Hi Paul & Angie,

Sorry for the incredibly late reply - a combination of excuses but mostly my crapness!

To answer your questions, we tend to get about 30km per litre (sorry we're runnnig mettric as once you leave the UK it all is) fully loaded which doesn't seem to change much weather cruising on tarmac or in the dirt on mountains so our light comes on at about 260-270km giving us a little over 400km to tank (we also carry a plastic 5 ltr jerry can for those places where we need it.
Our route is UK - Turkey, Caspian Sea - Stans - China - Pakistan - India (where we currently are) Nepal - SE Asia to Singapore and who knows where after that!

And yes, we have a blog, feel free to have a look and pepper with questions you might have. It's motoventurers.com
