you got some financial backup
- you have friends in Russia who would be able to help you contacting folks by phone and to some liaison work.

Another good thing is you´re in Russia, which does have more in-country service than you would think.
Now, either you throw some money at your bike in Russia and have it repaired by a Beemer service. Get in contact with ABTODOM - Automotive - Москва | Facebook or BMW Автодом : АВТОДОМ - официальный дилер БМВ, МИНИ, АЛЬПИНА. | ABTODOM - the official dealer of BMW, MINI, ALPINA. in Moscow and they will most certainly be able to give you some advice whom to contact for repairs down there where you are or be at least able to tell you how to get the parts. I have found sufficient mentioning of AVTODOM (notice the different spelling on Facebook) to believe they have a Motorcyle branch too, even started a BMW motorcycle club up there and would speak English. Approaching them via FB may even get you some help from local folks. It´s not rocket science to fix the front end of a GS and there´s lots of mechanics in Russia. But even if it is: Remember they went to space first :-)

Or you sell the bike as is, cough up the money for the import duty and purchase a straightforward japanese bike locally. Running back to good ol´ Europe won´t be so much helpful timingwise or costwise, if you add all up.

Don´t give up, buddy. This is part of the trip!

Cheers
Chris
