Life does have it's interesting moments and surprises. For years I have frequented the AdvRider.com web community and have met several folks that have become friends. Recently I read a thread started by a gentleman about carburetor jetting of a 2006 KTM 640 Adventure for 7000 feet in elevation. The thread greatly interested me as I also have a 2006 KTM 640 Adventure that I ride at 7000 plus feet in elevation (Mexico City). I asked the originator of the thread a few questions and after a few replies we determined that we live within five blocks of each other in the Polanco district of Mexico City. Small world, eh! My new friend, Gustavo (dog'meat), was born in Italy and raised in Argentina moved to Mexico City four years ago due for a more central location to his business concerns in the USA and Argentina. After a couple of months of modifications to our bikes and the Christmas/New Years holidays, we finally synchronized our calenders and made a trip to the small mining town of Real de Catorce north of Mexico City in the state of San Luis Potosi. We were both eager to finally use our KTMs for what they were designed to do!
