I am in San Juan which is about 80 k north of Mendoza Argentina I have a 2007 BMW GS 1200 and it is not running. At first I thought it was fuel with water in it. We drained the tank and took it off and flushed it out with alcohol so it was dry. We took off the fuel pump and check the mesh bag on the end of it. We filled two bikes with the same fuel pump and the other bike is running fine. We thought we had the problem fixed and took off and made it about 60 k north of San Juan and it did the same thing as before. We do not think it is fuel this time as the other bike was running fine. We think it is the fuel pump as it runs fine at times and you can go for 2 or 3 miles and then it kills again. It does not backfire or anything. It just kills. You let it stand and it seems to run for a bit. You might make it 30 feet or 1 mile before it kills again. We have tried leaving the gas tank open and it does not help. We took the tank off and flushed it out so I know that there is not water in it from before but we did have some in it before. We could see it going out of the hose we used. We find it hard to believe that it could be bad gas from two different towns and two different pumps. And the fact that two bikes were filled with it at the same time and one is having the problem. The last time we had the trouble we each used a different grade of gas. He used 95 and I used 97 and I had the problem. This time we both used 97 but he has not had problem at all. What I need to know is is there a BMW dealer in Mendoza as I have limited internet to search. The other bike has gone on now so I am alone with my wife. We are back in San Juan drinking so life is not totally bad. I have someone lined up to haul my bike to Mendoza but not sure if there is a BMW place there that can diagnose the problem and get me parts to go. It really sucks to not trust it. Today it ran fine for 60 k and then just started doing the same thing again. grrrrrrrrrrrrrr any help would sure be appreciated.
