I´ve ordered a new 525MXC with 13L (about3.4Gln) fuel tank. I´m living in the central cordillera of the Andes in Peru and will use this bike for driving between 8000 and 15000 feet altitude. What kind of autonomy can I expect with the standard 3.4 galon tank at regular speed (not racing)?What size of carburator jet is best convenient for circulating at this altitude? In this region (Ayacucho) is only fuel octan 84 and sometimes 90 available. Thanks for your suggestions and comments.
