I'm in South Chile on my 1995 f650 which has a maximum range of 250mls -350km - BUT
that is with good fuel and on good roads. I've run out a couple of times but carry a couple of ltrs and that got me out of trouble the first time, (I took a wrong turn
- thanks Garmin -
) the second time was in Bolivia on a pig of a road across mountains and through rivers where my fuel consumption went down to 150mls - 240km - due to all the low speeds and high altitudes. My f650 has a carburetter with a vacuum compensator, but this only works when you get some revs on, otherwise the engine is running rich all the time.
Lucky for me I had some petrol in my camping stove, and that got me to the next petrol station.
Also I expect my air filter needed cleaning which didn't help.
Now I carry about 4ltrs in a platic container, but checking my map of Argentina I don't think I will need it, but you never know.
I heard on the news here that Ecuador had some trouble with supplies due to roads being washed out during recent floods,
same goes for N.Peru, but I came through after the first few storms in Feb, and although the rivers were swollen they had not yet washed away the roads.
I spoke with Duncan-the-cook in Arica and from his experience I think you can rely on people to help you out if you do get stranded for any reason.
I'll let him tell his tale when he gets on line, (Hi Duncan, those private mechanics in Santiago are great - see seperate thread)
